- the present comparative example is an example of producing a formed plate using a normal carbon fiber non-woven fabric instead of the chopped strand 'pre-preda. It was preheated to 260 to 280 ° C by a far-infrared heater using a carbon fiber reinforced stamper sheet in which carbon fiber HTA-12K (800 tex, 12,000 strands, Toho Tenax Co., Ltd.) non-woven fabric and PA6 are integrally laminated. Thereafter, heat and pressure treatment was carried out using a mold press method under conditions of 80 to 120 ° C. to obtain a molded plate of 3 mm in thickness.
- the mechanical properties are as shown in Table 1.
- the fiber volume content is the same as in Example 1 of the present invention.
- the force mechanical properties are found to be superior to that of the present invention.
- Example 1 In this comparative example, in place of the chopped strand 'pre-preda, the same chopped fiber of carbon fiber (length 6 mm) and PA6 resin pellet as in Example 1 are used for injection molding according to a conventional method and molded into a thickness of 3 mm. The board was manufactured. The mechanical properties of the obtained molded plate are as shown in Table 1. The fiber volume content is the same as that of Example 1 of the present invention, but it is understood that the mechanical physical property values are better in the present invention.
- the fiber-reinforced thermoplastic resin sheet of the present invention and a molded plate obtained therefrom are excellent in physical properties such as strength and elastic modulus, and their physical properties are isotropic, so FRP molded articles of various shapes are obtained. It is suitable as a material for molding.
