Abstract: A laminar reinforcing structure is provided for impact resisting face on an article, such as toe-puffs of safety shoes, striking faces on baseball bat and ice hockey stick, outsoles for boots of ice skates, and heads or faces of golf clubs, to increase an impact-resistant strength at such faces. The reinforcing structure includes a basic layer and at least one reinforcing layer. The basic layer is made of one or more plies of a fiber-reinforced thermosetting resin material and molded into a profile matching with that of the impact-resisting face of the article. The reinforcing layer is made of a thermoplastic resin-fiber woven fabric dip-coated with thermosetting resin to cover at least part of surfaces of the basic layer or be sandwiched between any two adjacent plies of the basic layer. The laminar reinforcing structure provides excellent mechanical strength and has low weight without substantially increasing the article weight.

Abstract: A board for sporting purpose, such as a skateboard or a surfboard, includes an upper and a lower layer, and an intermediate layer sandwiched between the upper and lower layers. The intermediate layer is formed from a plurality of elongate supporting members that extend in a longitudinal or moving direction (Y-direction) of the board and are horizontally and parallelly arranged in a transverse direction or X-direction of the board. Each supporting member has a cross section of suitable shape and dimensions, and is coated over all outer surfaces with a layer of fibrous fabric, making the whole intermediate layer a light and three-dimensionally reinforcedg layer for the board, so that the board has increased rigidity and torsional strength and reduced weight in unit thickness to provide upgraded quality for use.
