Crack bridging is a toughening mechanism in composite materials where fibers or particles span across cracks, preventing them from opening further and enhancing the material's fracture resistance. This mechanism is critical in improving the durability and longevity of materials subjected to mechanical stress, such as ceramics and advanced composites.

Crack Bridging

Toughening mechanism

Composite materials are engineered from two or more constituent materials with significantly different physical or chemical properties, which remain distinct within the finished structure. They are designed to achieve superior performance characteristics such as increased strength, reduced weight, or enhanced durability compared to traditional materials.

Mechanical stress is the internal force per unit area within materials that arises from externally applied forces, temperature changes, or deformation. It is a critical factor in engineering and materials science, as it determines the strength, ductility, and failure characteristics of materials under load.

Mechanical Stress

Ceramics are non-metallic, inorganic materials that are typically crystalline in nature and are formed through the application of heat. They are known for their hardness, brittleness, and resistance to heat and chemical erosion, making them essential in both traditional applications like pottery and advanced technologies such as aerospace and electronics.

Ceramics

Advanced composites are engineered materials made from two or more constituent materials with significantly different physical or chemical properties, which remain separate and distinct within the finished structure, providing superior strength-to-weight ratios and enhanced performance characteristics. They are crucial in industries like aerospace, automotive, and construction for applications requiring lightweight yet strong materials, enabling innovations in design and efficiency.
