Abstract: A constituent for producing a shock-absorbing composite material comprises 50-80 wt % primary matrix including vinyl acetate; ethylene/vinyl acetate copolymer; 10-40 wt % secondary matrix including polyethylene; styrene-butadiene rubber; a thermoplastic elastomer; and 1-20 wt % additive. A shock-absorbing composite material which contains the constituent and a production method thereof are further introduced. The shock-absorbing composite material is applicable to sports equipment (say, shoe pads, clubs and rackets), medical care (say, care-oriented clothes for the elderly, the sick, the injured, and the handicapped), and applications related to impact protection (say, helmets and bumpers.) The shock-absorbing composite material is applied to defense industry.

Abstract: The present invention provides an anti-shock pad, which includes: a board-shaped compound material structure, manufactured by mixing a composition and foam molding the composition, wherein the composition comprises: a main substrate, having a proportion of 50 wt % to 80 wt % of total weight of the composition, comprising: a vinyl acetate; and an ethylene-vinyl acetate; a secondary substrate, having a proportion of 10 wt % to 40 wt % of the total weight of the composition, comprising: a polyethylene; a styrene butadiene rubber; and a thermoplastic elastomer; and an additive, having a proportion of 1 wt % to 20 wt % of the total weight of the composition; wherein a density of the anti-shock pad is between 0.20 and 0.50, and a foaming ratio of the anti-shock pad is between 20 and 40. The present invention is also related to a method of manufacturing the anti-shock pad.
