Mode II fracture toughness of glass–epoxy laminated composites under various heating conditions and strain rates

The high performance of glass fiber reinforced polymer (GFRP) leads this composite to become one the favourite research topics in engineering. GFRP is widely used building structure and other engineering application. In design structures, damage-tolerant consideration essential, especially under environmental factor dynamic effect. Hence, damage stability loadings should be investigated. study, mode II fracture toughness glass/epoxy laminated evaluated various strain rates heating temperatures. specimens were fabricated by hand layout method with heat-treated temperature 40 °C, 60 °C 80 °C. experimental data obtained from end-notched flexure (ENF) test rate 1 mm/min 5 min/min. results showed that laminate increase rate. However, relatively insensitive temperature..
