Carbon fibers used in carbon-carbon composites are usually continuously woven. During the preparation of composite materials, the structure of carbon fiber fabrics affects the density of carbon-carbon composites. Due to the uneven distribution of the matrix around the cross beam in the plain weave, the 8h satin weave is superior to the plain weave. For two-dimensional carbon-carbon composites containing plain weave reinforcement, the failure mode of the fiber bundle depends on the degree of bending of the fiber bundle. Fiber bundles with low bending degree fail under the combined action of tensile stress and bending stress. Circular fibers are more popular than irregularly shaped fibers because the latter causes stress concentration points in the matrix near the fiber corners. The generation of microcracks occurs at these points, resulting in low-strength carbon-carbon composite materials.

Carbon fiber for carbon-carbon composites is usually continuously woven. In the process of composite material preparation, the tissue form of carbon fiber fabric affects the degree of density of carbon-carbon composite materials. 8h satin tissue is superior to flat tissue due to the uneven distribution of the base around the cross-beam in the flat tissue. For two-dimensional carbon compositematerials containing flat-reinforced materials, the pattern of fiber bundle damage depends on how bent the fiber bundle is. Fiber bundles with small bending are defeated by the combination of stretch stress and bending stress. Round fibers are more popular than irregularly shaped fibers, which cause stress concentration sprang to the substrate near the fiber angle. Microcracks occur at these points, resulting in low-intensity carbon composites.

In the process of composite preparation, the microstructure of carbon fiber fabric affects the densification of carbon carbon composite.
