    ABSTRACT: Composite shafts can be damaged because of unsuitable production, mistaken assemblage, and excessive strain. Repairing of damaged composite shafts with patch or an alternative approach is an economical solution. This study aims to enhance the tensile, compressive, and four-point bending loads of notched E-glass/vinylester composite pultruded shafts by repairing with different patch materials. For this purpose, the notched composite shafts having 1 mm, 1.5 mm, and 2 mm notch depths were repaired with E-glass woven fabric, rib knitting fabric, and milano knitting fabric with 30 mm, 50 mm, and 70 mm widths by winding method. The results of the repaired composite shafts were compared with unrepaired composite shaft to better understand the influence of type and width of patch and notch depth on the critical damage load. The results showed that the repairing with E-glass woven and knitting patches increased the critical damage load of notched composite shafts by about 67%.

    ABSTRACT: Low-velocity impact analysis of 3D woven hollow core sandwich composite was conducted experimentally and numerically. Damage modes, perforation loads, load-time and energy-time curves, contact time, force-displacement and deflection-energy relationships were studied for three energy levels on specimens with different thicknesses utilizing both FE simulations and low-velocity impact tests. According to the results, contact stiffness and perforation load decreased with the panel thickness, whereas panels of higher thicknesses exhibited higher energy absorption capacity. The FE model consisting of glass fabric and surrounding resin reasonably predicted the impact behavior and damage modes. Subsequently, it could be inferred that FE simulation is capable to be used instead of time-consuming experiments to study impact properties of such materials.

    ABSTRACT: The compressive behaviour of epoxy based syntactic foams filled by ceramic microballoons is experimentally investigated in this study. Nine different types of syntactic foams are fabricated with three different microballoon sizes and three different microballoon fractions. All of the syntactic foam specimens are tested at various strain rates from quasi-static to high strain rates. Analysis of the results is carried out on the effect of the volume fraction, microballoon size and strain rate on the compressive behaviour of syntactic foams. Also, scanning electron microscopy is used to understand the fracture mechanisms of tested specimens. The results show that as the microballoon volume fraction increases the compressive strength, compressive modulus, failure strain and plateau stress decreases for all types of syntactic foams at all strain rates. Although, this decrease is slight for 20% and 40% volume fraction, it is considerable for 60% microballoon volume fraction syntactic foam. The results indicate that reducing the microballoon size or increasing the strain rate of testing would enhance the compressive strength.

    ABSTRACT: Layered packages consisting of 50 µm thick Al and Ti foils were used for producing metal-intermetallic laminate composites by a reactive sintering. The sintering was conducted at 630℃ and at a pressure of 25 MPa under the action of pulsed or direct current, which allowed the accelerated production of Ti/TiAl3 metal-intermetallic laminate composites without melting Al layers. Optimal characteristics of the electrical current flow through the 1–3 mm thick packages enabling the sintering time reduction by the factor of 1.5–2 as compared to the static hot pressing have been found. Possible mechanisms of the electrical current influence on solid-phase reactions in the laminate systems include Joule heating, the grain boundary electromigration, and the electroplastic effect.

    ABSTRACT: Conducting polymer/ferrite nanocomposites with an organized structure provide a new functional hybrid between organic and inorganic materials. The most popular among the conductive polymers is the polyaniline due to its wide application in different Eelds. In the present work nickel ferrite nanoparticles were prepared by sol–gel citrate-nitrate method. Polyaniline/nickel ferrite nanocomposites were synthesized by a simple general and inexpensive in-situ polymerization in the presence of nickel ferrite nanoparticles. The effects of nickel ferrite nanoparticles on the DC-electrical and magnetic properties of polyaniline were investigated. The structural, morphological and thermal stability of nanocomposites were characterized by X-ray diffraction, FTIR, scanning electron micrograph and TGA. The DC conductivity of polyaniline/nickel ferrite nanocomposites have been measured as a function of temperature in the range of 80 K to 300 K. The magnetic properties of the nanocomposites were measured using vibrating sample magnetometer in the temperature range 300–10 K up to 30 kOe magnetic field.

    ABSTRACT: Three-dimensional (3D) fabrics of commingled yarns offer the possibility of a low-cost and fast manufacturing of complex-shaped composite parts. Textile-reinforcement behavior during the forming process is very important since the appearance of defects (for example wrinkles, yarn misalignment or breakage) can significantly affect the mechanical properties of the final part. Experimental characterization of the mechanical behavior of textile-reinforcements is expensive, time consuming, and a large scattering of results is often observed. To overcome this, meso-scale modeling is an interesting method to study and understand the textile behavior at the unit cell level. To perform realistic simulations, an accurate modeling and, therefore, knowledge of the yarn mechanical behavior are needed. In this paper, a simple protocol is proposed and validated in order to investigate the tensile behavior of commingled polypropylene/glass yarns. Influence of specimen length and strain rate are highlighted. A comparison of tensile behavior of yarns before and after weaving is carried out in order to evaluate the weaving damage effect. Finally, a model describing the commingled yarn behavior is proposed. The parameters of the model are defined. Their dependency to strain rate, specimen length, and weaving damage are highlighted.

    ABSTRACT: A material model for unidirectional fibre-reinforced composites coupling damage to the friction acting on newly created microcracks is developed. While existing material models accounting for progressive damage assume that microcracks remain traction free under compressive load, the present model accounts for contact and friction at microcrack closure. The model is validated against experimental data and it is shown that friction can account for part of the non-linear response and the hysteresis loops typically observed in the shear response of composites. Further validation against simple crushing tests is performed and shows that the physics behind crushing is well captured.

    ABSTRACT: Unidirectional tape-placement technologies appeared as a promising alternative due to their potential in large-scale component production. While the optimization strategies used to define the tape lay-out can be of different nature, the utilization of tape-to-tape joints is inevitable. Whereas several studies have focussed their efforts on the process and design stages, no study has yet addressed the influence of the manufacturing process on the mechanics of unidirectional tape joints. In this study, the strength of single-lap-joint assemblies of carbon fibre-reinforced thermoplastic tapes under tensile loading was analysed. The dependence of the strength on the overlap geometry and the manufacturing pressure was of main focus. Single-lap-joint assemblies with rectangular and rounded overlaps of the same overlap area were prepared employing a pre-heating stage at 250℃ and forming pressures from 3 to 100 bar. Failure of the assemblies was not observed on the overlap itself but instead on the zone near the overlap end on the adherend. Traditional determination of strength of single-lap-joint assemblies is not applicable in this case. Consequently, a typical Hashin failure criterion was used to model the failure of the assemblies. The study showed that although cohesive failure is not likely within the analysed pressure range, overlap geometry and forming-pressure affect the strength of single-lap-joint assemblies under tensile loading.

    ABSTRACT: An investigation of the fabrication-induced distortions in fibre metal laminates is presented using finite-element modelling and experiments. Cooling down is considered as the main source of distortion. Four fibre metal laminate panels are manufactured and their curvature is measured using digital image correlation and linear variable differential transformer. The curvatures are the response of the non-symmetric lay-up to different parameters like stacking order and number of composite or metal layers. Acceptable agreement between model and experiment in predicting the geometry shows that the laminate shape can be predicted with reliability. A large displacement model should be used for large shape deviations in laminates with high level of non-symmetry. Fibre metal laminates may have single or multi-stable configurations after removal from the layup tool. This phenomenon is analysed and parameters and modelling considerations are investigated to obtain a method to predict the final configuration. Further modelling and experimentation are needed to improve the quality of the predictions with increasing complexity of the component.

    ABSTRACT: The protection of steel against corrosion by nano-glass flake containing coatings has been evaluated in this article. Nano-glass flake was incorporated into epoxy vinyl ester resin by mechanical agitation, homogenizer and sonication process. The dispersion morphology and agglomeration degree of nanoadditives were analyzed by optical microscopy, scanning electron microscopy and energy-dispersive X-ray spectroscopy. The effect of micro and nano-glass flake on anticorrosion performance of epoxy vinyl ester coatings were also compared in a salt spray chamber. The influence of nano-glass flake on the thermal behavior of resins was studied using differential scanning calorimetry and thermogravimetric analysis. The results showed that corrosion resistance of coatings improves as the amounts of nano-glass flake increases to 1.5 phr. Nano-glass-flake-filled specimens display a better corrosion protection than the micro-glass-flake-filled ones.

    ABSTRACT: In this paper, refined one-dimensional (1D) beam theories are implemented for the free vibration analysis of laminated beams with compact and thin-walled cross-sections. The proposed models are based on the Carrera Unified Formulation (CUF), which was formerly introduced for the analysis of plate and shells and recently expanded to beam structures by the first author and his co-workers. CUF is a hierarchical formulation leading to very accurate and computationally efficient finite element (FE) models. According to the latest developments in the framework of CUF, refined beam models are implemented using either Taylor-like or Lagrange-like polynomials in order to expand the unknown kinematic variables on the cross-section of the beam. Equivalent single layer models result from the former approach. On the other hand, if Lagrange polynomials are used, layer-wise models are produced. In this work, a classical 1D FE formulation along the beam length is used to develop numerical applications. A number of laminated beam structures are analysed and particular attention is given to laminated box beams with open and closed cross-section. The frequencies and the mode shapes obtained with the present refined beam elements are compared with solid/shell FE solutions from the commercial code MSC/Nastran and, when possible, with those found in the literature. The Modal Assurance Criterion (MAC) is used for model-to-model comparisons so as to demonstrate the enhanced capabilities of the proposed formulation in investigating the free vibration characteristics of both compact and thin-walled box laminated beams.
