Bicycle completely prepared from basalt-fiber-reinforced resin-based composite and preparation method thereof

Abstract

The invention discloses a bicycle completely prepared from a basalt-fiber-reinforced resin-based composite. Such components of the bicycle as a handlebar, a front fork, a vehicle frame, wheel hubs, a crank and pedals are prepared from the basalt-fiber-reinforced resin-based composite. The basalt-fiber-reinforced resin-based composite is mainly prepared from the following raw materials by weight: 70 to 75 parts of basalt fiber, 25 to 30 parts of resin, 0.5 to 15 parts of a curing agent, 0.25 to 3 parts of a mold lubricant and 0.125 to 3 parts of a promoter. According to the invention, the basalt fiber used in the invention is much lower in price compared with carbon fiber, so the cost for the bicycle is reduced; basalt fiber materials of different forms and resin are used for different components of the bicycle, so the mechanical properties of each component of the bicycle is maximally improved; a preparation method provided by the invention enables the content of the fiber to be increased to 60 to 70%, so product performance is greatly improved and product weight is low; and the preparation method is rapid in molding and saves cost.

Description

technical field [0001] The invention relates to a bicycle and a preparation method thereof, in particular to a full basalt fiber reinforced resin matrix composite material bicycle and a preparation method thereof. Background technique [0002] At present, based on urban traffic congestion and the smog climate caused by urban motor vehicle exhaust emissions, it has brought a series of impacts on people's life, life, production, etc., and is also based on people's desire for health, environmental protection, and low-carbon travel. And there is a strong need for an efficient, convenient and fast way of travel, especially in the state of short-distance travel in cities, people are in urgent need of a green and environmentally friendly way of travel. Under such circumstances, bicycles, a traditional way of travel, are favored by people as modern public transport. Traditional bicycles are generally made of steel pipes, aluminum alloy pipes, etc. through welding, riveting and othe...

AI Technical Summary

Problems solved by technology

However, the price of carbon fiber bicycles is very high, and its impact resistance is poor, so it is difficult to promote them in large quantities as public bicycles

In addition, the preparation process of carbon fiber bicycles is complex, the assembly line is long, and the number of workers required is large, which is also a main reason for its high price; at the same time, carbon fiber consumes a lot of energy, emits a lot of emissions, and is not environmentally friendly during the production process, which does not meet the requirements of green industries. development requirements

Patent CN102049830B introduces a method for manufacturing bicycle frames with composite materials, which uses fiber reinforced thermoplastic composite materials. Low, the rigidity of the bicycle frame is insufficient, and it still feels twisted and shaken during riding, which causes an uncomfortable feeling of riding
