摘要：

Mechanical drilling of carbon fibre-reinforced polymer (CFRP) composites is common in industrial appli-cations, but suffers from extensive tool wear, fibre delamination and high tooling cost. This research shows that by using simultaneous laser and mechanical hybrid drilling, tool life can be increased by 88% and a 36% reduction in unit process Scope 2 carbon emissions can be realised without increasing drilling time. This was achieved in laser-mechanical hybrid drilling 6.5 mm diameter holes in CFRP sheets of 6 mm in thickness. The holes drilled with the hybrid drilling method have no fibre delamination even without using a support material. The material characteristics and drilling mechanisms are discussed. The results are compared with traditional dry mechanical drilling process. Cradle-to-gate life cycle analysis is carried out to estimate the carbon emission.& COPY; 2023
