AI Technical Summary

Technical Problem

Traditional bicycle frames are mainly made of metal, which is heavy and prone to rust, making it difficult to meet consumers' demands for lightweight and durable bicycles.

Method used

A lightweight bicycle frame material is prepared by using a composite material of nylon, alicyclic epoxy resin and hyperbranched polyamine modified carbon fiber through melt extrusion and injection molding processes. Nylon serves as the main continuous phase, alicyclic epoxy resin serves as a reactive toughening agent and rigidity reinforcing agent, and hyperbranched polyamine modified carbon fiber provides high strength and high stiffness.

Benefits of technology

It significantly improves the mechanical properties of bicycle frames, achieving lightweight and durable frames, solving the problems of heavy weight and easy corrosion of metal frames, and meeting the needs of consumers.
