Methodfor reducing ply wrinkling of composite laminates during forming

摘要

Ply wrinkling during hot drape forming of a composite laminate is reduced at corner radii. A tensioning material placed over an uncured composite laminate charge maintains a compressive force on the laminate charge as the charge is formed over a tool.
