FusePly® for composite bonding
FusePly® is a breakthrough composite bonding technology that enables the build of reliable bonded composite structures using conventional manufacturing processes. FusePly® products eliminate the need for other more costly surface preparation methods and provide an enhanced surface for bonding by creating a chemically bonded interface. FusePly® addresses manufacturing challenges faced by aircraft builders such as improved performance, build rates and lightweighting.
FusePly® offers step-change bonding performance and benefits to users
- Lower assembly time
- Improved reliability
- Higher part performance
- Lightweighting
- Design freedom
FusePly® Properties:
- Processing and Surface Features: The tack and handling characteristics of FusePly® products have been optimized to allow for easy lay-up and processing.
- Bonding Results: This new technology is compatible with most amine-cured epoxy prepregs and is universal in nature.
- Interfacial Durability: The chemically bonded interface created by this new technology is more durable than the interface created by conventional bonding processes, which create mechanical bonds.
- Pre-Bond Stability: The chemically active surface is not affected by moisture or out-time.

“Too often today the industry practice is to bond composite structures with an adhesive and then drill holes in the joints and add mechanical fasteners, because the designers have no way of guaranteeing that the bond is good. However, drilling holes actually weakens the composite structure, and the fasteners add weight. As we advance the reliability of adhesive bonding through our new FusePly® technology, we can help the industry move away from fasteners, and toward lighter and stronger structures, which finally takes full advantage of building with composites instead of metal.”
