Properties of multiaxial and 3-D orthogonal woven carbon/epoxy composites
- North Carolina State Univ., Raleigh, NC (United States)
A new three-dimensional multiaxial weaving technique was developed at NCSU. Rectangular cross-sectional preforms were fabricated. The preforms have five sets of yarn: these are warp, filling, Z-yarn and {+-}45{degree} yarns. The preforms which are made from carbon fibers were consolidated by vacuum impregnation molding at N.C. A and T State University. Epoxy/resin was used as the matrix. The unit cell of the multiaxial 3-D woven structure has been described. Mechanical tests were carried out on multiaxial 3-D woven and orthogonal woven carbon/epoxy composites. The tests included bending, interlaminar shear and in-plane shear. Test results for both structures were compared and are presented.
