Title:
MANUFACTURE OF FIBER-REINFORCED THERMOPLASTIC RESIN TUBE
Document Type and Number:
Japanese Patent JPH0516262
Kind Code:
A
Abstract:

PURPOSE: To obtain a product having excellent pressure resistance, shock resistance and dimensional accuracy by using a thermoplastic resin as a synthetic resin, mounting an inner core projected in the direction of extrusion from the resin outlet of a mold and manufacturing a fiber-reinforced synthetic resin in the manufacture of the fiber-reinforced synthetic resin tube.

CONSTITUTION: A thermoplastic resin melted from an extruder 3 is fused and laminated on the inner surface of a sheet-shaped fiber composite body A1 while the composite body A1 is transferred continuously between an inner mold 2 and an outer mold 7 and a two layer tube is formed, a tape-shaped fiber composite body C1 is wound spirally at a position corresponding the outer-surface inner core 6c of the two layer tube, and heated and fused and laminated, and the composite body C1 is taken up continuously by a cooler 14 and a take-up unit 15, thus manufacturing a three layer tube P1. Accordingly, when the tape- shaped fiber composite body C1 is wound, the deformation of a thermopolastic resin inner layer B2 can be prevented by the winding force.
