The present invention is to provide a resin composition having sufficient rigidity and superior in the workability as well even if the thickness is as thin as 0.2 mm or less, and a prepreg and a laminate obtained from the resin composition. The resin composition comprises resin component containing a (A) compound having a maleimide group and (B) calcinated talc, wherein the calcinated talc is contained not less than 30 weight parts and not more than 250 weight parts to 100 weight parts of the total amount of the resin component containing a (A) compound having a maleimide group.

Resin composition, prepreg and laminate using the composition

A paved road including a reinforcement sheet layer (A) and a pavement layer (), in which the reinforcement sheet layer (A) includes an asphalt layer () laminated to at least one side of a reinforcement sheet () including a composite material that is impregnated with a thermoplastic resin to achieve a volume content of a continuous glass fiber, which is a reinforcement fiber, of not less than 30% and not moere than 85% is proved.

Road reinforcement sheet, structure of asphalt reinforced pavement and method for paving road

The invention provides a laminated product of urethane-based resin. That is, the invention arranges a continuous reinforcing fiber to one direction, impregnates the arranged fiber with thermoplastic resin to form a prepreg sheet having 50% in volume ratio of the fiber, laminates two or more resulting prepreg sheets so as to intersect fiber directions at right angles or further laminate of the prepreg sheet to form a fiber-reinforced resin layer, laminates a urethane-based resin layer on the resulting fiber-reinforced resin layer, and thus provides a urethane-based resin laminated product having excellent dimensional stability and application ability.

Laminated product

A waterproof material is disclosed herein which is obtainable by laminating many sheets of a photo-setting type fiber reinforced thermosetting resin composition comprising a resin composition containing a thermosetting resin, a photopolymerization initiator and a thickener, and a fiber reinforced material, or by laminating plural sheets of a synthetic polymer, and a waterproof application method using the waterproof material is also disclosed herein. According to the present invention, the waterproof layer can be formed on the surface of a civil engineering works or a building in a short time of about 30 minutes by a few steps without polluting a working environment. Furthermore, the waterproof layer, needless to say, has water resistance, weathering resistance, anticorrosion and substrate adhesion. In addition, it is further excellent in follow-up properties to cracks of the substrate, and walking on the waterproof layer is possible.
