Application of Aramid Fibers in Recycled Rubber Hoses for Automobiles

Aramid fiber is one of the commonly used skeleton materials in rubber products, and it is widely used in various rubber products due to its excellent performance. The use of recycled rubber in the production of automotive rubber hoses can effectively reduce costs. Automotive rubber hoses containing recycled rubber, such as fuel hoses, heater hoses, and power steering hoses, can use aramid fibers as reinforcement materials to further improve the comprehensive performance of automotive rubber hoses. So, what are the performances of aramid fibers? How are aramid fibers applied in recycled rubber hoses for automobiles?

Understanding aramid fibers definition

Aramid fibers are high-modulus aromatic polyamide fibers, which have properties such as high strength, high modulus, high temperature resistance, acid and alkali resistance, and light weight. They have the advantages of synthetic fibers and steel wires. Their modulus is 2 to 3 times that of steel wire or glass fiber, and their toughness is twice that of steel wire. Their weight is only 1/5 that of steel wire, so they are also called synthetic steel wires. Among them, Fanglun 1414 has a small density, high strength, good heat resistance, and also has good insulation and corrosion resistance, making it an ideal raw material for recycled rubber hoses for automobiles.

The skeleton material in the hose should have properties such as high temperature resistance, high pressure resistance, high strength, good fatigue resistance, and the shrinkage rate should not be too large, and it should be easy to bond with rubber. The vulcanization methods of the hose include steam direct vulcanization, salt bath vulcanization, thermal convection vulcanization, etc., and the vulcanization process and the properties of the hose determine that the skeleton material of the recycled rubber hose needs to have characteristics such as high temperature resistance, high pressure resistance, high strength, good fatigue resistance, and a small degree of rigidity to reduce the noise generated during the use of the hose.

Application of aramid fibers in recycled rubber hoses for automobiles

For power steering hoses, using aramid fibers as the reinforcement layer can improve the high pressure resistance, high temperature resistance, and durability of the hose. Using high-strength Fanglun 1414 can appropriately reduce the number of fiber reinforcement layers while ensuring the pressure resistance, thereby reducing the rigidity of the hose and reducing the noise generated during the use of the hose.

Recycled rubber fuel hoses are used for refueling pipes of fuel tanks on automobiles, and the use temperature is relatively low. Using aramid fiber HY8S1J2Y-MXF as the skeleton material can enhance the performance of the hose.

The hose used in the engine cooling circulation system is a soft connector that circulates cooling water between the engine jacket and the radiator. Adding aramid fibers to the hose can improve its pressure resistance, temperature resistance, and durability.

The aramid fiber applications in recycled rubber hoses for automobiles can improve the pressure resistance, heat resistance, and durability of the hoses, thereby improving the overall performance of the automobiles. In practical operations, aramid fibers need to be processed and processed, and their stickiness needs to be appropriately increased in the design formula.
