Popis: | This paper presents the automated fiber placement (AFP) manufacturing and high velocity impact response of hybrid pseudo-woven IM7/8552 carbon/epoxy composite laminates. Three 24 ply laminate configurations are studied where pseudo-woven sub-laminates are combined with traditional layups on the inside and outside, along with a third quasi-isotropic control laminate [45/90/-45/0]3s. Pseudo-woven sub-laminates are manufactured using a specialized in situ AFP process implementing tow skips. The pseudo-woven architecture is macroscopically heterogeneous with spatially varying fiber orientations both in-plane and through thickness resulting in multiple interfaces and an expanded design space. The impact experiments are performed according to ASTM D8101 in the range of 250–400 ft/s (76.2–121.92 m/s) using a single stage gas gun while utilizing digital image correlation and high-speed video to assess the laminate's response. Experimental results show that the hybridized configurations have a 45% reduction in back face surface damage, 19.5% less back face deflection and an increase of 5.5% in V50 velocity when compared to traditional laminate. |
