Abstract

Fracture behavior of rubber modified injection molded poly(butylene terephthalate) (PBT), with and without short glass fiber reinforcement was investigated using the fracture mechanics approach. Fracture tests were carried out on notched compact tension specimen. The effects of controlling parameters such as type of impact modifier and deformation rate on fracture behavior of PBT and rubber toughened PBT were examined. Results indicated that fracture toughness of PBT improved with the incorporation of glass fibers.
