摘要: In consequence of an increased interest in using endless carbon fibre reinforced thermoplastic composites (TPC), automated and highly productive processing technologies for cutting trimming steps consolidated materials are sought. this paper, the influence on thermal effect caused by laser with respect to static strength properties TPC based a polyphenylene sulfide (PPS) matrix is studied. For experiments, laminates at varying thicknesses up s = 3.1 mm disc emitting wavelength ! 1030 nm maximum output power PL 2 kW used. first time, resulting magnitude heat affected zone (HAZ) edge composite material correlated interlaminar shear tests. The results compared specimens prepared milling abrasive water jet cutting. Depending laminate thickness, treated samples show compara- ble those conventionally processed specimens. A reduced load bearing area, as damaged fibre-matrix-adhesion due impact, identified main factor reduction strengths higher thicknesses.
