Abstract: The phenolic resin composition for fiber-reinforced composite materials of the invention comprises at least the following constituent elements A and B of a thermoplastic resin: A: phenolic resin, B: at least one thermoplastic resin selected from polyvinyl formals, polyvinyl acetals, polyvinyl butyrals, polyvinyl pyrrolidones, polyvinyl acetates, polyvinyl alcohols, polyethylene glycols, copolymerized nylons and dimer acid polyamides. The resin composition is filmwise applied to reinforcing fibers, and the resulting film is heated under pressure whereby it is impregnated into the reinforcing fibers to give a prepreg for fiber-reinforced composite materials.

Abstract: The present invention relates to a carbon fiber prepreg. The carbon fiber prepreg of the present invention is characterized in that a carbon fiber bundle comprising a plurality of continuous carbon filaments and having a hook drop value of 10 cm or more as the degree of fiber entanglement is impregnated with a base resin mainly composed of a thermosetting resin, and that particles of 150 mu m or less in particle size made of a thermoplastic resin account for 20 wt% or less based on the weight of the entire prepreg and distributed at a higher concentration in the surface zone than in the inside. The carbon fiber prepreg of the present invention is good in tackiness and less changing in tackiness with the lapse of time, and can form a composite with an excellent compression interlaminar shear strength (CILS) at high temperature after moisture absorption while maintaining good impact resistance. It also allows the production of a composite very higher than the conventional composite in the compressive strength (LCS) of a cross laminated panel. The carbon fiber prepreg of the present invention can be preferably used as a structural member in such areas as aerospace area, sporting area and civil engineering and architecture area.

Abstract: PROBLEM TO BE SOLVED: To improve the usability of a heat insulation sheet material by applying a resin compound containing inorganic hollow particles on a reinforcing base member. SOLUTION: A resin compound 1 containing inorganic hollow particles is applied on a reinforcing base material 2 of 1-60 wt.% in the content ratio to form a laminate body for this heat insulation sheet material. The applied thickness of the resin compound 1 is made uniform to have a substantial thickness of 0.3-50 mm by using a knife having a constant distance from a substrate plate to regulate the applied thickness. Since the inorganic hollow particles have a heat insulation property by itself and hence, when the particles are mixed with a resin component at a specified ratio, the heat insulation property is enhanced. Wide usability, heat-resistance property, and cost can be improved by using the reinforcing base material 2 composed of inorganic or organic fiber. In this way, it can be easily handled in a construction site. When stuck on architectural members, the heat insulation property and the reinforcing performance of the architectural member can be greatly improved.

Abstract: PROBLEM TO BE SOLVED: To obtain a prepreg having good tack with little deterioration with the lapse of time, and capable of giving a fiber-reinforced composite material excellent in compressive interlaminer shear strength(CILS) and a cross laminate compressive strength(LCS) at a high temperature after moisture absorption while keeping its impact resistance. SOLUTION: This prepreg is produced by impregnating a resin satisfying a requirement (B) in carbon fiber satisfying a requirement (A). In this prepreg, particles satisfying a requirement (C) exist not more than 20%, and they are distributed on the surface in higher concentration than inside the prepreg. Requirement (A): Carbon fiber with a tensile strength not less than 4,400MPa consisting of continuous fiber having a hook-drop value not less than 10cm. Requirement (B): A base resin consisting mainly of a thermosetting resin. Requirement (C): Particles with each size not more than 150μm consisting of a thermoplastic resin.
