Introduction
Composite materials are engineered materials made from two or more different materials with distinct physical and chemical properties. The combination of materials creates a material with improved properties compared to the individual components. The different materials are combined in a matrix, which acts as a binder and distributes the load between the reinforcing fibers. In this article, we will review key developments and applications of composite materials and matrices.
Types of Composite Materials
Composite materials can be classified based on the type of matrix and fibers used. The three main types of composite materials are polymer matrix composites, metal matrix composites, and ceramic matrix composites.
Polymer Matrix Composites (PMCs)
Polymer matrix composites (PMCs) are composites made from a polymer matrix and reinforcing fibers. PMCs are lightweight, have high toughness, and are widely used in the aerospace, automotive, and sporting goods industries. Recent developments in PMCs have focused on improving the mechanical properties, such as stiffness and strength, of the composites.
Metal Matrix Composites (MMCs)
Metal matrix composites (MMCs) are composites made from a metal matrix and reinforcing fibers. MMCs have high thermal stability and excellent mechanical properties, making them ideal for use in high-temperature and high-stress applications. Recent developments in MMCs have focused on improving the mechanical properties, such as wear resistance, of the composites.
Ceramic Matrix Composites (CMCs)
Ceramic matrix composites (CMCs) are composites made from a ceramic matrix and reinforcing fibers. CMCs have high thermal stability and excellent mechanical properties, making them ideal for use in high-temperature and high-stress applications. Recent developments in CMCs have focused on improving the thermal properties, such as thermal shock resistance, of the composites.
Applications of Composite Materials
Composite materials have a wide range of applications, including aerospace, automotive, sporting goods, and construction. In the aerospace industry, PMCs and CMCs are used to make lightweight and high-strength structural components, such as fuselages and wings. In the automotive industry, PMCs are used to make lightweight body panels, while MMCs are used to make engine components. In the sporting goods industry, PMCs and MMCs are used to make high-performance equipment, such as golf clubs and tennis rackets. In construction, PMCs are used to make lightweight and durable building components, such as roofs and flooring.
