Carbon fiber bar skeleton of composite material in four-dimensional carbon fiber bar

Abstract

The invention relates to a carbon fiber bar skeleton of a composite material in a four-dimensional carbon fiber bar. The carbon fiber bar skeleton is characterized in that: four groups of the carbon fiber bar skeletons are arranged and comprises a left group, a right group, a front group and a back group, each group of the carbon fiber skeletons is composed of a plurality of rows, the rows are parallel with each other, each row is composed of a plurality of round carbon fiber bars, the round carbon fiber bars are parallel with each other, all the carbon fiber bars between adjacent groups are mutually perpendicular to each other on a vertical projection surface, each group of the carbon fiber bars form same included angle with a horizontal plane, the four groups of the carbon fiber bars skeletons lie on a same horizontal plane, row spacing of the four groups of the carbon fiber bars skeletons are all equal to that of the carbon fiber bars in each row, four carbon fiber bars of the four groups of the carbon fiber bars skeletons on a same row is tangent at a point, and the tangent points among the four carbon fiber bars in the same row lie on a same horizontal plane. The advantages reside in that: a unit of the carbon fiber bar is in a rectangular pyramid shape, a structural body is difficult to be distorted and deformed; incised from whatever the direction is, the carbon fiber bars form a net shape, accordingly the carbon fiber bars bear uniform force and multidirectionally resist impact force. Open channels is existed between all the carbon fiber bar skeletons, so has big a space duty ratio, are extended to a CVD process, and make the treatment of the filling very smooth.

Description

technical field [0001] The invention relates to a carbon fiber rod structure composite material, in particular to a carbon fiber rod skeleton of a four-dimensional carbon fiber rod structure composite material. Background technique [0002] At present, three-dimensional carbon fiber rod composite materials have been widely used in various fields such as aerospace and high-end industries because of their excellent properties such as high temperature resistance, corrosion resistance, and impact resistance. However, in the actual application process, the three-dimensional carbon fiber rod composite material has the following defects because the carbon fiber used is a three-dimensional horizontal, vertical and longitudinal structure: [0003] One: Since the force is not enhanced from multiple angles, the force intensity is not uniform enough (the force intensity on the section is inconsistent), and it cannot resist the impact force in multiple directions; [0004] Second: Since...

AI Technical Summary

Problems solved by technology

[0003] One: Since the force is not enhanced from multiple angles, the force intensity is not uniform enough (the force intensity on the section is inconsistent), and it cannot resist the impact force in multiple directions;

[0004] Second: Since it is composed of chopped carbon fiber rods, the solid properties of carbon fiber rods are limited, and their advantages such as high temperature resistance, corrosion resistance, and impact resistance are not fully reflected;

[0005] Third: Because the duty ratio of the three-dimensional carbon fiber rod skeleton inside the three-dimensional carbon fiber rod composite material is relatively large, and the gap between them is small, when the three-dimensional carbon fiber rod skeleton is put into the mold for reinforcement, polymethyl methacrylate, epoxy resin , polyarylethylene silicone resin, reinforced polyether ether ketone, will produce resistance when casting, resulting in the casting of reinforced polymethyl methacrylate, epoxy resin, polyarylethylene silicone resin, reinforced polyether ether ketone, etc. Bubbles are generated, so the composite material produced has flaws. When composite materials are used in high-tech and high-end aerospace fields, when encountering high temperature and high pressure, small flaws will cause the collapse of the entire structure, resulting in Therefore, it is urgent to develop a new four-dimensional carbon fiber rod structure composite material with a new carbon fiber rod skeleton structure that can overcome the above shortcomings.
