    • A process for producing a composite plastic pipe, which comprises producing a thermoplastic resin pipe (I) by an extruder, covering the surface of the pipe (I) uniformly with a continuous fibrous reinforcing material (II) impregnated with a thermosetting resin in its axial direction by a draw molding method, helically winding a continuous fibrous reinforcing material (III) impregnated or not impregnated with a thermosetting resin uniformly on the layer of the resin fibrous reinforcing material (II) by a filament winding method, thereafter curing the thermosetting resin by irradiation of ultraviolet light and coating a thermoplastic resin (IV) on the resulting product within a crosshead die in an extruder.
    • 一种复合塑料管的制造方法,其特征在于,包括通过挤出机制造热塑性树脂管(I)的方法,在其轴向上用浸渍有热固性树脂的连续的纤维增强材料(II)均匀地覆盖管(I)的表面 通过拉伸成型方法,通过丝线缠绕法将浸渍或未浸渍有热固性树脂的连续纤维增强材料(III)螺旋缠绕在树脂纤维增强材料(II)的层上,然后通过纤维缠绕法将热固性树脂固化 照射紫外线并在挤出机中的十字头模具内将所得产品涂覆在热塑性树脂(IV)上。
