Method of Fabricating Composite Laminate Structures Allowing Ply Slippage During Forming

摘要

A composite structure having a contoured cross section is fabricated by assembling a flat ply stack and forming the stack. The full plies in the stack are tacked through their entire thickness and the partial plies are tacked to individual ones of the full plies in a manner that enables the plies to slip in relation to each other, preventing wrinkling and distortion of the plies during forming.
