Abstract:In this report, details on the toughening of epoxy matrix composites by the polysulfone was described
to be adapted to great-distortion conditions. The mechanics capabilities thermal performance and micro-morphology
were investigated by kinds of analysis method. The results showed the composite material offered good compabilities,
such as flexural strength of 1 206. 3 MPa, interlayer shear strength of 111. 5 MPa,interlaminar fracture toughness of 1
108. 9 J/ m2, as well as, the materal worked well at 130℃. The curling test is succusful with the curvature radius less
than 20 cm, proving the great performance.
