Point of the Proposed Technology
・CFRTP part can be molded directly from the textile base material, and no manufacturing process of CFRTP prepreg is required.
・It can be woven by a general-purpose weaving machine, and it can apply to various weaving conditions corresponding to needs at low cost.
・Since the textile base material has a plasticity, it easily follows to the molding die and can be used for a complicated three-dimensional molding.

Effect(s)
・15% reduction of material cost
・Good three-dimensional moldability
・Good three-dimensional moldability
Conventional Technology
◇Conventional CFRTP parts manufacturing process
・Two hot press processes, in prepreg manufacturing and parts manufacturing, are required.
・Since prepreg is a plate material, it is difficult to mold into a complicated three-dimensional form.

| Example of Application | ・Parts for automobiles and aircrafts
・Enclosures for OA equipment and medical devices | ||||
| Technical Problems | ・Optimization of composite yarn manufacturing conditions (proportion of fiber and resin, etc.)
・It is molded directly from textile (raw material), and therefore, a high molding pressure (about 20 MPa) is needed to impregnate carbon fiber with resin. ・Sale as a material (textile base material) has been under consideration. | ||||
| Collaborator needed to Improve | ・Processing manufacturers having expertise in CFRTP three-dimensional molding
・Institutions including universities having CFRTP performance assessment technologies/equipment | ||||
