Out of those, Glass Fiber Reinforced Polymer (GFRP) composite materials are replaced by many traditional engineering materials owing to their outstanding material properties. According to the application or need sophisticated fabrications of composites has increased enormously. This increase in the development of such materials will become more economical and reliable when manufacturing process is more efficient and durable. Here we used continuous Glass fiber of 430 GSM (Grams per Square Meter) as the reinforcement material and Epofine 230 (CY230) a class of Epoxy polymer as the matrix material. This paper discusses about the fabrication of continuous (uni-directional) SIKA E-Glass Fiber Reinforced Polymeric (GFRP) composites using Vacuum Bag moulding process.

Introduction Invention of composite materials satisfying various design requirements has revolutionized the fields of research and development in material world. All most all the applications where high strength, high stiffness and light weight is required, the composites are preferred. These have very high strength to weight ratio. This property justifies there usage in many domains. A material system composed of two or more components with distinct properties and distinct boundaries is termed as a Composite material or Composite [1]. Composites have long lasting applications in the fields of aerospace, military, marine, wind turbine, sports equipment, automobile, civil structures etc. [2]. Glass fibers are first commercially produced in USA in 1937 and the first GFRP was produced in 1942 [3]. The percentage of FRP composites usage in aircrafts was about 10% in 1990’s and now a days it was around 40%-50% [4]. The tensile and compressive behaviour of composite laminates is studied over the past decades. But fatigue in composite structures is a very complex phenomenon and is completely new area which is still under development [5]. For such testing it is very important to know the material characterisation of the required composite laminate.
