摘要： PURPOSE:To obtain a reinforced plastic molding with excellent mechanical characteristics (bending strength, bending elasticity, impact resistance, wear resistance, high temp. elasticity, etc.,) by making a reinforced fiber impregnated with a thermoplastic resin so as to be impregnated substantially into single fiber level and arranging it in a pellet in a form of a specified filament product. CONSTITUTION:A rod-like molding wherein a fiber bundle is impregnated with a polymer and integrated with the polymer into a body by heat-compression is then compressed while it is cooled. The obtd. rod-like molding is cut into a length of 3-100 mm to make a pellet-like molding. The content of the reinforcing fiber is 5-70 wt.% and a twist index obtd. by measuring a twist angle theta(radian) of the filament product of the remaining reinforced fiber taken out of the molded material by either dissolving the matrix resin of the molded material with a solvent or burning, is made in a range of 0.015 or larger and 0.24 or smaller. The reinforcing fiber in the molding thereby entangles effectively and forms an integrated structure over the whole molding to improve impact resistance.

摘要： PURPOSE:To provide the title pellet-shaped form improved in resistance to impact and fatigue etc., usable for injection molding, with long reinforcing fiber homogeneously dispersed in the matrix polymer. CONSTITUTION:The objective pellet-shaped form with a thermoplastic polymer as matrix, containing 30wt.% of parallel-arranged reinforcing fiber with its length of 3-60mm. Furthermore, said form is >=20% in mixing dispersion rate and 5-80 in microvoid density index. To obtain said form, for example, combined yarn comprising fiber made from the thermoplastic polymer and the reinforcing polymer is heated to a temperature higher than that where said thermoplastic polymer fiber is melted and allowed to flow, and, in this state, the resultant yarn is put to e.g. roll compression.

摘要： PURPOSE:To manufacture a tough molded product of high dynamic rigidity by heating a cloth consisting of mixed yarns of reinforced fiber and thermoplastic resin fiber under reduced pressure and compression molding the same at the temperature where the thermoplastic resin fiber is melted and fluidized. CONSTITUTION:As an example of a particularly favorite thermoplastic resin fiber, a so-called polyethylene terephthalate partly oriented resin yarn is used. As for the reinforced fiber, for example, a continuous system of carbon fiber, glass fiber, aramid fiber or the like is used. For the purpose of removing air contained in the cloth, the pressure of the whole of a molding machine can be reduced, or only the pressure inside a mold can be reduced. Pressure reducing can be carried out before heating the cloth or while the heating is applied up to the temperature region to soften the fiber constituting the cloth, or else while heating is applied to the melting temperature region, and above all, it is desirable to heat to the temperature of softening point or lower and reduced pressure while the shape of the cloth is maintained in order to remove the air effectively.
