The wheelchair is a very great invention that has brought great help to people with limited mobility. The wheelchair has developed more practical functions from the original special means of transportation, and has moved towards the development direction of light weight, humanization and intelligence. How to lighten it? It is bound to be considered from the material of the wheelchair. Carbon fiber, as an important material for lightweight automobiles, is also suitable for wheelchairs.

Carbon fiber is a kind of high-end aerospace materials, and it is currently the strongest one among composite materials. In addition to being light, its high strength, friction resistance, fast heat conduction, corrosion resistance, good moisture resistance and waterproof performance are also its main features.

The advantages of carbon fiber wheelchairs over ordinary wheelchairs

1. Lightweight: For wheelchairs of the same size and specifications, the carbon fiber material can reduce the weight by 30% compared with the traditional metal material. Whether it is a manual wheelchair or an electric wheelchair, it can save the user’s worry and effort.

2. Long service life: Wheelchairs are usually composed of wheels, hand rims, seat seats, brakes, backrests, cushions, rubber supports, leg supports, arm supports and armrests. If one of these components fails, it may affect the wheelchair. Normal use. The wheelchair parts made of carbon fiber have good fatigue resistance, strong impact resistance, and small damage caused by collision; at the same time, the creep property is close to 0, and it is used for a long time and high frequency, so there is no need to worry about the aging, wear and deformation of the parts.

3. Corrosion resistance: Some wheelchair users may experience incontinence and drug spillage. All parts of the wheelchair need to be able to resist the erosion of pollutants and have a certain acid and alkali resistance.

4. Corrosion and oxidation resistance: Traditional metal wheelchairs will rust when used for a long time, but carbon fiber wheelchairs do not have this problem. In addition, wheelchairs may face light and oxidation for a long time, and metal materials are more prone to deformation and oxidation. Carbon fiber composite materials perform better in this regard.

5. Avoid secondary injuries: The purpose of patients using wheelchairs is to protect themselves and avoid secondary injuries. The carbon fiber wheelchair has a certain shock absorption effect, and the comfort and safety are better when going up and down the stairs and steps.

Carbon fiber wheelchairs have great performance advantages, but they also have certain disadvantages. The disadvantage is that they are expensive. High-end hospitals wear carbon fiber wheelchairs, which is why we rarely see them.
