摘要: Abstract This paper investigates the manufacture of selectively reinforced metal/composite hybrids in a laser-assisted automated tape placement process. Carbon-fibre/PA6 composite tapes were applied to PA6-coated steel substrates. The bonding first-ply substrate is critical success hybrid; effect rate was investigated for speeds 25 mm/s, 50 mm/s, 100 mm/s. interfacial bond strength hybrid laminates determined by ASTM D 3165 lap shear tests. A 3D finite element thermal model formulated elucidate behaviour increasing rate. method efficiency shown significantly decrease computational difficulty while maintaining solution accuracy. Raising from 25 mm/s 100 mm/s resulted fourfold increase with maximum value 22 MPa. greater at higher attributed improved synchronisation temperature and consolidation pressure history.
