Russian Carbon Fiber Research Deepened Day By Day

According to Russian media reports, Russian carbon fiber composite for aerospace industry Material Science There are many varieties, such as carbon plastic, carbon fiber woven fabric, carbon fiber knitted fabric and so on. During the manufacturing process of the parts, composite materials will have internal separation phenomenon, which is related to the heterogeneity and anisotropy of carbon fiber composites. In recent years, the quality of carbon fibers and fabrics produced by different enterprises in different processes has been uneven. If they are used in composite materials for rocket and radio aerospace technology, the use of units must be optimized for their manufacturers and production batches so that quality and performance can be guaranteed.

In view of this, Ural, Russia Chemistry Institute of science and other scientific research institutes on viscose based carbon fiber and viscose based carbon Fiber fabric A total of 6 kinds of microstructural analysis were carried out in order to accurately understand the data of carbon fiber structure and adsorption properties, which helps to analyze the quality of carbon fiber composite materials, and also correctly implement the correction procedures in parts manufacturing process, so as to minimize the defects and defects of the precision parts of Aerospace industry. The thermal mass analysis, mercury porosity and electron microscopy were used to study the sample length 2~3mm.

Experiments show that there may be some unpredictable "complexity" in the process of subsequent thermal processing of carbon fiber pores. The adsorption desorption process occurs when the carbon fiber composite or carbon fiber prepreg is processed at high temperature, resulting in poor quality of finished products. After heating and pressurizing, the adsorbed material is separated from the material and accumulated on the surface area of the fiber to form organic particles, thus increasing the probability of stress concentration and forming defects or defects in the carbon fiber composite.
