1. Bonding materials

In industries that use composite materials, there is a need to bond various materials and parts, not just composites, such as :

• sandwich panel skins, which can be :

  • aluminum or alloy sheet metal,

  • thermosetting laminates (polyester-glass or graphite-epoxy, or other phenolic-glass for high fire resistance),

  • thermoplastic composites, more rarely ;

• various honeycombs: aluminum, Nomex (based on aramid or Kevlar fibers) ;

• curved composite parts, stiffeners, pultruded profiles, made from thermosetting prepregs, which must then be bonded or laminated by co-curing (simultaneous curing of resin, composite and adhesive). These are composite-on-composite bonds;
