Abstract: A multiaxial textile resin base material comprising a thermosetting resin (B) impregnated in a multiaxial textile base material laminate. The multiaxial textile base material laminate includes fiber bundle sheets in which a unidirectionally aligned fiber bundle is stitched by a stitching yarn composed of a thermoplastic resin (A), the fiber bundle sheets being stacked at different angles, and is traversed in the thickness direction by the stitching yarn that is separate from the laminate, wherein the stitching by the separate stitching yarn runs back and forth while being disposed at a predetermined interval along the length direction. The thermoplastic resin (A) constituting the stitching yarn has a softening point, and the softening point is higher than a resin impregnation temperature for the thermosetting resin (B). Provided is a multiaxial textile resin base material that has an excellent resin impregnability, a high durability (hydrolysis resistance, resistance to thermal deterioration), excellent mechanical properties for composite materials, and an improved compression-after-impact (CAI).

Abstract: This fiber-reinforced polymer alloy substrate, in which continuous reinforcement fibers are arranged in parallel and are impregnated with a polymer alloy, is characterized in that: a polymer alloy obtained by combining thermoplastic resins of at least two types is used as the polymer alloy; the fiber volume content ratio is in the range 40–70% by volume; and the dispersion parameter D of the fibers is at least 90%. In the obtained fiber-reinforced polymer alloy substrate, the reinforcement fibers are dispersed with high homogeneity, and mechanical characteristics and heat resistance are high and expressed stably with low variation.

Abstract: A fiber-reinforced resin base material which is obtained by impregnating a continuous reinforcing fiber or a reinforcing fiber material, wherein discontinuous fibers are dispersed, with a resin composition that has a single glass transition temperature before and after one-hour heating at 400°C, and which is configured such that the resin composition is composed of (A) a thermoplastic resin that has a glass transition temperature of 100°C or more and (B) a thermoplastic resin that has a glass transition temperature of less than 100°C. Consequently, the present invention provides a fiber-reinforced resin base material which exhibits excellent impregnation ability and thermal stability, while having few voids, thereby achieving good surface quality and high heat resistance.
