Ceramic Matrix Composite Material Testing

Fiber-reinforced ceramic matrix composites (CMCs) have significantly improved the inherent brittleness of traditional ceramics by incorporating high-strength, high-modulus fibers into a brittle ceramic matrix. The fibers primarily act to induce mechanisms such as fiber bridging, pull-out, and crack deflection within the material, thereby providing non-catastrophic fracture behavior and greatly enhancing fracture toughness and thermal shock resistance . Currently, CMCs are mainly used in aerospace, gas turbines, and nuclear energy applications. Silicon carbide fiber-reinforced silicon carbide matrix composites (SiC/SiC) are a key focus of current research and development. SiC fibers and SiC matrix possess intrinsic stability in high-temperature, oxidizing environments and extremely high oxidation resistance, making them ideal materials for extreme conditions such as aero-engines and nuclear reactors, though at a very high cost. Currently, advanced CMC preparation technologies are largely monopolized by a few major companies in the United States, Japan, and France, creating certain technical barriers. China has designated CMCs as a critical strategic new material. With strong support from national science and technology programs (such as the "Aero-engine and Gas Turbine Major Project"), China is actively pursuing layout and breakthroughs across the entire technology chain.

Our laboratory has been deeply engaged in the field of CMC testing for over a decade through national-level projects. We have developed a series of testing standards specifically for CMCs and have researched and developed multiple testing equipment systems for CMC characterization. We possess comprehensive testing capabilities for the entire CMC process. The laboratory aims to establish a complete material properties database, provide reliable data for designers, and support the acceleration of material application.

Service Advantages

Deeply engaged in the field of CMC testing for over a decade. We have developed a series of testing standards specifically for CMCs and researched and developed multiple testing equipment systems for characterizing CMC properties under extreme environments. Awarded a Second Prize of National Science and Technology Progress for this equipment.

The laboratory is among the earliest research institutions in China to conduct research in the field of CMCs, having achieved significant research results and accumulated substantial experience in CMC testing. Currently, the laboratory is equipped with dozens of CMC-specific testing instruments and a dedicated composite materials testing laboratory covering over 1,000 square meters, providing comprehensive testing conditions.

As is widely known, CMCs are widely used in aerospace vehicles due to their excellent high-temperature performance and high damage tolerance. In response to mainstream demands, the laboratory has developed systems such as an ultra-high temperature mechanical properties testing system and a high-temperature water vapor/oxygen corrosion testing system. These are designed to provide solutions for evaluating the service performance of vehicles in extreme environments.
