This document discusses a seminar on composite materials for aerospace applications. It begins with an introduction to composite materials, including their classification and advantages. Composites are made of two or more distinct phases (a matrix and dispersed phase) that provide overall superior properties compared to individual components. The document then discusses the different types of composites like particulate reinforced, fiber reinforced, and structural composites. Applications in aerospace are also presented, like usage in Boeing 777 aircraft at 12%. The document concludes that composites will play an increasingly significant role in aerospace due to properties like low weight and high strength.

- 3. Composite material is a material composed of two or more distinct phases(matrix phase and dispersed phase) which are chemically & physically different Composites are used because overall properties of the composites are superior to those of the individual components 3
- 4. 4 The primary phase, having a continuous character , is called matrix. Matrix is usually more ductile and less hard phase. It holds the dispersed phase and shares a load with it. The second phase (or phases) which is embedded in the matrix is called dispersed phase. Dispersed phase is usually stronger than the matrix, therefore it is called reinforcing phase
