IMPACT TESTING OF CARBON FIBER-EPOXY RESIN COMPOSITE WITH GRAPHENE

Emulsion type sizing agent for carbon fiber was synthesized using epoxy resin (E-51) and epoxidized polybutadiene (EPB) by adding emulsifiers and other additives. Standing stabilization of sizing agents was analyzed. Meanwhile, abrasion resistance, fluffs and breakage, stiffness were used to analyze the processability of carbon fiber. The effect of sizing agents on interfacial adhesion of carbon fiber/resin composites was estimated by interlaminar shear strength (ILSS). The results showed that the sizing agent could significantly improve processability of carbon fiber due to the increase of abrasion resistance and reduce of fluffs and breakage. By adding EPB in sizing agent and adjusting the ratio to E-51, the flexibility of carbon fiber was ameliorated and the sizing agent could adapt to various resin matrices. Compared to the desized carbon fiber reinforced composite, ILSS of sized carbon fiber/epoxy resin composite was increased by 16.9%, and ILSS of sized carbon fiber/vinyl ester resin composite was enhanced by 19.1%.

Carbon fiber epoxy resin composite and polyimide material are likely to be applied to pulley-guideway system of the new satellite antenna. Their tribological properties have effects on the motion characteristics of the pulley-guideway system. To master the tribological properties of carbon fiber epoxy resin composite and polyimide material, this paper carries out tests of tribological properties and wear behavior of carbon fiber epoxy resin composite and polyimide material at 130°C and 30°C. Carbon fiber epoxy resin composite is used as the grinding specimen and polyimide material is used as the counter-grinding specimen. Tribological properties of this material pairs is studied under diverse linear velocity and external loads. The results show that friction coefficient of this material pairs is stable under different conditions, especially at 30°C. Meanwhile, wear behavior of this material pairs is mainly affected by ploughing of surface roughness at low temperature, while by surface micro-spalling at high temperature.
