J Appl Polym Sci 91: 2223–2233, 2004, We describe a study of the hot compaction of woven nylon 6,6 multifilaments produced by a patented procedure, developed at the University of Leeds, for creating novel single-polymer composites. f/5FJTqV2MtrbbWdzHtDmnxBEgpKZJKUkpSSlJKUkpSSlJKUkpSSmlndZ6Z02xtWde2l727mghxk +k7/AIeaWilw7O2ua62gn2ljmgj887gWku02R3+5LRTFp6mJ3X4x5IGx3fdpPqfDslopcv6kHiLM The FAUCa solution had a higher viscosity than the one prepared using the neat FA solvent, which can be an advantage in the applications which need higher viscosity like preparing the all-polyamide composite-coated fabric. PA6 film was plied on the single fiber and, a cover glass was placed on the film. When it processed in temperatures above 260°C, the CF/PA commingled composite reduces in 0.14J/°C the energy absorption ability due to the matrix degradation in high temperatures, leading to a considerable reduction on crashworthiness and its performance. paKWxP264u+2toa2KNnpl26YAyd4LnDnVkH4pGlImu+sn2KXV44zPTOgJNfqemCNd4Mep/d/KK9N proof:pdf The results showed that the proposed solvent (FAUCa) could readily dissolve PAs and less degradation during dissolution happens.
