摘要：

Fatigue crack propagation has been studied in injection-molded plates of unfilled PBT and composites filled with short glass fibers of varying length and in different volume fractions. Materials filled with glass spheres and short glass fibers have also been investigated. The influence of crack propagation direction and of the microstructural composition on crack speed is discussed. It is found that a model which accounts for the fiber orientation distribution, the skin-core morphology and the change in failure mechanisms due to variations in the fiber length and aspect ratio can explain the differences observed in crack propagation behavior.
