Kind Code:
A1
Abstract:
A forming device for a continuous fiber reinforced composite pipe, relating to the technical field of composite pipelines, and comprising a forming mold (1) and an outer pipe (2), wherein a forming cavity channel (1c) is formed between an outer mold sleeve (1a) and a core mold (1b) of the forming mold (1); one end of the outer pipe (2) extends into the outer mold sleeve (1a) from the front port of the outer mold sleeve (1a); an annular cavity channel (1d) through which fibers pass is formed between the outer circumferential wall of the outer pipe (2) and the inner circumferential wall of the outer mold sleeve (1a); a cylindrical supporting cylinder (1e) sleeved outside the core mold (1b) is arranged in the forming cavity channel (1c); material passing holes (1e1) are formed on the supporting cylinder (1e) in a distributed mode; a gap is formed between the outer circumferential wall of the supporting cylinder (1e) and the inner circumferential wall of the outer mold sleeve (1a); and a feeding channel used for injecting a molten material into the supporting cylinder (1e) is further formed in the outer pipe (2). According to the present forming device for the continuous fiber reinforced composite pipe, a composite pipeline produced by the forming device has the advantages of being high in strength and good in toughness.
