Problems solved by technology
Therefore, in the design stage, it is necessary to analyze the function of each component, and achieve the smallest volume and weight under the condition of meeting the performance index, especially for the superstructure of the underwater vehicle, because the volume and weight of the superstructure are designed to be large. Not only will the overall weight increase, but the sailing speed will also be reduced, and the flexibility of sailing will also be restricted and limited.

Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] This embodiment provides a mast made of high temperature and impact resistant composite materials, figure 2 Shows where this mast would fit on the underwater vehicle. The mast is the channel for the internal power source of the underwater vehicle to discharge exhaust gas, and also serves as the installation platform for the communication antenna base. In the present embodiment, the total length of the mast is 5m and the diameter is 150mm. Most of the mast moves with the aircraft under the water surface during work. During the movement of the aircraft, it is required that the mast can still work normally under the condition of bearing a certain impact force and the internal 250°C airflow; at the same time, its weight should be minimized under the condition of satisfying the strength and rigidity of use.

The invention discloses a high temperature-resistant impact-resistant composite material housing, and a molding method thereof. The high temperature-resistant impact-resistant composite material housing comprises an inner housing, a thermal insulation layer, a composite material layer and protection rings; the inner housing is a stainless steel thin-walled cylinder; the outside of the inner housing is successively covered with the thermal insulation layer and the composite material layer; the composite material layer comprises twill fabric and aramid fabric, wherein the periphery of the thermal insulation layer is covered by the twill fabric and the periphery of the twill fabric is covered by the aramid fabric; and more than two protection rings are uniformly arranged on the periphery of the composite material layer along the axial direction. According to the molding method, physical and chemical methods are combined, a novel multiphase solid material is made from a plurality of materials with different performances or functions, so that the high temperature-resistant impact-resistant composite material housing can be used with reliability under a high temperature of 250 DEG C, and no obvious deformation is caused. Because of appropriate structure design, and the composite material made from the materials with different hardness, integral strength and rigidity of the high temperature-resistant impact-resistant composite material housing are improved, and a certain degree of impact resistance is obtained.
Description
technical field [0001] The invention relates to a composite material shell and a forming method thereof, in particular to a high temperature-resistant and impact-resistant composite material shell and a forming method thereof. Background technique [0002] In order to safeguard the national maritime strategic rights and interests, it is imperative to develop high-tech marine equipment for both military and civilian use. From the analysis of the development situation at home and abroad in recent years, it is very important to develop a kind of equipment that can set the depth underwater and have the ability to detect dangerous waters or strike dangerous underwater targets. [0003] In addition, with the advancement of science and technology, the means of modern detection and interference, reconnaissance and anti-reconnaissance are becoming more and more mature. In order to ensure national maritime sovereignty, it is necessary to develop a While detecting and reconnaissance, ...
