1. Prepregs are continuously laid up on a carrier sheet such as backing paper, and the laid-up prepregs are wound into a roll form to manufacture a single-ply axial UD roll.
2. Prepregs are laid up in multiple layers at the required angles, and the laid-up prepregs are wound into a roll form to manufacture a multi-ply/multi-axial UD roll.
3. Use of angle UD rolls in the lay-up process allows a simplified lay-up of angle layers.
Effect(s)
Less material scrap generation
Cost reduction by simplification of the lay-upmachine
Reduction of the lay-up cycle time
・Mass production line for long structural parts for aircrafts
・Use of axial UD rolls as the sheet winding molding materials for cylindrical molded parts
Technical Problems
Axial UD roll is produced off-line (out of manufacturing line) and supplied as base material to the manufacturing line process.Establishment of a supply chain for manufacturing and selling axial UD rolls
Collaborator needed to Improve
Companies and research institutions including universities having the know-how about molding andprocessing of CFRP materials
