AI Technical Summary

Technical Problem

Existing pultrusion processes have high power consumption and low manufacturing efficiency. Ground-based production processes are not suitable for on-orbit manufacturing. The strip feeding method has high resistance, wastes thermal energy resources, and has low cutting efficiency. In addition, traditional robotic arms have complex structures and cannot meet the manufacturing requirements of on-orbit robotic arms.

Method used

The strip coil forming method is adopted, which strengthens the strip conveying by pushing before forming and pulling after forming. The hot melt welding technology is used, combined with the cooling component to recover heat energy, and the cutting process is optimized by the ring cutting component. Carbon fiber reinforced braided layer and polyetheretherketone resin matrix material are used.

Benefits of technology

It improves the efficiency and energy utilization of on-orbit manufacturing, reduces strip conveying resistance and heat waste, and enables rapid manufacturing and efficient cutting. The device is small in size and compact in structure, and can adapt to the length requirements of different parts.
