Abstract: This structural material is composed of a polyamide resin reinforced by a reinforcing material composed of continuous filaments and/or long fibres. The reinforcing material is surface-treated with a surface-treatment agent for nylon, soluble in alcohol and/or water. The specific viscosity (eta) of the polyamide resin is more than 1.8 poise. The amount of reinforcing material used is 10-80 wt.% of the polyamide resin. The structural material is shaped as a stick or a tennis racket. The structural material is produced by means of a polymer casting method composed of the following processes: (1) The surface treated fibrous reinforcing material is arranged in a specific shape. (2) The arranged material is placed in a mould. (3) A molten omega-lactam containing a polymerisation catalyst and an initiator is introduced into the mould. (4) The reinforced polyamide resin is obtained by heating the mould.
