Laser ablation

Overview

The ablation process works by removing the matrix (ie resin) from the composite. It does this by vapourising the resin with a low energy density using a TEA CO2 laser. There is no contact during the process avoiding the traditional machining and grinding where fibres may suffer local damage. The exposed fibres are brushed away until the repair is ready for replacement material to be bonded in place.

Advantages

  • Semi-automation of the preparation process for repairs to composite parts
  • In field capability
  • Reduces time and cost
  • Efficient repair

Used on

  • Ability to be used on all composite structures
