Composite material with layering structure design and application thereof

The invention relates to the field of technical aerospace materials, in particular to a composite material with a layering structure design and application thereof. The composite material structurally comprises a main force bearing area, a U-shaped anti-cracking area and a concentric-square-shaped anti-cracking area, the U-shaped anti-cracking area serves as a secondary outer layer of the composite material, is of a U-shaped structure and wraps the main force bearing area in the middle of the composite material, the concentric-square-shaped anti-cracking area serves as an outer layer of the composite material and wraps the U-shaped anti-cracking area in a concentric-square-shaped structure, and the main force bearing area, the U-shaped anti-cracking area and the concentric-square-shaped anti-cracking area are all prepared from fiber reinforced materials. Compared with a traditional design structure that all the layers are 0 degree, the composite material with the layering structure design has the advantages t
