How To Make Composites Stick

According to Design News, composite materials can be challenging to use with adhesives or glues, as composites tend to attract the moisture that can foil a good bond with an adhesive. Combine that with the seemingly mutually exclusive need for composite and metal bonding, and it can seem like composites and adhesives weren't meant for each other. However, developments in adhesive technology have brought some products that work well at overcoming the challenges of gluing composites.

Instructions

1. • 1

     Prepare the surfaces to be glued by sanding, which creates abrasions for the glue to "grab." onto within the composite materials.

   • 2

     Apply glue to one surface of the composite material.

   • 3

     Join two pieces together. Clamp them together for drying. Let them cure for at least 24 hours.
