Using bigHeads with composite materials

bigHeads can be embedded into composite materials during the moulding process, or surface bonded with adhesive afterwards. Each method offers different benefits.

Embedded in composite

  • Precise location from the mould tool
  • No secondary operations
  • High loads, even with thin material sections

Surface bonded

  • No holes in the composite
  • Single sided access
  • No witness on the “A” surface
