Characterization of Short-Fiber-Reinforced C/SiC with Recycled C-Fibers
This study evaluates the suitability of recycled carbon fibers (rCF) as reinforcement material in short fiber-reinforced C/C-SiC ceramics. The composite was fabricated using industrially recycled carbon fibers and a phenolic resin as matrix precursor at a fiber volume content of 50 %. Samples were processed via liquid silicon infiltration (LSI). Characterization included microstructural analysis using ceramic cross-sections and digital microscopy, as well as mechanical testing through three-point bending tests according to DIN EN 658-3. The commercial reference material FU 2952/9 P77 from Schunk Carbon Technology was used for comparison. Results indicate that the rCF-based composite achieves a comparable average flexural strength of 49.5 MPa to the industrial reference material. Typical fiber-reinforced ceramic features such as damage tolerance and fiber pull-out were confirmed. The study highlights the potential of recycled carbon fibers for sustainable high-performance composite materials
