ことができる。 The weaving structure is usually a plain weave, but it may be a twill weave or a satin weave, or it may be a triaxial weave or a bias weave in which the warp and weft are arranged diagonally with respect to the length of the fabric. It may be. The molding material of the present invention has carbon fiber multifilaments and PEEK monofilaments, multifilaments, or slit yarns lined up to form the warp and weft, so unlike the above-mentioned mixed woven fabric, during molding. Melting of the PEEK monofilament, multifilament or slit yarn does not cause the carbon fiber multifilament to become uninterlaced, ie, the carbon fiber multifilament weave to be woven.
That is, the carbon fiber multifilament still remains in the form of a fabric with excellent shape retention. Therefore, it is possible to prevent the carbon fiber multifilament from being swept away and moved or being bent significantly as the PEEK monofilament, multifilament, or slit yarn melts.

なる。(Effects of the Invention) The molding material of the present invention is made of a woven fabric in which carbon fiber multifilaments and polyetheretherketone monofilaments, multifilaments, or slit yarns are aligned to form warp and weft yarns. It has excellent drapability and flexibility, and conforms well to the mold even when molding CFRTP with complex curved surfaces. Therefore, not only is molding very easy, but also homogeneous CFRTP can be molded. Also, PEEK
has excellent thermal and mechanical properties, especially thermal properties, making it possible to obtain CFRTP with excellent heat resistance properties. Furthermore, since the carbon fiber content is 45 to 70% by volume, it
To prevent carbon fiber multifilaments from being washed away and moved or greatly bent as the PEEK monofilament, multifilament or slit yarn melts and the carbon fiber multifilaments are uninterlaced. Coupled with this ability, it becomes possible to obtain CFRTP with excellent mechanical properties such as strength and elastic modulus.
