Title:
METHOD FOR LAMINATING FIBER-REINFORCED THERMOPLASTIC RESIN PREPREG
Document Type and Number:
WIPO Patent Application WO/2011/125596
Kind Code:
A1
Abstract:
Disclosed is a method for achieving lamination of the near net shape of a molded article which has a high yield of material and is strong and rigid. The near net shape of the molded article is sewn using prepreg tapes (1) which are composite materials composed of reinforced fibers and thermoplastic resin. For the strength and rigidity as the molded article, the prepreg tapes (1) the directions of the fiber arrays of which are different are arranged within one layer in consideration of the directions of the fiber arrays and the direction of an external force. Moreover, performed is a stitching method wherein the stitching manner is varied while attaching the prepreg tapes (1), thereby sewing the near net shape of the molded article consisting of a multilayer structure.
