Embodiment 1

[0032] like figure 1 As shown, the present embodiment provides a torpedo with a carbon fiber composite hood and its components that can reliably crack and reduce the load at a water entry speed of 50-300m / s, so as to solve the problem of the hood in the prior art under different water entry speeds. Reliable separation issues and buffer load shedding issues. The carbon fiber composite material cushioning load reduction head cover provided by the present invention includes: a carbon fiber composite material cover 100, a buffer load reduction assembly 200, a positioning ring 300 and a fixing assembly 400; the buffer assembly 2 is arranged in the carbon fiber composite material cover 100 and is located near the end position, the material is preferably PMI foam with high temperature resistance and high strength; a positioning ring 300 is installed between the buffer assembly 2 and the top of the torpedo; the positioning ring 300 is connected to the carbon fiber composite material c...

Embodiment 2

[0040] On the basis of the above-mentioned embodiments, the present invention further provides a method for preparing a carbon fiber composite cover, comprising the following steps:

[0041] The carbon fiber composite cover 100 is molded using a metal male mold. Lay all the carbon fiber fabric prepregs on different areas of the male mold according to the designed carbon fiber layup sequence. After laying the cloth layers, vacuumize and cure them in an oven at 160-180°C. After the hood is cured, process according to its design requirements. Its profile and internal fixing grooves.

[0042] After the processing of the carbon fiber composite material cover is completed, a layer of PTFE release cloth containing glue is pasted on the bottom of the buffer assembly 2, and then it is loaded into the head cover 1 so that it is tightly attached to the inner wall of the carbon fiber composite material cover, and then placed on the The mid-section of each sub-lobe of the carbon fiber com...

Abstract

The invention relates to the technical field of torpedo water entry buffer load reduction design, in particular to a carbon fiber composite buffering and load-reducing hood and a preparation method thereof. The carbon fiber composite buffering and load-reducing hood comprises a carbon fiber composite cover, a buffering and load-reducing assembly, a positioning ring and fixing assemblies. A buffering assembly is located at the position close to the end part of the carbon fiber composite cover and arranged in the carbon fiber composite cover; a positioning ring mounting groove is formed in the carbon fiber composite cover; the positioning ring is fixedly mounted in the positioning ring mounting groove; the tail end of the carbon fiber composite cover is cylindrical; a plurality of fixing assembly mounting grooves are formed in the cylindrical section part of the tail end of the carbon fiber composite cover; the fixing assemblies are fixedly arranged in the fixing assembly mounting grooves respectively; and the carbon fiber composite cover is prepared by performing high-temperature vacuum curing on a carbon fiber paving layer. By using the carbon fiber composite buffering and load-reducing hood and the preparation method disclosed by the invention, the technical problem how to reduce potential damage, caused by a water surface impact load, to internal components when a torpedo enters water is solved.

Description

technical field [0001] The invention relates to the technical field of torpedo water-entry buffer load reduction design, in particular to a carbon fiber composite material buffer load reduction head cover and a preparation method thereof. Background technique [0002] As one of the main components of the torpedo, the cushioning drop-down hood can effectively reduce the instantaneous impact load of the torpedo when it enters the water at high speed, reduce the internal damage and deformation of the torpedo, and effectively protect its internal electronic sensor components. normal work. In order to reduce the instantaneous impact load of the torpedo when it enters the water, in the existing reports and documents, the speed before entering the water is reduced by hanging a parachute on the torpedo, so as to reduce the potential damage to the torpedo head caused by the impact load of the water surface when the torpedo enters the water. , but this method has a slow water entry s...
