  • Abstract:
  • Fiber Reinforced Plastic (FRP) composite materials have several unique features. Important among these are the properties of superior specific stiffness and specific strength, and high corrosion and fatigue resistance. In addition, they offer excellent tailorability. Due to these attractive properties the application of composites has spread to almost every engineering field like marine, automobile, aerospace etc.The aim of the paper is to identify a better method of preparing Glass Fiber Reinforced Composite Laminates. Most predominant method of preparing GFRP composite laminates is Hand Lay-up but t has its own redundant properties like more air voids, resin rich or resin starved areas. These flaws are tolerable when it comes to general applications but on the whole, strength properties get affected. Hence an attempt to identify a better method of preparing GFRP composite laminate by adopting rolling concept is tried upon. A test rig to roll laminates was designed and fabricated for this purpose and later on this was used to draw laminates of different reinforcements. The same type of reinforcements was used in the hand lay-ups also with a view to inspect the resin content in the two manufacturing processes.To assess the resin content there are two methods as per ASTM standards namely Acid Digestion test and Matrix Digestion test also called Bunsen burner test. The latter was opted because of its simplicity, ease of testing and Acid Digestion test is particularly for Kevlar Fiber reinforced laminates as this fiber gets burnt off in a Bunsen burner.
