Abstract: The present invention provides a carbon-fiber reinforced thermoplastic resin (CFRTP) having excellent adhesion between a carbon fiber, used therein as a reinforcing material, and a thermoplastic resin, used therein as a matrix. A carbodiimide agent is employed in order to achieve the above object. By the present invention, the carbodiimide agent is adhered to a carbon fiber for a reinforcing material, and the thus-treated carbon fiber is combined with a matrix thermoplastic resin; or the carbodimide agent is mixed with a matrix thermoplastic resin, and the mixture is combined with a carbon fiber for a reinforcing material. The carbodiimide agent enhances adhesion between the carbon fiber and the matrix thermoplastic resin. Accordingly, superior mechanical properties of the carbon fiber is sufficiently exploited in the CFRTP produced according to the present invention; therefore, the CFRTP of the present invention is an excellent composite material having superior mechanical strength.

Abstract: In composition of a copolymer making up a fitting pad for ski boots containing, as the major component, vinyl acetate, an acrylic component and ethylene, the content ratio of components other than ethylene is 20% or larger and the average molecular weight is 30,000 or smaller. The specified content ratio of the component other than ethylene and average molecular weight results in good fitness to a skier's foot thanks to good fluidization of the fitting material during application process, thereby assuring painless use even for a long period and good transmission of the movement of the skier's leg to the ski.
