Carbon fiber honeycomb tube structure

Abstract

The invention discloses a carbon fiber honeycomb tube structure, and relates to the field of protective structures. A traditional protective structure is high in weight and simplex in material and structure form. A carbon fiber honeycomb tube is prepared from pultrusion tubes with orthogonal carbon fibers being laid, and the large tubes and the small tubes are connected into a whole through resin.The carbon fiber tube structure obtained through a pultrusion process has the advantages of large strength, high stiffness, fast forming and the like, and is lower in weight, larger in stiffness andhigher in specific energy absorption compared with the traditional protective structure; and the needed forms can be prepared according to the demands, and the application range is wide.

Description

technical field [0001] The invention relates to the field of protective structures, in particular to a carbon fiber honeycomb pipe structure. Background technique [0002] In the field of protective structures, in the face of high-speed collision objects, the energy absorption characteristics of the protective structure play a crucial role in the effectiveness of its structure. Whether it can rely on various failure modes such as buckling, damage, and fracture of its own structure to reduce the impact load during high-speed collisions and dissipate impact energy is a matter of great concern in the field of protective structures and other fields. For example, the anti-missile penetration process of the target body; the soft landing process of the last stage buffer energy-absorbing device of the aerospace vehicle; the landing process of the landing gear device when the aircraft lands; the landing process of the airdrop system equipment for military equipment; the guardrail on ...

AI Technical Summary

Problems solved by technology

When the above-mentioned materials are used as energy-absorbing structures, their specific energy absorption and specific strength are relatively low, and it is difficult to achieve the energy-absorbing effect required by the design. Moreover, these materials have a single form, and the manufacturing steps are cumbersome, and the obtained protective structures are often relatively heavy.
