Abstract
The effects of staged curing technique on the interlaminar fracture toughness, in-plane shear strength and void content were investigated experimentally. The specimens were fabricated with Hercules AS4-3501/6 unidirectional prepreg tape. Two types of staged curing cycles were considered along with the manufacturer's recommended cure cycle. The void content of each specimen was observed after testing to qualify its effect on mechanical test results. It was shown that no degradation in interlaminar fracture toughness or interlaminar shear strength could be found for the cure cycles used in the study. A reduction in void content was obtained by utilizing a cooldown stage between compaction and curing. The results show that the staged curing technique can be utilized to make thick composite laminates which are uniformly compacted with reduced void contents.
