The effect of fiber inclusions in toughened plastics – Part II: determination of micromechanical parameters
Source abstract
Abstract
Short glass fiber-reinforced nylon 6,6 with and without rubbery inclusions were injection molded into standard specimens. The mechanical properties and the residual fiber length distribution were measured. The macro-to-micro model proposed by Bowyer and Bader [J. Mater. Sci., 7 (1972) 1315] was used to determine the interfacial shear strength (IFSS). The IFSS in the toughened nylon 6,6-based composites was found to be superior to that in the untoughened nylon 6,6-based composites. This indicates that the presence of rubbery phase in the composite system contributed to the interfacial bonding between nylon 6,6 and glass fibers (GF). Back-scattered electron imaging taken on a plane perpendicular to the mold filling direction for fiber-reinforced toughened nylon 6,6 showed that the rubbery phase adhered to the GF surface. This morphological feature was regarded as a main factor responsible for the improvement of IFSS in the reinforced toughened nylon 6,6 composites. (C) 2004 Published by Elsevier Ltd.
