Overview

Demonstrates improved mechanical and ablation performance in carbon fiber-reinforced SiC composites via interfacial design.

Key Points

  • To explore an in-situ interfacial design strategy for enhancing carbon fiber-reinforced SiC composites.
  • Utilized three additive systems for composite fabrication: Al2O3-Y2O3, Al4C3-B4C-C, and Al-B-C.
  • Applied spark plasma sintering at temperatures of 1700 °C, 1750 °C, and 1800 °C.
  • Conducted comprehensive characterization to analyze interfacial reaction mechanisms and performance.
  • Identified 1750 °C as the optimal sintering temperature with >92% relative density.
  • Achieved interfacial strength of 162 MPa with high porosity and poor ablation resistance.
  • The Al-B-C system yielded the best flexural strength (353 ± 9 MPa) and ablation resistance (R_m = 0.12 mg/s).
