  • 2. WHAT IS COMPOSITES?COMPOSITES:-- Composite materials (also calledcomposition materials or shortened tocomposites) are materials made from two or moreconstituent materials with significantly differentphysical or chemical properties, that when combined,produce a material with characteristics different fromthe individual components. The individualcomponents remain separate and distinct within thefinished structure.
  • 3. TYPES OF COMPOSITES:-There are several different types of composites used today.The most common are:1. Fibre reinforced composites2. Particulate reinforced compositesThese types of composites cover a range of differentmaterial combinations. The most common type is polymermatrix composites, however, metal matrix composites,and ceramic matrix composites are also common, as arenatural composites such as wood. FIBRE REINFORCED COMPOSITES PARTICULATE REINFORCED COMPOSITES
  • 4. REINFORCEMENTS & ITS ROLE IN COMPOSITESThe primary function of fibers or reinforcements is to carry loadalong the length of the fiber to provide strength and stiffness in onedirection. Reinforcements can be oriented to provide tailoredproperties in the direction of the loads imparted on the end product.Reinforcements can be both natural and man-made.MATRIX & ITS ROLE IN COMPOSITESTo bind the fibers together so that the applied stress is distributedamong the fibers .To protect the surface of the fibers from beingdamaged and to separate the fibers and inhibit crack propagation.ROLE OF INTERFACEInterface plays an important role on coupling between fibre & matrix.It also developes the strength of the composites.
  • 5. TYPES OF FIBRES USED IN COMPOSITES There are mainly three types of fibre used in composites.They are: Glass Fibre, Carbon Fibre & Aramid Fibre. These fibres are used for having some important properties. They are asfollows:1. High tensile and compressive strength.2. Low density.3. High chemical stability.4. High thermal stability .• In case of fabric composites we mainly use the WOVEN FABRICS.Woven fabrics are generally used in high-performance composites toreinforce them. A wide range of different types of woven fabrics are used,the most familiar being plain weave, twill weave and satin weave. Thedensity of the fibre and the type of weave critically influence the formingproperties and the characteristics of the finished product.

  • 7. ADVANTAGES & DISADVANTAGES:-ADVANTAGES:-A higher performance for a given weight leads to fuel savings.Excellent strength-to-weight and stiffness-to-weight ratios can beachieved by composite materials.Laminate patterns and ply buildup in a part can be tailored to give therequired mechanical properties in various directions.Production cost is reduced. Composites may be made by a wide rangeof processes.Composites offer excellent resistance to corrosion, chemical attack,and outdoor weathering.DISADVANTAGES:-Composites are more brittle than wrought metals and thus are moreeasily damaged.Hot curing is necessary in many cases, requiring special equipment.Repair at the original cure temperature requires tooling and pressure.
