The Effects of Processing on Interply Bond Strength of Thermoplastic Composites
Source abstract
Abstract
The double cantilevered beam (DCB) Mode I fracture toughness test was selected to characterize the interply (autohesive) bonding of the prepreg plies during ther moplastic composite consolidation. AS4 graphite fiber/P1700 polysulfone amorphous thermoplastic prepreg was selected for study. The fractured AS4/P1700 DCB specimens were healed in a special fixture under different combinations of temperature, pressure, and time. The healed DCB specimens were refractured and the critical strain energy release rates ( G IC ) were measured. Pressure was found to be a key factor governing the healing process. Temperature and time dependencies of the interply bond development were also observed.
