Induction Bonding for Structural Composite Tubes.

摘要

Large structural composite tubes, prototype components for a proposed U.S. Navy application, are bonded by induction curing of an engineering adhesive. Magnetic powder is used as the susceptor material and is directly incorporated into the adhesive prior to processing. Different induction power supplies, coil designs, and adhesive formulations are investigated. Final demonstration runs bond 9-in-long, 3-in-diameter axisymmetric bondlines in 15 min. These results demonstrate for the first time the successful induction bonding of large structural composite components using magnetic particulate susceptors.
