Effect of fiber type on the ablation resistance of sharp leading-edge C/C-ZrB2-SiC composites: mesophase pitch carbon fibers vs. PAN-based fibers
To enhance the ablation resistance of sharp leading-edge carbon/carbon (C/C) composites, ZrB2-SiC was introduced into them by a combined technique of vacuum filtration and chemical vapor deposition (CVD). The effect of fiber type, hybrid high thermal conductivity mesophase pitch carbon fiber (CFMP) and PAN-based fibers (CFPAN), on the ablation resistance of the C/C-ZrB2-SiC composites was systematically evaluated under an oxyacetylene flame exposure at a heat flux of 2.38 MW/m2 for 60s. Compared with the C/C-ZrB2-SiC composite reinforced only by CFPAN, the surface temperature of hybrid CFMP/CFPAN-reinforced C/C-ZrB2-SiC composite decreased by ∼386 °C (a 17 % reduction) along with 15 % and 53 % lower mass and linear ablation rates, respectively. The superior ablation resistance is attributed to the efficient heat dissipation, thereby mitigating stagnation point ablation of the sharp leading edge. These findings present a viable strategy for engineering next-generation thermal protection components with excellent oxidation/ablation resistant performance.
期刊介绍:
Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
