Thermoplastic continuous fiber prepreg braided rope hot-melt winding corrugated pipe and its manufacturing equipment

Abstract

The invention relates to the field of reinforcing polymer compounds with loose or adhered fibrous materials, in particular to a thermoplastic continuous fiber prepreg braided rope heat-melt winding corrugated pipe and its manufacturing equipment. A thermoplastic continuous fiber pre-impregnated braided rope hot-melt winding corrugated pipe, characterized in that: the hot-melt winding corrugated pipe (10) is made of a plastic inner layer pipe (11) and the outer wall of the inner layer pipe (11) is continuously wound with thermoplastic continuous fiber prepreg Braided rope (12) forms. The invention has high mechanical strength and long service life.

Description

Technical field[0001]The present invention relates to the field of reinforced polymer compounds with loose or adhered fibrous materials, and is specifically a thermoplastic continuous fiber prepreg and a thermal melt winding ripple and its manufacturing equipment.Background technique[0002]With the expansion of domestic and foreign urban construction, the scale of rural urbanization is expanded, as the use of pipe networks emissions from urban, urban rainwater pipelines is getting bigger and bigger, and the pipe diament is getting bigger and bigger, and the buried The wearer is getting higher and higher, so a large number of high-quality sewage pipes are required to support urban rain sewage emissions.[0003]In the domestic market, most of the existing rain sewage tubes are all plastic bellows or plastics and metal composite pipes such as steel strips, because the material of the material to produce plastic bellows is not high, it is necessary to pass structural design. Increase the h...

Problems solved by technology

However, when the fiber bundles in the monofilament state are aggregated together, the fiber bundles in the dispersed and free state will produce self-friction on the surface of the fiber to produce micro-cracks and then reduce the cross-section and reduce the tensile strength under the condition of shaking and fluctuation. Therefore, the monofilament fiber The surface of the material has not been pre-impregnated with plastic, and the long-term use has a tendency to reduce the strength of the pipeline, resulting in a decrease in the strength of the pipe. Therefore, the original inorganic fiber tow cannot be directly used as a reinforcing material for the manufacture of products.

[0005] In view of the above problems such as low strength of plastic materials, easy separation of steel belt reinforcement, and short service life of original inorganic tow reinforcement, the present invention solves the problems of low strength of plastic materials, easy separation of steel belt reinforcement, and original inorganic tow reinforcement through material design and structural design. The problem of short lifespan
