Abstract

The invention discloses a basalt fiber reinforced flame-retardant PBT composite material and an application thereof, and relates to the field of materials. The material is prepared from raw materialscomposed of modified basalt fiber, flame-retardant PBT (polybutylene terephthalate) resin masterbatches, a coupling agent, a flexibilizer and high-mesh-number talc powder, and is mainly used for preparation of bicycles. The composite material provided by the invention has simple preparation method and excellent comprehensive performances; and bicycle parts prepared from the composite material, such as bicycle handlebars, front forks, frames, wheel hubs, cranks, pedals, brackets, safety forks and mud fenders, have the advantages of light weight, high strength, good dimensional stability and excellent flame retardancy, fatigue durability, chemical resistance, creep resistance and impact resistance. In addition, the composite material can also be combined with different metal structural inserts to prepare high-strength bicycles with complex structure; meanwhile, the production period is short; the production cost is low; and a product is recyclable.

Description

technical field [0001] The invention relates to the technical field of materials that can be used in the manufacture of bicycle parts, in particular to a basalt fiber reinforced flame-retardant PBT composite material. Background technique [0002] In recent years, bicycles have become an efficient, convenient and fast way of travel as an environmentally friendly means of transportation in cities. Based on the desire for health and environmental protection, more and more people use bicycles (road bikes, mountain bikes) as fitness equipment for cycling or to participate in competitive sports, and as a modern lifestyle To praise. In this environment, bicycles, a traditional means of transportation, are gradually being favored by people as a means of modern transportation. Traditional bicycles are generally made of metal materials such as steel pipes or aluminum alloy pipes, and are manufactured by welding, riveting and other technologies. Not only are the stamping and welding...
