Embodiment Construction
[0022] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0023] According to typical embodiments of the present invention, such as figure 1 As shown, the internal thread holes in the body of the connector and the connector are pre-embedded. Applying the technical scheme of the present invention, the threaded holes are pre-processed on the inner wall of the pipe fittings with suitable size and shape. After the composite material is impregnated, the subsequent processing and punching process can be omitted, which facilitates the connection of the composite material with other parts and improves the connection efficiency of the composite material. Bearing performance, eliminating the weakening of the performance of the composite material by machining, re...

The invention relates to a three-dimensional composite material weaving method and product thereof of an embedded connecting member. The three-dimensional composite material weaving method comprises the steps of: determining a size and an arrangement manner of a guide sleeve in a prefabricated member according to characteristics of appearance size, structure and the like of a workpiece required to be prepared; determining a size and an arrangement manner of an auxiliary guide sleeve according to characteristics of diameter, height and the like of the embedded connecting member in a region reserved in a position of the connecting member; arranging the guide sleeve, the auxiliary guide sleeve and the connecting member on a mould plate according to the design, performing glue preventing treatment on the connecting member in the prefabricated member; selecting corresponding wires according to the requirement of the workpiece, laying the wires based on the mould plate with the guide sleeve and the connecting member to obtain the prefabricated member; and impregnating the prefabricated member subjected to sealing treatment through the connecting member in a base body for forming to obtain the required three-dimensional weaving composite material product of the embedded connecting member. When the composite material is connected with other parts, the composite material is fixed on other parts through the embedded connecting member by using a screw, and is very conveniently disassembled or assembled.
Description
technical field [0001] The invention relates to the field of composite materials, in particular to a composite material product with a special structure that is convenient to be connected with other components. Background technique [0002] In recent years, natural resources have been gradually scarce, and the production and transportation costs of the material manufacturing industry have increased year by year. Therefore, research on material lightweight technology is the focus of many scientific researchers, especially in aerospace, automotive, petrochemical and other fields. On the basis of ensuring the basic performance requirements of materials, reducing the weight of materials used can greatly reduce production and transportation costs. Composite materials are widely used in various fields due to their advantages of light weight, high strength, good fatigue resistance, corrosion resistance and material design. [0003] Many achievements have been made in the research ...
