摘要

Composite laminates made with woven fabric are known to have better damage resistance characteristics than unidirectional laminates. Due to the recent development in fibre placement and tape laying machines, laminates with unidirectional plies are favoured because of the automated production process, AP-PLY combines the advantages of fabrics and unidirectional layers in an automated production process. AP-PLY is a laminate configuration obtained by placing the fibre tows in special patterns that mimic the construction of a woven layer. Any material system can be used for the construction, including glass fibre, carbon fibre, thermoset and thermoplastic resins and even dry fibre placement. No adaptations to current fibre placement machines are necessary. Tests show smaller delaminations and higher residual strength for every tested AP-PLY configuration and lay-up compared to baseline laminates with unidirectional plies. An energy dissipation redistribution is observed between fibre breakage and delaminations. Both thermoset and thermoplastic materials were tested. Possible applications include any number of the plies of wing and fuselage laminates or sandwich panel facesheets. It is also possible that entire laminate structures where the design is driven by damage tolerance can be constructed by AP-PLY. In addition, the prospect of eliminating or minimizing the use of fabric plies, which is a labour intensive process and replacing them with equivalent AP-PLY configurations, makes the present concept attractive for other applications where impact damage may not be the driver.
