Characterization of the tool/fabric and fabric/fabric friction for woven-fabric composites during the thermostam** process
The dynamic coefficients of friction for Twintex® commingled glass-polypropylene balanced plain-weave and unbalanced twill-weave fabrics at the tool/fabric and fabric/fabric interfaces during the composite the...

Design of an apparatus for measuring tool/fabric and fabric/fabric friction of woven-fabric composites during the thermostam** process
The thermostam** of prepreg woven fabrics shows promise as a low-cost high-volume manufacturing process for composite parts. One concern associated with the process is the unwanted formation of defects in th...

Discrete mesoscopic modeling for the simulation of woven-fabric reinforcement forming
A discrete modeling approach is proposed to simulate woven-fabric reinforcement forming via explicit finite element analysis. The tensile behaviour of the yarns is modeled by truss, beam or seatbelt elements, ...

Characterization of the fabric/tool and fabric/fabric friction during the thermostam** process
The thermostam** of quality composite parts using thermoplastic woven fabrics may require the use of in-plane forces to prevent fabric wrinkling for compound-curvature surfaces. These in-plane forces are dev...

Simulation of the thermostam** of woven composites: determination of the tensile and in-plane shearing behaviors
The numerical simulation of the thermostam** process for fabric-reinforced thermoplastic composites requires an accurate characterization of the fabric material properties. To capture the interaction of the ...

Simulation of the thermostam** of woven composites: mesoscopic modelling using explicit fea codes
A hybrid finite element discrete mesoscopic approach is proposed to model the forming of woven-fabric reinforced composites. The yarns are modelled by 1-D elements, and the shearing behaviour of the fabric is ...
