Abstract

The invention relates to a high-strength fiber weaving, winding, pulling and extruding pipeline and a production technology thereof. The production technology of the pipeline comprises an inner-layer braiding machine (1), a glue spraying region (2), an outer-layer braiding machine (4), a glue dipping tank (5), a thermal curing mould (6), a traction machine (7), a cutting machine (8) and a mould core (9). The high-strength fiber weaving, winding, pulling and extruding pipeline comprises an outer braid layer (10), a middle layer (11) and an inner braid layer (12). The production technology of the pipeline is characterized by also comprising a lap joint nail spraying region (3), and the lap joint nail spraying region (3) is arranged between the glue spraying region (2) and the outer-layer braiding machine (4). The high-strength fiber weaving, winding, pulling and extruding pipeline and the production technology thereof have compression resistance, bending resistance and internal pressure resistance, also have stronger tear resistance and impact resistance and are wide in application range.

Description

Technical field [0001] The invention relates to a high-strength fiber braided pultruded pipe and its production process. It belongs to the field of pipeline production technology. Background technique [0002] Existing fiber braided pultruded pipes are generally cylindrical or rectangular pipes. The surface of the pipe is smooth. The pipe has a multi-layer fiber structure. The inner and outer surface layers are covered by fiber woven fabric. There are multiple longitudinal or circular distributions in the middle. The fiber layer. [0003] The performance indicators of fiber braided pultruded pipes mainly include the following five: 1. Compression resistance; 2. Bending resistance; 3. Internal pressure resistance; 4. Tear resistance; 5. Impact resistance, of which tear resistance Cracking performance refers to the parameter that the pipe is not easy to tear in the axial direction, and the impact resistance refers to the parameter that the pipe is not easy to peel off in the radial...
