  A composite member comprising a thermoplastic resin and a rubber directly and firmly adhering to each other is rendered to be obtained. A composite member is obtained by adhering a molded element of a thermoplastic resin comprising a homo- or co-polymer of a vinyl cyanide including acrylonitrile, and a rubber molded element comprising a rubber composition containing a vinyl cyanide as a comonomer by means of heating. The resin molded element may be formed from, for example, AS resin, ABS resin or an polymer alloy containing ABS resin. The rubber molded element may be composed of a vulcanizable rubber composition comprising NBR or other rubber. Both the molded elements can adhere to each other by contacting the resin molded element with the rubber molded element closely and heating at least either the resin molded element or the rubber molded element by means of melting, vulcanization or the like.

  一种复合材料构件由热塑性树脂和橡胶直接牢固地粘合而成。 通过加热粘合热塑性树脂模塑件（包括丙烯腈在内的乙烯基氰化物的均聚物或共聚物）和橡胶模塑件（包括以乙烯基氰化物为共聚单体的橡胶组合物），可获得复合材料构件。树脂模塑元件可由 AS 树脂、ABS 树脂或含有 ABS 树脂的聚合物合金等材料制成。橡胶模塑元件可由丁腈橡胶或其他橡胶组成的可硫化橡胶组合物构成。将树脂模塑件与橡胶模塑件紧密接触，并通过熔化、硫化或类似方式加热树脂模塑件或橡胶模塑件，可使两个模塑件相互粘附。
