Damage and failure mechanisms of a3-directional carbon/carbon composite under uniaxial tensile and shear loads

Tensile strength and fiber/matrix interfacial properties of 2D- and 3D-carbon/carbon composites

“…[6][7][8][9][10][11][12][13][14] The common results obtained by these studies are; the tensile modulus increases and fracture strain decreases with increasing the final heat treatment temperature (HTT) up to 2500 • C, and the tensile strength and modulus increases with increasing the bulk density. These conclusions were seemed to be drawn only from experimental evidences without any clear understanding of fracture mechanics.…”

“…The present study about threedimensionally fiber-reinforced C/Cs (3D-C/Cs) has done within this framework study. One of the characteristics of laminate (2D-) C/Cs is poor interlaminar shear strength (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) MPa) that comes from lack of reinforcement in the thickness direction. Thus, 2D-C/Cs can be applied to the structures that sustain only in-plane stress field.…”

Hierarchically modeling the elastic properties of 2D needled carbon/carbon composites

“…The microstructural characteristics and mechanical properties of 2D, 2.5D and 3D C/C composites have been extensively studied [3][4][5][6][7][8][9]. One of the characteristics of 2D laminated C/C composites is poor inter-laminar performance that comes from lack of reinforcement in the thickness direction.…”

Finite element analysis for mechanical characterization of 4D inplane carbon/carbon composite with imperfect microstructure

“…These composites have significant damage induced during the manufacturing process (Jortner (1986), Sharma (2012), Siron (1998)). Damage in the form of matrix cracking, debonding of fiber/matrix and fiber bundle/matrix interfaces occurring during manufacturing, affects the properties adversely (Sharma (2012), Rao (2008) ab ).…”
