Geometrical model of 3D layer-to-layer angle-interlock woven preforms with oblique structure

Abstract The original configuration of 3D layer-to-layer angle-interlock (LLA) woven fibers cannot be maintained during matrix impregnation and is unstable when the composite subjected to loading. in yarn are susceptible lateral sliding, resulting deformation textile geometry. initial modulus warp direction smaller can inconsistent owing geometry fabric. A stable (SLLA) fabric was devised by constructing a denser arrangement, properties this new structure were investigated study. geometric parameters novel reinforcing mathematically modeled, results validated experimentally. showed that SLLA more than LLA experimentally determined structural good agreement with theoretically calculated values.
