The combination of different carbon-based fillers (commercial plate graphite (GR) and rod carbon fiber (CF)) were added as conductive fillers to improve the thermal conductivity of polypropylene (PP). The effect of different ratio of carbon-based fillers on the thermal and mechanical properties of GR/CF/PP composites was investigated in detail. A remarkable synergistic effect between GR and CF in improving thermal conductivity of PP composites has been achieved. The results show that the in-plane thermal conductivity rises to 2.8 W·(m·k)-1 at a GR/CF ratio of 5:1 (the total mass fraction of carbon-based fillers to 40wt%), which is 14 times as the thermal conductivity of pure PP (0.2 W·(m·k)-1) and also much higher than that of single filler composites.

Thermal And Mechanical Properties

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.

Fiber Sample

The electrical, mechanical and thermal conductivity of ethylene butene copolymer (EBC) composites with carbon fibers were studied. EBC/carbon-fiber composites can be utilized as an electro-mechanical material which is capable of changing it electric resistance with mechanical strain. Carbon fibers were introduced to EBC with different concentrations (5-25 wt%). The results showed that the addition of carbon fibers to EBC could increase the electric resistance up to 10 times. Increasing the load to 2.9 MPa could increase the electric resistance change by 4500% compared 25% fiber sample with pure EBC. It is also noted that the electric resistance of the EBC/CF composites underwent a dramatic increase with raising the strain, for example, the resistance change was around 13 times more at 15% strain in comparison to 5% of strain; The thermal conductivity tests showed that the addition of carbon fibers could increase the thermal conductivity by 40%, from 0.19 to 0.27 (Wm-1K-1). It was also observed that the addition of carbon fibers to EBC could increase the thermal conductivity.
