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.
