Thermoplastic continuous fiber prepreg braided rope hot melt wound bellows and fabricating equipment thereof

Abstract

The invention relates to the field of strengthening a polymer compound with a loose or adherent fibrous material, in particular to a thermoplastic continuous fiber prepreg braided rope hot melt woundbellows and fabricating equipment thereof. The thermoplastic continuous fiber prepreg braided rope hot melt wound bellows is characterized in that a hot melt wound bellows (10) is composed of a plastic inner layer pipe (11) and the outer wall of the plastic inner layer pipe (11) continuously winding a thermoplastic continuous fiber prepreg braided rope. Mechanical strength is high, and the servicelife is long.

Description

technical field [0001] The invention relates to the field of reinforcing polymer compounds with loose or adhered fibrous materials, in particular to a hot-melt winding bellows of thermoplastic continuous fiber prepreg braided rope and its manufacturing equipment. Background technique [0002] With the continuous expansion of the scale of urban construction at home and abroad and the expansion of rural urbanization, the use of pipe networks for receiving urban, urban, and rural rain and sewage pipes is increasing, and the diameter of pipes is also increasing. The deeper the pipeline, the higher the strength of the pipeline, so a large number of high-quality sewage pipelines are needed to support the drainage of rainwater and sewage in cities and towns. [0003] In the domestic market, most of the existing rain and sewage pipes are made of plastic corrugated pipes or plastic and metal composite pipes such as steel belt reinforced corrugated pipes. Since the materials used to m...

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
