摘要:
An object of the present invention is to provide a curable resin composition capable of giving a cured product which is excellent in mechanical properties (such as elastic modulus) and toughness. The curable resin composition contains 60 to 99 parts by mass of an unsaturated ester resin, 0.5 to 20 parts by mass of an epoxy resin, and 0.1 to 20 parts by mass of crosslinked rubber particles having a number average particle diameter of 20 nm to 600 nm. The crosslinked rubber particles are obtained by polymerizing a vinyl monomer in the presence of one or more rubber polymers selected from the group consisting of a butadiene rubber, a butadiene-styrene rubber, a butadiene-butyl acrylate rubber, a butyl acrylate rubber and an organosiloxane rubber.

The present invention provides a reinforcing structural rebar. The rebar comprises an inner core formed by pultruding reinforcing fibers through a bath of a first resin material, the inner core typically containing at least about 40 percent by weight reinforcing fibers and an outer cladding of a corrosion resistant and reinforced second resin material.
摘要:
A formable prepreg, and a method of making a formable prepreg by a pultrusion process. The method includes (a) impregnating reinforcing fiber with a thermosetting resin matrix, and (b) passing the resin impregnated reinforcing fiber through a die within which the resin impregnated reinforcing fiber is subjected to conditions sufficient to thicken the thermosetting resin matrix, to provide a formable prepreg. The present invention also provides a method of making a molded article using the prepreg of the present invention.
