to a shift towards the use of the most suitable composite materials instead of steel for roofing. Researchers are currently studying and developing materials that shows the necessary properties while also being environmentally friendly. Natural fiber composites, which reveal similar properties to synthetic fibers, are being integrate with a matrix to produce ideal results. The hybrid composite materials are a mixture of natural and synthetic fibers which are each in same proportion ratio to have desired properties. This present research work deals with the study mechanical properties of basalt fiber mat composites having bamboo fibers pulps and glass fiber to which reinforced with epoxy resin as the matrix. In this work we are carrying tensile test and flexural test and Hardness test to evaluate the mechanical properties of composite roof sheet. and analysis of heat flux compared with original roof material with natural fibers. The Hybrid composites resulted in enhanced mechanical properties for the overall structure when compared to the original roof material.
Composite materials were first used in the aerospace industry in the 1970s, but they are now used in almost every industry after only three decades. Meanwhile, the automotive sector, which is regarding the industry in each country, has profited from the capabilities and properties of these modern materials. Metallic parts are being phased out in favour of composites as technology advances. Properties of Composite materials 1. Materials made from composites exhibit mechanical characteristics where the tensile stress is 4-6 times greater than that of conventional materials such as steel and aluminum.
Key Words: Composite Materials, Design, Mechanical Properties, Natural Fiber.
2. The tensile strength and stiffness of the composite matrix are far superior.
1.INTRODUCTION
3. It is capable of enduring significant deformation.
The combining of the physical as well as the chemical properties of more than one materials occur as a result, the material has features that are distinct from the separate components. Particular units rely on being distinct and divides in the last module, that separates composites from being mixes and solid mixture. It combines to provide features that are superior to the separate elements properties. Matrix and filler/fiber are the two components of composite material (reinforcing phase). Fibers, sheets, and particles can all be used to strengthen different phases. The matrix phase surrounds it. In the production of composites, metals, ceramics, non-metals, and polymers can be employed as reinforcing and matrix materials. The composite fiber is stiffer and stronger than the matrix material which serves as load bearing components. The load transfer medium between fibers/fillers is the composite's continuous phase (matrix). Because the matrix is more ductile than the fibers, it provides toughness. When examined in adequate detail, all materials are made up of distinct subunits, hence the phrase composite could mean practically anything if taken at face value. Composite materials are heavily being used in the

4. Composites are, on average, 30–45 percent more costeffective than aluminum structures with similar features. 5. Compounds composed of various elements. 6. It also requires less energy to be embedded. 7. Composites generate lower levels of vibrations during operation. 8. The materials are also significantly more flexible.
2. LITERATURE REVIEW Rami Eid [4] has conducted tests on six FRPTRP-encased reinforced concrete columns subjected to compressive axial forces and examined the performance of circular, square, and rectangular columns. The more FRP layers present, the greater the compressive strength of the concrete, along with the associated strain, which is extensively documented in the existing literature. of Marijn R. et al., (1999), Laura De Lorenzis et al., (2003), Silvia Rocca et al., (2008).
