Abstract
In this paper the structure of stamped glass fiber/polypropylene composites with different fiber/matrix interfaces is characterized and related to their short term mechanical behaviour. Optical microscopy and calorimetry are used to determine matrix and interface structure. Static tensile and flexural tests were performed but were less sensi tive to interface structure than impact. Extensive crystal nucleation observed on fibres, believed to be promoted by shear nucleation during stamping, did not correspond to a strong fibre/matrix interface.
