The density of carbon fiber is only 1.7g/cm³. Accessories of the same specification are more than half lighter than those made of aluminum alloy, but their strength is much greater. In addition, carbon fiber also has strong corrosion resistance. A considerable proportion of wheelchair patients face Problems such as incontinence and frequent contact with injections and liquids. In this case, carbon fiber composite accessories show durability that is difficult to match with ordinary metal materials. Compared with ordinary wheelchairs, wheelchairs made of carbon fiber are lighter and more rigid, which can effectively improve the user's comfort. Moreover, the use of carbon fiber on the side walls of the wheelchair can avoid low-temperature damage caused by poor thermal conductivity of the material.

At present, carbon fiber composite materials(carbon fiber tubes/pipes) are mainly used in accessories such as handrails, arm rests, foot rests, leg rests, backrests, skirt guards, and frame tubes. Most of these accessories can adjust the height. Carbon fiber composite materials are easy to assemble with the wheelchair through mechanical connections. The most important thing is that after using carbon fiber composite materials for these accessories, the overall weight of the wheelchair has been significantly reduced, and as highly used parts, it has also become stronger and more durable.

Carbon fiber tubes are also widely used in wheelchairs because their standardized specifications greatly reduce costs and development cycles.
