Bending Properties of 3D Integrated Woven Spacer Composites with Hybrid Carbon/Glass Fiber
The face sheets of three-dimensional (3D) integrated woven spacer fabric have an important influence on the bending properties of the spacer fabric composites.The 3D integrated woven spacer composites with different ratios of carbon/glass fibers in the surface layers are designed and prepared.The bending properties of spacer composites with hybrid different content of carbon fibers are examined.Macroscopic morphology and microscopic morphology are studied to understand the fracture and failure mechanisms.The results indicate that the bending properties of the spacer composites are significantly affected by the carbon fibers that are intermingled into the surface layers.Compared to the spacer composites with pure glass fibers, as the carbon fiber content increases, the bending modulus increases by 14.82%, 17.49%, 37.39%, 46.18% and 51.11%, respectively, while the bending stiffness increases by 26.30%, 26.25%, 54.58%, 61.75%, 68.05% and 74.80%, respectively.The deformation and fracture of the compression face sheets are the main failure mode of the spacer composite.There is no visible deformation or fracture in the tension face sheets and the pile yarns.Linear elastic stages and brittle fractures are obviously observed during the bending process.The interfacial bonding performance of carbon fibers and resin is poor, and the fracture sections of carbon fiber yarns are uneven, and the phenomenon of delamination, degumming and extraction is prone to occur.Hence, the interracial binding performance needs to be further improved.
