Abstract
The present world demands highly advanced engineering materials with unique mechanical and physical properties for most of the structural applications. Scientists and researchers are working hard to develop multifunctional materials to meet the demands of advanced applications. Matrices and reinforcements are the two major building elements of the composites. While the reinforcements pass on extraordinary materials properties to the composite, the matrix holds the reinforcements in their relative situate firmly. The matrices also protect the reinforcements from the external harm such as environmental, mechanical and chemical damages. Composites are broadly categorized as follows based the type of matrices (polymer, metal, and ceramics) and the geometry of reinforcements (particulate, flake, and fibers). The most widerly used advanced composites in the light weight applications such as aircrafts, spacecrafts, marine and sports equipmentâs are polymer matrix-based composites (PMCâs). Polymers such as epoxy, phenolic and acrylic polyester etc. are used as matrices in the PMCâs. The reasons why they are most widely recognized in many applications include their simple processing methods along with their outstanding specific strength and stiffness properties. This work reviews the structure, classification, manufacturing techniques and applications of the currently existing Fiber reinforced polymer.
Highlights
INTRODUCTIONFiber reinforced plastics are made from polymer matrix reinforced with fibers
FRP composites plays an important role in civil engineering applications as they are having high strength, high stiffness and they can withstand high weight ratios, they are highly corrosive resist in nature
Fiber-reinforced polymer-based composites are a class of advanced engineering materials exhibiting excellent mechanical properties even compared to most of the metallic materials available for structural applications
Summary
Fiber reinforced plastics are made from polymer matrix reinforced with fibers. The definition of the Laminates is, it is the Structural application of Fiber reinforced composites. Development of FRP when compared to ancient times as been grown rapidly. They even substituted for traditional materials by their advance in the quality and art [3]. The main functions of fibers are providing stiffens, strength high stability, FRP are frequently used to provide initiative and rational solutions to resolve the developing ageing issue in reinforced concrete structural elements [4]. The main purpose pf FRP’s are to strengthen, and reinforce structures are normally strong, rated 8 times robust than classical steel reinforced bar. It requires lot of information to write about FRP composites [6]
