“A Review of Composite Material for Aligning It’s Characteristics Behaviour to Enhance it’s Use in Engineering Applications.”
Composite material is a material made from two or more constituent materials or Viscoelastic Materials (VEM) with significantly different physical or chemical properties that, when combined; produce a material with characteristics different from the individual components. Typical engineered composite materials include: Composite building materials, such as cements, concrete, Reinforced plastics such as fiber-reinforced polymer, Metal composites.
The use of composite material for advanced engineering applications makes it imperative to assess its behaviour in the scope and domain of NVH. In cases, where the occurrence of resonance is undesired for the function, the same needs to be negated by controlling the influential parameters leading to the characteristics of vibration for the component or the sub-assembly. The first mode and the others that follow indicate the natural frequencies at which the response of the material tends to be higher. The tendency to resonate over the operating frequency or working range could be controlled by altering the Eigen value by assigning a different level for control parameters. The mass, stiffness and damping could be varied to realize suitable Eigen value and Eigen vector for the function.
