title = "Research on influence of preform manufacture parameters on properties of carbon/carbon composites",
abstract = "Needle-punched carbon fiber performs possessing high designable characteristic, good global property and high anti-shear strength have been used widely as reinforcement framework of high temperature composites for aerospace application. Influences of the needle-punched density and its depth as well as the plane density of fiber felt on the fibre bulk fraction of perform and the properties of carbon/carbon composites are investigated. The relation between mechanical properties of the composites and the density of preform is analyzed forecasting. It has been shown that by the test, With the increasing of the needle-punched density from 20p/cm2 to 50p/cm2, the tensile strength increases first and then decreases, but the interlaminer shear strength increases; The tensile strength and the interlaminer shear strength all increase with the increasing of needle-punched depth from 10mm to 16mm, while decrease with the increasing of plane density of fiber felt before 300g/m 2. Simulating by origin software when only one of the needle-punched density, its depth and plane density of fibre felt changes, the preform density influences the tensile strength and interlaminer shear strength remarkably. So preforms density can forecast the properties of carbon/carbon composites as macro-parameter.",
