Binder applications have found their place in liquid composite molding processes, as they simplify preprocessing steps such as preforming and subsequent handling. Moreover, binders can modify mechanical behavior of finished fiber reinforced plastic parts. Besides the obvious potentials, topics such as the impregnation behavior become more complicat...

Thermoplastic tapes have found a prominent place in automated tape placement (ATP), due to their reduced processing time. ATP also offers significant reduction in labour; however, the most attractive aspect is the use of its welding properties. Welding or diffusion bonding is necessary for two thermoplastic materials to bond to each other through t...

The importance of preforming techniques is constantly increasing due to the fast development of liquid composite moulding processes. Besides traditional preforming methods such as tufting and stitching, tackifier based methods have developed rapidly. This paper presents a new methodology utilising 3D-printer technology for fabrics, through preform...

The curing behavior of a fiber reinforced polymer (FRP) composite part is interesting for both the industrial and scientific community for it is related to process optimization, quality upgrade and material characterization. The study at hand focuses on the potential of temperature measurements as a means to monitor curing; kinetic analysis which c...

In this paper a novel method to apply binder onto fabrics is introduced. Therefore, 3D-Printing technology namely Fused Deposition Modeling (FDM) is used to apply a thin melt strand onto a textile. The FDM technology uses an extruder which conveys a thermoplastic filament into a hollow cylinder. At the end of this cylinder a heated nozzle is situat...

For composites manufacturing processes such as automated fibre placement, filament winding or pultrusion, roving behaviour is crucial. Understanding and controlling these processes is only possible if material changes induced by guidance to the processing area are fully understood. Fibre placement system manufacturers such as Coriolis Composites us...

The Christian Doppler Laboratory for High Efficient Composite Processing aims to elaborate on a basic understanding of different processing routes making it possible to manufacture high load bearing structural components as found in aerospace applications. Apart from background information and motivation, a more detailed description of the research...

To improve the reliability of printed circuit boards (PCBs), occurring failure modes have to be studied and analysed. In order to reduce the expenses of experimental testing, finite element analysis (FEA) is used to describe the failure behaviour. Therefore, the availability of the proper material data is crucial. As the materials used in printed c...

A number of elastomer components are exposed to complex loads which results in a biaxial stress/strain state in the specimen. Hence, the characterization and modelling of the biaxial deformation behaviour is of prime practical importance. However, due to the large degree of deformation, the characterization and modelling of the biaxial deformation...
