The fabrication of carbon-fiber composites by aqueous suspension prepregging with larc-tpi and peek
A novel method of impregnation was used to make thermoplastic prepregs with aqueous suspension of polymer powder and AS-4 carbon fibers. The prepregging, consolidation, and laminate evaluation procedures are described in this report. The need and importance of a dispersing and binding agent and its …

An early-emerging explanatory heuristic underlies the tendency to defend the status quo
People often view their sociopolitical systems as fair and natural despite glaring biases in their structure. Current theories of this striking phenomenon trace its roots to a motivation to alleviate anxiety and uncertainty. Here, we propose an alternative origin for these system-endorsing …
