Carbon Fiber Composite Materials

While offering high strength, carbon fiber materials are highly brittle; direct tapping often leads to cracking, insufficient thread strength, and a high risk of galvanic corrosion between the fiber and metal. Bonded screws/nuts utilize structural adhesives to firmly integrate metal inserts with the carbon fiber. This method avoids substrate damage while providing high-strength threaded connections through the inserts. Simultaneously, the adhesive layer acts as an insulation barrier to block galvanic corrosion pathways. It is a reliable connection solution for carbon fiber structures, meeting the triple requirements of lightweighting, high strength, and corrosion protection.
