Functionally graded high temperature bonding of fiberglass fibers to steel

摘要

Method for chemical bonding of fiberglass fibers to steel surfaces to prepare the steel for bonding with carbon composite material. This fiber-bonding step greatly increases the strength of the subsequent metal-composite bond. The fiberglass fibers which are chemically bonded to the steel provide a high surface area interface to entangle with carbon fibers in the composite component, and thereby inhibit crack formation on the boundary surface between the steel and composite components when they are bonded together.
