Abstract Sustainable manufacture caused shift in automotive manufacturing practices. Polymer‐based composites make up almost 15% mass of the entire vehicle, most importantly fuel system vehicle. Poor electrical conductivity polymer leads to electrostatic deposition, which can lead issues. Carbon based synthetic fillers like carbon fiber and nanotubes are attractive options develop electrically conductive composites, owing their excellent mechanical properties. However, production process...

Punch shear in unidirectional composites is induced by transverse loading that progressively perforates the laminate within a narrow annulus. At lower micromechanical length scales, punch creates unique damage mechanisms dominated fiber failure, fiber–matrix interphase debonding and large inelastic deformation cracking of matrix. A new experimental method has been developed to test S glass/DER353 epoxy composite ribbons at sub-millimeter scale. The data consist statistical measurement...

Wood plastic composite (WPC) materials are being developed for load-bearing structural applications; therefore, the strain rate-dependent mechanical properties of WPC need to be characterized.
