Effect of current intensity on properties of the carbon fiber fabric and composites

Abstract The carbon fiber fabric was electrified at the current intensities of 4 A for 1 h, 8 for1 16 h and 2 then reinforced epoxy composite laminates (CF/EP) were prepared. effects different on surface temperature fabric, micro morphology fiber, mechanical properties CF/EP composites fracture tensile specimens studied. significance effect investigated by means quantitative statistical analysis. results show that maximum during heating is 115 °C ~125 °C; At level α= 0.01, not significantly affected intensities; treated with intensity from untreated. After grooves deepened granular protrusions increased; No obvious difference observed in samples intensity. self process composites, when single-layer less than it will have no significant impact composites.
