Carbon carbon composite material has excellent properties such as high strength, light weight, fatigue resistance and so on. It is widely used in sports equipment, aerospace and other fields. Carbon fiber has excellent properties such as high strength, light weight, fatigue resistance and so on. It is widely used in sports equipment, aerospace and other fields.
carbon fiber filament diameter of T800 is smaller than T300 and T700, the difference between the fiber surface properties is large. T800 surface crystalline structure is more complete, resulting in high surface inertia, The existing conventional resin matrix is not suitable for the forming process of T800 carbon fiber.
The resin matrix has a great influence on the interfacial properties of T800 carbon fiber composites, T800 carbon fiber surface of the adhesive agent containing more ester groups, and TDE- 85 has a good compatibility with epoxy resin epoxy resin, TDE- 85 resin cured with T800 carbon fiber has a good interface properties, after adding proper amount of AG- 80 epoxy resin, the resin system has synergistic effect, so that the shear strength of the T800 carbon fiber composite material is further improved, reach 138MPa.
As the first choice of advanced composite materials, carbon carbon composites have been widely used in aerospace and other fields, and the demand is growing. The application of carbon carbon composites has become one of the important symbols to measure a country's level of development in the field of aerospace.
With the continuous progress of science and technology, carbon fiber production will continue to increase, gradually improve the quality, production costs decline steadily, a variety of excellent performance of CFRP will be more and more in the field of aerospace. Space remote sensing instrument is one of the advanced nature of the structure of the advanced nature, CFRP is an important material foundation for the realization of the structure of the advanced nature.
