The bicycle frame material is prepared from the following materials in parts by weight: 12-26 parts of nano aluminium carbide, 12-28 parts of carbon fiber, 8-25 parts of nano silica, 9-18 parts of polycarbonate, 7-16 parts of polyamide, 8-20 parts of boron fiber, 18-40 parts of carbon steel fiber, 6-19 parts of polystyrene, 6-14 parts of hexamethylene diisocyanate and 7-14 parts of polyetheretherketone fiber. Compared with the prior art, the bicycle frame material provided by the invention has the advantages that (1), the bicycle frame material is light, high in toughness and long in service life; (2), the bicycle frame material is low in production cost and inexpensive.

Description

technical field [0001] The invention relates to a method for manufacturing a bicycle frame, in particular to a light and tough bicycle frame material and a preparation method thereof. Background technique [0002] Bicycle is a common means of transportation, how to produce a safe, light, environmentally friendly, and affordable bicycle frame has always been an important issue that determines the development of this industry. The materials used to manufacture bicycle frames mainly include the following types: aluminum alloy, titanium aluminum alloy, and carbon fiber. Among them, due to the problems of low elastic modulus and rigidity, aluminum alloy must undergo heat treatment, otherwise the strength is not enough, and factories of general scale cannot afford heat treatment equipment. Titanium-aluminum alloys also have certain shortcomings as bicycle frame materials. The price of titanium alloys is too high, and it exists in the form of titanium dioxide in nature. The extrac...
