Abstract Amino terminated and π-conjugate naphthalenediimide (NDI) was designed and novel interphase with self-assembled NDI/multi-wall carbon nanotube (MWNT) was constructed on high-modulus carbon fiber (HMCF) surface, and the interfacial properties and reinforcing mechanisms of HMCF composites with various interphase were investigated. The nanoscale stiffening interphase with intertwined MWNT and flat ensiform nanostructure from NDI self-assembly were observed on MWNT@HMCF and NDI@HMCF surface...

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 ...

Abstract According to surface chemistry and topography of different high-modulus carbon fiber (HMCF), interfacial properties of various HMCF composite were evaluated, and nanoscale wetting analysis of HMCF were studied using experimental methods and molecular dynamics simulation. Hierarchical amount of active functional groups and nanoscale grooves were detected on the surface of pristine HMCF (p-HMCF), anodic oxidized HMCF (a-HMCF) and sized HMCF (s-HMCF). Remarkable enhancements in interfacial...

Abstract Tailored-modulus epoxy matrix was designed on basis of surface analysis of high-modulus carbon fibers (HMCF), and the effects of modulus intermediate layer on interfacial and mechanical properties of HMCF composites were investigated. Narrow grooves and active functional groups were detected on HMCF surface. The modulus of epoxy was tuned by stiff organic molecular structure of cycloaliphatic epoxy (CE) and amide acid (AA). Modulus intermediate layer was established along with modulus g...
