Abstract
Two-dimensional heat transfer analyses for non-isothermal molding of amorphous thermoplastic polymers and composites are presented. Solutions of the heat transfer analyses were obtained using the finite element technique, which includes convec tive heat transfer from the boundaries of the specimens. A non-isothermal autohesion model was developed by coupling the heat transfer analyses with an isothermal autohesion model for Udel P1700 polysulfone. The resulting computer code allows prediction of the time required for crack healing in amorphous polymers and autohesive bonding of the ply interfaces of fiber-reinforced composites under non-isothermal processing conditions. Results of the model are compared with data obtained during crack healing of Udel P1700 compact tension specimens and compression molding of 64-ply graphite/polysulfone com posites. Agreement between the model and data was good.
