Effects of Processing Temperature and Layup on Springback

This is the authors' abstract. We don't add key points for this paper.

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 shape of initially flat coupons. The results indicated the effects of the applied temperature, applied pressure, material of the mold, arrangement of the teflon surrounding the coupon, and laminate layup on springback.
