Effect of VGCF Addition to Carbon Fabric/Ep
Despite of the excellent properties of carbon nanofiber, the properties of carbon nanofiber filled polymer composite were not improved as much as expected. The usual reason may be not sufficient dispersion of the nanofibers within the composites. For the improvement in the mechanical properties of composites, the carbon nanofiber reinforced hybrid composites was investigated. For the dispersion of the carbon nanofiber, the solution blending method using ultrasonic was used. The hybrid composite was manufactured by the Solution-Dip-Type prepreg manufacturing machine. This machine is consisted of resin bath, curing tower that evaporates solvent and process controller for manufacturing speed. The prepregs were cured in an Autoclave. 3 wt% of carbon nanofiber containing hybrid composite, Carbon Fabric/Ep, was tested by Universal Testing Machine. The tensile strength and modulus were improved by 25% and 35%, respectively. In-plane shear strength and modulus were improved by 45% and 78%, respectively.
