Effects of Processing Temperature and Layup on Springback

Tests were performed to assess the effects of processing conditions and laminate layup on the change in shape (springback). Twelve inch long and one inch wide coupons made of Fiberite T300/976 graphite/epoxy were tested. Coupons of different layups were cured using different types of molds and different types of vacuum bagging arrangements. The curing was performed with different temperature cycles. Springback was measured from the change in...
