The present-day industries require more complex products for multi engineering domains. Scientists and researchers are continuously searching for new methods for making products with low density, high strength, and high stiffness to weight ratio, excellent durability and design flexibility. The GFRP composites is an unique material which satisfies all the pre-requisites of the fields such as aircraft, automotive, marine and other industries that need many structural components. There are several manufacturing techniques employed to make GFRP composites. This project investigates the mechanical behavior of GFRP composites using Vacuum Assisted Resin Transfer Molding and Hand Laying Technique. This method is considers as simple manufacturing method, because during the HLU process, the mechanical properties and dimensional stability are poor and hazardous air pollutants may be emitted. The VARTM is becoming more popular due to its low hazardous emissions and high mechanical properties and dimensional stability. VARTM-WRM 45 degree has 4.25% high tensile strength, 7% high impact strength compared to HLU-WRM 45 degree. VARTM-CSM 0 degree has 7.18% high tensile strength, 6.9% high impact strength compared to HLU-CSM 0 degree.
