"Internal structure, mechanical properties and damage behaviour of non-crimp 3D orthogonal woven composites". ed. Chen, X. Hearle, J. Xu, W.

World Conference on 3D Fabrics and their Applications’da bildiri olarak sunulmuştur.The paper presents the results of a thorough study of internal structure and mechanical behavior of non-crimp 3D orthogonal woven carbon/epoxy composites. The following parameters and phenomena are investigated: -internal geometry of the reinforcement: shape of the yarns, waviness, dimensions and shape of the cross sections, and fiber volume fraction inside the yarns; -stiffness and strength of the composites; -non-Hookean effects (stiffening of the carbon fibers with increasing strain) -damage initiation and development monitored by means of acoustic emission -crack morphology at different stages of loading studied with X-ray and optical microscopy; -tension-tension fatigue: S-N curves and damage development with increasing number of cycles.eninfo:eu-repo/semantics/closedAccess3D woven compositesTensionFatigueTensile propertiesWeaveMaterials scienceAcousticsCarbon fibersCompositesDamageEmissionMicroscopyThree dimensional designWeavingWoven fabricYarnAcoustic emission testingCarbon fibersComposite materialsFatigue damageFatigue of materialsMechanical propertiesOptical microscopyThree dimensional3D orthogonal3D orthogonal woven compositeCarbon/epoxy compositesCrack morphologyCross sectionDamage behaviourDamage developmentDamage initiationFiber volume fractionsInternal geometryInternal structureMechanical behaviorNumber of cyclesS-N curveTension-tensionInternal structure, mechanical properties and damage behaviour of non-crimp 3D orthogonal woven compositesProceedings Paper0003941928000252-s2.0-84855604114136141Materials science, multidisciplinaryMaterials science, textilesBraided Composites; Braiding; Damage
