INTRODUCTIONIn today’s world, the material science is not a only minor discipline but now its becomes a fundamental foundation of innovative technologies and modern construction techniques. Material indulges in all extensive fields like telecommunication, construction engineering, medical science, mechanical and many others (Askeland and Phulé 2006). In all field of sciences, material come up with innovative techniques and became these field more modern. Theresearch of material science depends on the quality of the researchers whether it will be on large, medium or small scale (Ashby and Jones 2005). In this paper, the hot topic of material science will be discussed. Now a days, the modern technology ‘ fiber reinforced plastic’ using in modernconstruction.FIBER REINFORCED PLASTICFiber reinforced plastic is also terms as FRP ( fiber reinforced polymer). The material used for reinforcing that is fiber mixed with polymer matrix made a composite material which is fiber reinforced plastic. Carbon, basalt, asbestos, aramid and sometimes wood may be used as a fibers.Fiber reinforced are mostly used in the fields of marine industry, automotive, civil engineering and aerospace. Fiber reinforced plastic also playing a significant role in civilian industry ( Jacobsand Kilduff 2005).GENERAL CHARACTERISTIC OF FIBER REINFORCED PLASTICFiber reinforced plastic are high in weight and have very high strength. Many industries speciallyautomotive farms are taking so much interest in these composite material and replacing metal parts with FRP’s in cars. Fiber reinforced plastic are very lighter and more capable to consume
less fuel than other metals. Fiber reinforced plastics have potential to modify its properties to cover a broad varieties of requirements. Environmental resistance of high grade, properties of compression and impressive electrical properties all are the characteristics of fiber reinforced plastics. The process of manufacturing of fiber reinforced plastics, which is very effective in costthat is the main significant feature that these composite materials are extensively using in almostevery industry. The productivity rate is high. Different materials can be bond easily.The additional limited characteristics of fiber reinforced plastics are insulation of thermal materials, reliability in structural, hardness in fire with stability in ultraviolet, chemical resistanceand other corrosive material. There are some specific factors on which properties of fiber reinforced plastics are reliant; the comparative volume of matrix and fiber, mechanical propertiesof both of these components and the direction and length of fiber within the matrix. In short, minimum investments in manufacturing, low cost of manufacturing, flexibility, adopt to change conditions of market and speedy entrance in market are the characteristics of fiber reinforced plastic.Many non-reinforced plastics are not suitable or achieved the required strength and young’s modulus of structural designs so fiber reinforced plastics are good choice to gain mechanical strength. The main consideration while designing is the use of material that is economical mainlyenhancement of structures (William and Callister 2007). Material gets weak with the orientation of fiber. The strength of material, its rigidity and elasticity is affected by the fiber reinforced plastics. The flexibility of final product and its strength and elasticity are dependent on the directions of fiber. High distortion resistance of forces occur with the orientation of fibers in the direction of forces. The design and shape of product affects the properties. Many considerations
like proper thickness of wall and proper geometric shapes have considered (Rahul Dogra and Ankit 2016).FIBER REINFORCED PLASTIC AND COMMERCIAL INDUSTRY1n 1930, the UK researcher Norman de Bruyne did extensive research on the expansion of fiber reinforced plastic for the use of commercial industry. Aviation industry is the main point of interest of his research. Russia was the one to create plastic material passenger boat. 1n 1939,wings of air planes and fuselage were made of fiber plastics in united states. The use of fiber thermo set plastic is increasing in commercial industry because of its weight which is very light, less corrosion factor, properties to resist temperature, easy insulation of thermal, smooth, internal surface is very complex shapes can easily be mold, repairing process is easy, and very effective in cost( M cMahon and Jr 2004). All these properties of fiber reinforced plastic affect the commercial industry with positive impact. The best quality of the material is achieved by the techniques of winding and components of fiber glass. Commercially, the most frequently used fiber is fiber glass. Vast area of applications and processes is covered by glass fiber. Fiber glass is made up of raw material which is based on silica mixed with oxides of metal and covering most of the demand of application in almost hundreds of formulation. A tremendous progress of performance and cost is achieved by the shield of fiber reinforced glass and good resistance to chemicals and mechanical properties.There are various available varieties of fiber reinforcement glass like roving of guns, fabrics of textiles, roving of woven, roving with single end and mat with continuous strand. Hence, fiber reinforcement plastic are extensively increasing in commercial industry( Sigma 2007). The properties of fiber reinforcement plastic made it different from other metal in the industry. It has placed the new diversion of vision in commercial industry.
