Title
(EN) FABRICATION PROCESS FOR THERMOPLASTIC COMPOSITE PARTS AND PRODUCTS OBTAINED THEREBY
(FR) nouveau processus de fabrication de pieces composites thermoplastiques
Abstract
(EN)
A fabrication method of forming a thermoplastic composite laminate material (20) with tailored and varying thickness (tl, t2) in a continuous process. This process utilizes automated equipment or hand lay-up to collate parts or components into a multi-layer stack (74, 76). Each stack contains all plies, including ply build-up areas, tacked in the proper location to maintain orientation and location. The consolidation tooling contains all necessary part features and is coordinated to the customized multiple ply stacks to form a single integrated thermoplastic composite laminate potentially having areas of 10 differing thickness from these multiple ply stacks.
(FR)
L'invention a pour objet un procédé de fabrication en continu d'un matériau stratifié composite thermoplastique aux épaisseurs sur mesure variables. Le procédé fait usage d'outillage automatisé ou de laminage à la main pour assembler les parties ou les composants en une pile multicouches. Chaque pile contient toutes les couches, y compris les zones de surépaisseur, disposées aux emplacements adéquats pour conserver orientation et disposition. L'outil de renforcement comprend toutes les caractéristiques de pièces nécessaires et est coordonné aux piles multicouches sur mesure afin de former un stratifié composite thermoplastique intégré pouvant présenter des zones de 10 épaisseurs différentes.
