Abstract:The present work aims to study the mechanical performance of glass fiber reinforced polybutylene terephthalate (GF/PBT) composite materials used for high-pressure casing under different thermal aging temperatures. Both tensile and three-point bending tests are conducted on the thermally aged GF/PBT samples. Meanwhile, the stress analysis is performed using the finite element method, and the tensile fracture morphology and mode are observed using a scanning electron microscope. The findings reveal a decline in … Show more
