Abstract

The tensile behavior at 20 DegC of polystyrene (I) [9003-53-6]-glass bead composites was studied at glass concns. from 0 to 25 vol.%. To gain insight into the role of interfacial adhesion, the bonding between glass and I was varied by using different silane coupling agents [Z-6032 [34937-00-3] and CH2:CHSi(OEt)3 [78-08-0]]. In contrast to the elastic behavior, the crazing behavior (i.e., the crit. applied tensile strength for craze formation at beads) of the composites was considerably affected by the degree of interfacial adhesion. This is explained by different mechanisms for craze formation at adhering and nonadhering glass beads, resp. Both elastic and crazing behavior of the composites were influenced by the glass bead concn
