| titleOfInvention | Method for producing molded body maintaining isotropic property |
| abstract | The present invention provides a molded article that is lightweight and has a degree of freedom in shape and maintains isotropy made of a fiber-reinforced composite material. A random mat is composed of a reinforcing fiber having a fiber length of 10 to 100 mm, a reinforcing fiber having a weight of 25 to 3000 g / m 2 and a thermoplastic resin, and occupying a reinforcing fiber bundle composed of more than the critical number of single yarns of the formula (1). The ratio is 30 or more and less than 90 Vol%, and the average number of fibers (N) in the reinforcing fiber bundle satisfies the formula (2). The prepreg 1 made of this random mat is placed in a mold comprising the cavity 2 and the cavity edge 3 with a charge rate of 50% or more and less than 90% in the formula (3), and the pressure is set to 1. after press molding at a predetermined temperature and pressure. After the pressure is increased to 2 to 25 times, it is cooled to a predetermined temperature or lower and molded. (1) Number of critical single yarns = 600 / D, (2) 0.7 × 10 4 / D 2 <N <6 × 10 4 / D 2, D; average fiber diameter (μm), (3) charge rate (%) = 100 × Base material area / mold cavity projected area, both projected area in the pulling direction (mm2) [Selection] Figure 1 |
