The thermal and mechanical properties of carbon fiber/flake graphite/cyanate ester composites

The paper studies new high-temperature thermoplastic impregnated unidirectional carbon fiber composites. The research focuses on the effect of thermal and chemical oxidation of the carbon fibers surface on the interfacial interaction between fibers and polysulfone and polyphenylene sulfide as well as thermal and mechanical properties of the composites. The research reveals the interaction between carbon fibers and the polymer matrix depend both on the type of surface treatment and nature of the polymer. The chemical oxidation of carbon fibers results in good interfacial interaction, and the best mechanical properties were observed for tows impregnated with polyphenylene sulfide.

An electro-activated type shape memory cyanate ester-epoxy (CE-EP) composites containing short carbon fiber (SCF) and carbon black (CB) were fabricated, where SCF linked among CB particles to make the superior conductivity network in compositions. In the compositions, the content of CB was fixed at 5 wt%, while the amount of SCF was ranged from 0 to 0.9 wt%. The synergistic effects of SCF and CB on the mechanical properties test, electrical properties, SEM, DMA and the electro-activated type shape memory experiment was reviewed. The outcomes showed that when the parts of SCF is less than 0.9%, the mechanical properties and storage modulus of required compositions expand with the content of the SCF growth. But, when the SCF content reaches 0.9 wt%, the flexural strength and storage modulus of the compositions decrease slightly. With the growth of SCF content, the glass transformation temperature increases from 89 °C to 103 °C and the resistivity of the composites decreases gradually. The resistivity of the composites is only 7.37 Ω/cm with 0.9 wt% of SCF. Further, the thermal response speed and shape convalescence rate of the compositions increase greatly with the growth of SCF content.
