FusePly® 350

FusePly® 350

FusePly® 350 is a technology designed to achieve reliable bonding through creating covalent chemical bonding interface in adhesive joints of pre-cured composite structures using either conventional co-bonding or secondary bonding processes. 

FusePly® 350 is compatible with most commercial 350°F cure epoxy-based prepregs and adhesive systems and requires no additional processing steps, such as sanding or solvent wiping prior to bonding. 

Through patented technology, FusePly® is able to bring a new level of reliability to the bonding process by creating a chemically-active surface for bonding, rather than just a mechanically-prepared surface as with traditional peel plies, sanding, or plasma surface treatment. 

FusePly® delivers structural performance and dependability of co-cured bonded structures with the convenience and flexibility from using pre-cured composites. FusePly® was designed to be processed and handled just like conventional peel ply surface treatments, allowing for seamless insertion of the technology into a manufacturing shop. The system, supplied in film form with a polyester peel ply fabric, is engineered to offer a clean, fiber-free surface for composite bonding applications. 

Features and Benefits

• Chemically-bonded interface creates unitized structures
• Handling and processing is similar to conventional peel ply films
• Compatible with most 350°F (177°C) epoxy-based commercial prepregs and adhesives
• Minimizes the number of processing steps and reduces assembly time
• Contamination-free surface, with no residual fibers, provides ideal surface for bonding
• Superior reliability and bond performance for composite structures versus conventional surface trea®ent options
• Outperforms traditional surface preparation methods including plasma surface trea®ent
• Provides 100% cohesive failure
• Easy removal of peel ply fabric following cure
• Suitable for co-bonding and secondary bonding of composite parts
