“…Tribological behaviour of C/C and C/C-SiC composites also depend on the counter surface material to a greater extent [6,14]. Many researchers [15][16][17][18] had investigated the tribological behaviour of C/C and C/C-SiC composites using parallel orientation of laminates in self-mated pairs. Surface conformity also effects the tribological behaviour of materials.…”

Tribological behaviour of composites depend upon the surface conformity of interacting surfaces, local friction and wear response, and interaction area proportion of its constituents. Several other factors like wear debris interaction with the contact surfaces, and braking energy are also involved during in-service conditions. For laminated composites, interaction area proportion and wear debris interaction change with the orientation of laminates, due to change in surface conditions. Earlier research on tribological behaviour of carbon/carbon (C/C) and carbon/carbon-silicon carbide (C/C-SiC) composites mostly dealt with the parallel orientation of the laminates, and fully conformal surfaces. Thus, present article aims to investigate the tribological behaviour of C/C and C/C-SiC composites with variation of laminate orientation, surface conformity, normal load and sliding velocity. Normal and parallel orientation of laminates were considered with low and non–conformal Hertzian contacts. Worn surfaces were analysed under scanning electron microscope. The results show more fluctuations in friction coefficient (COF) for normal orientation of laminates. C/C-SiC composites loaded with parallel orientation of laminates generally exhibited highest COF and lowest wear loss. COF and wear loss decreased in non-conformal Hertzian contacts when compared with low conformity contacts and the reduction was large for C/C composites as compared to C/C-SiC composites.

“…Developments in these applications will place higher requirements on these materials, and there is a need to find effective ways to improve their properties. A universally recognized method to optimize material properties is through the control of microstructure [10][11][12]. However, C/C-SiC composites have complex three-dimensional spatially distributed structures that contain varying fractions of residual C, formed SiC, residual Si and porosity, which depend on the original carbon fiber architectures and fabrication conditions.…”

Microstructure Characterization by X-Ray Computed Tomography of C/C-SiC Ceramic Composites Fabricated with Different Carbon Fiber Architectures

The microstructure morphologies have been characterized by high resolution laboratory X-ray computed tomography in Carbon Fiber Reinforced Carbon and Silicon Carbide (C/C-SiC) ceramic composites fabricated by Gaseous Silicon Infiltration (GSI) from C/C preforms of three different architectures: 3D stitched cloth fabric; 3D orthogonal woven fabric; and needled shortcut felt. Each composites' microstructure was influenced by the structure of the C/C preform. By incorporating tomography with gravimetric analysis, the 3D distribution of the SiC was visualized, showing a connected SiC network in the needled shortcut felt, and more heterogeneous SiC formation on the surfaces of the fiber bundles in the stitched and woven fabrics. The needled shortcut felt provided the largest contact surface for the GSI reaction and generated~56% volume fraction of SiC, which is almost twice and three times that achieved in the stitched and woven fabrics respectively. Differences in the open and closed pore distributions were also measured by mercury intrusion porosimetry and tomography.

“…Because of their superior mechanical, physical and chemical properties, carbon fiber reinforced carbon and silicon carbide composites (C/C-SiC) has been proposed as materials for aerospace structural [1], advanced friction [2] and space mirror systems [3], and also for advanced nuclear energy [4] and ballistic protection [5]. There are three frequently used preparation methods for C/C-SiC composites: Chemical Vapor Infiltration (CVI), Precursor Infiltration and Pyrolysis (PIP) and Silicon Infiltration (SI) [6][7][8][9]. The SI methods include Liquid Silicon Infiltration (LSI) [10] and Gaseous Silicon Infiltration (GSI) [11].…”

3D needled carbon fiber reinforced composites (C/C-SiC) were fabricated by gaseous silicon infiltration (GSI) for different reaction times, followed by further densification with liquid silicon infiltration (LSI). The density, flexural modulus and flexural strength increased as a spatially connected SiC structure developed, but the flexural strength could be degraded by a long total reaction time. The composites all exhibited quasi-brittle fracture with fiber bundle pull-out and interfacial debonding. Fracture could propagate within the needle bundles that were perpendicular to the tensile stress.
