[0034] With reference to Figure 4 The inner tube layer 14 is made of fluororubber as base rubber and mixed with nano ceramic particles and graphene powder at a mixing ratio of 5:3:2. The fluororubber as base rubber has excellent chemical corrosion resistance, high temperature resistance and oil resistance, which can effectively resist the erosion of brake fluid. The nano ceramic particles are uniformly dispersed in the fluororubber, which can significantly enhance the hardness and wear resistance of the rubber, so that the inner tube layer 14 can still maintain structural integrity under long-term erosion and friction of high-pressure brake fluid. The graphene powder is uniformly distributed in the fluororubber, which can greatly improve the tensile strength and gas barrier performance of the rubber, so that the inner tube layer 14 will not be broken or leaked when subjected to pressure impact during high-pressure braking, thereby ensuring the safe and reliable operation of the brake system.

[0035] With reference to Figure 4 The reinforcing layer 13 is woven with high-strength aramid fibers and uniformly distributed along the circumferential direction of the inner tube layer 14. The aramid fibers have ultra-high strength and modulus, and their woven structure enables the aramid fibers to be uniformly distributed in the circumferential direction of the hose, thereby enhancing the overall strength of the hose in all directions.
