Abstract: Composite materials, plastics and ceramics have been the dominant emerging materials from last thirty years. Polymeric materials reinforced with natural and synthetic fibres such as coconut, bamboo, jute glass, carbon and aramid provide advantages of high stiffness, good thermal, acoustic insulating properties, excellent formability and strength to weight ratio as compared to conventional construction materials, i.e. wood, concrete, iron and steel. The increase interest in using natural fibres as reinforcement in plastics is to substitute the conventional synthetic fibres in some structural applications and it has become one of the main concerns to study the potential of using natural fibres as reinforcement for polymers. In this research paper, seven different fiber reinforcement polymer composite were fabricated by wet hand-lay-up method using short coconut, short bamboo and short glass fibers binded with amino resin like urea formaldehyde. The urea formaldehyde was selected due to its low cost, less weight, easier to field fabricate, long durability and high temperature withstand ability. The different mechanical properties like density, tensile strength, hardness, flexural strength and percentage elongation of specimens were calculated and were compared with the pure urea formaldehyde.
