    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: A carefully designed formulation of dry cement powder for concrete canvas (CC), which is expected to have both high mechanical strengths and short setting times, is obtained by partially replacing calcium sulfoaluminate(CSA) cement with anhydrite at four levels (0%, 10%, 20% and 30 % by mass of CSA cement). The influence of anhydrite fineness on the mechanical properties of CC and its mechanical anisotropy are both investigated. X-ray diffraction analysis and isothermal calorimetry are used to investigate the underlying mechanism. Results reveal that increasing anhydrite content or fineness improve the mechanical strengths of CC and shorten its setting times. However, a slight decrease of mechanical strength occurrs at the later age when the replacement level reaches 30 wt. %. A large amount of unhydrous particles is found in hardened specimens. The CC shows higher mechanical strengths in the warp direction than in the weft direction, and it exhibits the lowest compressive strength in the through-the-thickness direction.

    ABSTRACT: The influence of the carbon nanotubes (CNTs) content on the fiber/matrix interfacial shear strength (IFSS) in glass/fiber epoxy composites was measured by means of push-in and push-out tests. Both experimental methodologies provided equivalent values of the IFSS for each material. It was found that the dispersion of CNTs increased in IFSS by 19% in average with respect to the composite without CNTs. This improvement was reached with 0.3 wt.% of CNTs and increasing the CNT content up to 0.8 wt.% did not improve the interface strength.

    ABSTRACT: This paper presents the results of a combined experimental and theoretical study of the strength, fracture toughness, and resistance-curve behavior of natural fiber-reinforced earth-based composite materials. The composites, which consist of mixtures of laterite, clay, and straw, are stabilized with controlled levels of Ordinary Portland cement. The compositional dependence of compressive, flexural/bend strength, and fracture toughness are explored for different proportions of the constituent materials using composites and crack-tip shielding models. The underlying crack-microstructure interactions associated with resistance-curve behavior were also studied using in situ/ex situ optical microscopy. This revealed evidence of crack bridging by the straw fibers. The measured resistance-curve behavior is also shown to be consistent with predictions from small- and large-scale bridging models. The implications of the results are then discussed for potential applications in the design of robust earth-based building materials for sustainable eco-friendly homes.

    ABSTRACT: The electrochemical and mechanical performance of composite anodes for Li+ batteries is greatly affected by the matrix porosity. The role of porosity in the retention of the electrochemical capacity and mechanical durability was investigated for composite anodes with polyvinylidene fluoride/acetylene black matrix and graphite or Sn microscale particles. Graphite anodes with porosities between 40% and 50% demonstrated reliable mechanical performance after electrochemical cycling and consistent electrochemical capacity above 45% porosity cycled at C/5 rate. However, graphite anodes with porosities larger than 50% had negligible mechanical strength. The results of the mechanical and electrochemical studies identified an optimum porosity of ∼45% at which the graphite anodes had the highest initial elastic modulus and good strength and extensibility, which also agreed with the properties of the polyvinylidene fluoride/acetylene black matrix for the same porosity. The mechanical performance of Sn anodes, however, was quite inferior to that of graphite, which was largely due to the large volumetric expansion of the Sn particles in the first lithiation cycle.

    ABSTRACT: It is extremely challenging to imitate neural networks with their high-speed parallel signal processing, low power consumption, and intelligent learning capability. In this work, we report a spike neuromorphic module composed of “synapstors” made from carbon nanotube/C60/polyimide composite and “CMOS Somas” made from complementary metal-oxide semiconductor electronic circuits. The “synapstor” emulates a biological synapse with spike signal processing, plasticity, and memory; the “CMOS Soma” emulates a Soma in a biological neuron with analog parallel signal processing and spike generation. Spikes, short potential pulses, and input to the synapstors trigger postsynaptic currents and generate output spikes from the CMOS Somas in a parallel manner with low power consumption. The module can be modified dynamically on the basis of the synapstor plasticity. Spike neuromorphic modules could potentially be scaled up to emulate biologic neural networks and their functions.

    ABSTRACT: Structural electrochemical composites, which are capable of carrying mechanical loads while simultaneously storing or releasing electrical energy, combine the components and behaviors of conventional polymer composite structures and electrochemical devices such as batteries and supercapacitors into a single multifunctional material. In order to analyze these systems more rigorously, this paper derives relationships and metrics for the mass savings of a multifunctional design relative to a design consisting of conventional structures and electrochemical devices. These metrics are then evaluated using structural supercapacitors composed of carbon fiber electrodes and conductive solid polymer electrolytes, as well as multifunctional supercapacitors from literature. The analysis reveals that state-of-the-art multifunctional supercapacitors are still far from reaching the levels of performance needed to supplant conventional structures and save system mass. The metrics provide further insight regarding multifunctional value of the material components as well as influence of various functionalities on system performance.

    ABSTRACT: A theoretical model is developed to study the fiber debonding and pull-out in hybrid-fiber-reinforced brittle-matrix composites. By adopting the shear-lag model which includes the matrix shear deformation in the bonding region and friction in the debonding region, the relationship between the pull-out length and the debonding length of fiber is obtained by treating the interface debonding as a particular crack propagation problem along the interface. The interface debonding criterion for the hybrid-fiber-reinforced composites is obtained by applying the energy release rate relation in an interface debonding process. The analysis is applied to hybrid carbon/glass fiber-reinforced epoxy composites, and the theoretical results have a reasonable agreement with the experimental data. The hybrid effect is studied and the effect of material parameters is discussed.

    ABSTRACT: A series of TWRP-AO 2246 composites consisting of textile waste rubber powder (TWRP), 2, 2-methylene-bis-(4-methyl-6-tert-butyl-phenol) (AO 2246) was fabricated. The damping property of composites was tested by dynamic mechanical thermal analysis (DMA); the morphology was characterized by scanning electron microscopy (SEM); the composites’ structure was characterized by Fourier transform infrared spectroscopy (FTIR); and differential scanning calorimetry (DSC) was investigated. DMA results showed that TWRP-AO 2246 composites appeared in only one damping peak when AO 2246 content was less than 30%, and the tan δ peak value as well as its corresponding temperature increased gradually with increasing AO 2246 content. However, a novel damping peak appeared far away the glass-transition temperature peak of composite with 40% AO 2246 concentration, and a great damping platform was constructed between double peaks with a wide temperature range spanning more than 100℃, which is attributed to the dissociation of intermolecular hydrogen bonds in AO 2246 enriched phase and thus realized phase separation. Meanwhile, the presence of intermolecular hydrogen bonds in the composite was confirmed by FTIR. Thus, a new type of high performance damping composite with TWRP as a matrix was developed.
