| The manufacture of thermoplastic composites nor- mally involves compression molding that generates fiber dislocations known as kink-bands, which create stress concentrations able to cause the premature compression failure of a composite; nevertheless, the kink-band influence over the interfacial performance or failure of a composite tested under tension is not fully understood. This work uses Raman spectroscopy as a tool to map the axial stress distribution around a kink-band in an aramid/low density polyethylene single fiber composite. The stress distribution along the fiber was fitted to a generalized shear-lag model to calculate the interfacial shear stress; its maximum was found around the kink-band where the fiber interface was still bonded to the matrix, defining a localized stress concentration. | |
