Example Embodiment
[0033] Example 1:
[0034] A carbon fiber reinforced wear-resistant high-temperature nylon composite material. Its components and contents are shown in Table 1 below. Among them, the Mohs hardness of the soft filler is less than or equal to 2, the Mohs hardness of the hard filler is greater than or equal to 5. The PAN-based milled carbon fiber after oxidation treatment, the monofilament diameter of PAN-based milled carbon fiber before the nitric acid liquid-phase oxidation method is 7μm, and the average fiber length is 100μm.
[0035] The preparation method of the carbon fiber reinforced wear-resistant high-temperature nylon composite material in this implementation is as follows:
[0036] (1) Put the soft filler and the hard filler in an electric blast drying oven, dry at 100°C for 8 hours and then mix evenly to obtain a mixed filler. Dissolve the coupling agent in isopropanol to prepare a coupling agent solution , And keep the quality of isopropanol 20 times the mass of the coupli...
