摘要: Abstract Automated Fiber Placement is being extensively used in the production of major composite components for aircraft industry. This technology enables tow-steered panels, which have been proven to greatly improve structural efficiency composites by means in-plane stiffness variation and load redistribution. However, traditional straight-fiber architectures are still preferred. One reasons behind this related uncertainties, as a result process-induced defects, mechanical performance laminates. experimental work investigates effect fiber angle discontinuities between different tow courses ply on un-notched open-hole tensile strength laminate. The influence several manufacturing parameters studied detail. results reveal that ‘ply staggering’ ‘0% gap coverage’ an effective combination reducing defects these
