摘要： A laminate for forming a composite material is provided. The laminate has a structure in that unidirectional yarn sheets S in which yarns are arranged in parallel to each other in one direction without bending and thermoplastic resin films F are alternately stacked so that the film F is located between the unidirectional yarn sheets S. The yarn sheets S and the films F having a degree of crystallinity XC of 30% or less are integrally coupled by stitching yarn Y, and adjacent unidirectional yarn sheets S are obliquely stacked at an angle of ±1° to ±90° to a direction in which yarns included in the respective unidirectional yarn sheets S are arranged. The use of unidirectional yarn sheets S, instead of fabrics or multi-axial fabrics, achieves excellent smoothness. Composite material manufactured using the laminate has uniform physical properties such as strength.

摘要： A method for preparing a high quality thermoplastic prepreg, includes: laminating a thermoplastic resin film having a crystallization degree in a range of 1 to 20% on at least one surface of a matrix fiber; and heating the laminate to a higher temperature than a melting point of the film, then, pressing the same. The method uniformly impregnates a matrix fiber with a thermoplastic resin, has a short curing cycle in the formation, and involves no random modification in alignment of fibers in the matrix fiber due to a low crystallization degree of the impregnated thermoplastic resin, thereby increasing rigidity of a formed product and enabling reduction of thickness. Thus produced prepreg has a low weight variation per unit area.

摘要： A 0° unidirectional yarn prepreg and a preparation method are disclosed. The 0° unidirectional yarn prepreg has high-strength filaments which are arranged in parallel to each other in an axial direction X of a winding roller around which unidirectional yarn prepregs are wound and a resin is impregnated. The method includes steps of: (i) weaving a fabric using a thermoplastic film tape as a warp and using high-strength filaments as wefts; and (ii) performing thermal compression on the woven fabric at a temperature in which the warp is melted. Also, a multiaxial prepreg composite material is prepared by simultaneously and continuously supplying the 0° unidirectional yarn prepreg A prepared as described above method and a 90° unidirectional yarn prepreg B prepared by a conventional warping method to a thermal compression roller, and performing thermal compression thereon.

摘要： An intermediate material of a thermoplastic prepreg for a fuel cell separation plate comprises a hydrophobic thermoplastic resin film and a fiber base. The hydrophobic thermoplastic resin film has a degree of crystallization of 1 to 20%, a thickness of 3 to 50 μm, and (iii) a content of an electroconductive material of 1 to 20 wt. %. The film is laminated on at least one surface of the fiber base. The thermoplastic prepreg for a fuel cell separation plate is manufactured by pressurizing the thermoplastic prepreg intermediate material at a temperature higher than the melting point of the hydrophobic thermoplastic resin film. A fuel cell separation membrane manufactured using the thermoplastic prepreg intermediate material and thermoplastic prepreg is thin and light-weight, and have a good durability.
