    Internal structure, mechanical properties and damage behaviour of non-crimp 3D orthogonal woven composites
    (World Acad Union-World Acad Press, 2010) Lomov, Stepan Vladimirovitch; Bogdanovich, Alexander E.; Mungolav, Dimitri D.; Verpoest, I.; Karahan, Mehmet; Teknik Bilimler Meslek Yüksekokulu; Tekstil, Giyim, Ayakkabı ve Deri Bölümü; AAK-4298-2021; 8649952500
    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.
