| Abstract: | High-performance carbon fiber has been widely used in commercial and military fields because of its highstrength , light weight and high stiffness. However , the application of higher performance carbon fiber ( e. g. T800)would cause worse mechanical performances because of the ext reme inertness of it s surface caused by the alignmentof graphitic crystallites. In order to produce the high-performance resin mat rix , which can bond T800 carbon fiber(CF) well , the sizing of T800 CF was analyzed. The effect of resin mat rix’ s st ructure and property on T800 CFcomposite was studied based on the analysis. Meanwhile , the mechanical property and thermal mechanical propertyof the resin and it s carbon fiber composite were analyzed. The result s show that T800 sizing possesses high contentof ester , which can possess excellent interfacial properties with glyceride epoxy. With the help of the optimized resinsystem , the T800 CF composite possesses excellent interfacial properties and heat-resistance properties. The interlaminar shear st rength ( ILSS) of the composite is 138 MPa , the tensile st rength of NOL rings is 2530 MPa , and theglass t ransition temperature ( Tg ) is 213 ℃. |
