On the Mixed Mode I/II/III Translaminar Fracture Toughness of E-glass/Epoxy Laminated Composites

In this paper, the mixed mode I/II/III translaminar fracture of glass fiber reinforced composites system wasinvestigated. Compact shear tension (CTS) was utilized to measure translaminar critical strain energy release rate(TCSERR). The samples were made of epoxy resin and fabric E-glass fibers. The CTS specimens were loaded by anovel test setup. In addition to pure modes I, II and III TCSERR of E-glass/epoxy system, a full series of mixed modetests were conducted. Finite element analysis was also carried out to calculate the calibration factors related to theTCSERR formulations. It was resulted that by increasing the mode II or III contribution, the TCERR of E-glass/epoxylaminated composites is decreased.
