Abstract Synergetic strengthening effects of epoxy grafted polyurethane (EP-PU) and aminated MWCNTs (MWCNTs-NH2) on mechanical performance of EP-based composites at 77 K were systematically investigated using the tested results at room temperature (RT) as comparisons. EP-PU was successfully synthesized by controlling the reaction between –OH in EP and –NCO in PU prepolymer, which showed the advantages of relatively low viscosity and outstanding chemical miscibility with EP matrix. The most obvio...

Abstract A novel phthalocyanine-based interphase with a higher crosslinking density and glass transition temperature (Tg) was designed to enhance the interfacial properties of the carbon fiber/epoxy composite at elevated temperatures. The crosslinking density and the Tg of the interphase were tailored by tetraaminophthalocyanine (TAPc) with abundant amine groups and rigid heteroaromatic structures coated on the surface of the carbon fibers. Characterizations of the fiber surface properties were ...

As the key strategic materials for national security, carbon fibers (CF) and CF reinforced composites must be independently guaranteed. Among them, the amount of carbon fiber reinforced polymer (CFRP) composite material accounts for more than 70% of carbon fiber composites. Resin matrix (content over 35 wt%) is one of the two basic materials of CF reinforced polymer composites, which directly determine the service performance and processing of the composites. The Advanced Composites Center (ACC)...
