Abstract Now a day in all sector weight reduction is most important criteria for lowering the cost & high performance. For weight reduction composite material is good option to solve weight related problems. In this paper we describe analysis of composite glass fibre material with mild steel material comparison. For analysis purpose we can use FEA software. The objective of this paper is compare things like different loading conditions stress distribution etc.

INTRODUCTION

Today composite materials have changed all the engineering material [09]. A composite material defined as a mixture of two or more materials (reinforcement, fillers and binder) different in composition. Composite materials also called composition materials.

The evolution of composite materials has given an opportunity to various designers to use new and better materials resulting in cost reduction, increase in efficiency and better utilization of available resources. Composite materials have large areas of applications in aerospace industry, automobile sector, manufacturing industries, chemical industries, in sports, in electrical field etc. The composite materials are well known by their excellent combination of high structural stiffness and low weight. This work considers the behaviour of components manufacturing from fibre reinforced composite materials. The mechanical behaviours of fibre reinforced composites are primarily dependent on their inherent abilities to enable stress transfer which in turn depends on the fibre strength and matrix strength. Glass fibres (GFs) have been employed in various forms such as longitudinal and distinct fibre. The properties of such composites was however dependent on the nature and orientation of the fibres laid during composite preparation. Glass fibres are one of the most widely used polymer reinforcements with nearly 90% of all FRPs made of glass fibres.

The oldest and the most popular form is the E-glass or electrical grade glass. Other types of glass fibres include A-glass or alkali glass, C-glass or chemical resistant glass, and the high strength R-glass or S-glass. The main advantage of Glass fibre over others is its low cost. It has high strength, high chemical resistance and good insulating properties [10]. In this dissertation work, stress distribution of composite beam with metal beam with different support conditions. Will be analysed for experimental verification by using software analysis comparison of stress distribution of both will be done.

II. LITERATURE REVIEW Many researches across the world have carried large number of investigations and experiments with composite materials instead of metal. As experimentation on composite materials is costly affair, the research has forced towards experimentation on stress distribution of composite beams with metal beams with different support conditions.

Minakshi Vaghani et al. [1] had reviewed on steel alloys and briefly discusses the important properties and commercial aspects of these alloys relevant to structural designers. Recent development particularly with respect to available alloys and its area of applications.

Govart et al. [2] investigated the time dependent failure behaviour of loaded composites, assuming that fracture is gentry dominated. Since the stress and strain state of the matrix Composite Fractures is complex, the yield and fracture behaviour of a neat epoxy system is investigated under various multi- axial loading conditions.

Eslimy – Isfahany et al. [3] described applications of composite materials to several types of structures. For the classical Laminate Theory (CLT) the stiffness of the component can be changed according to stacking sequence (Tsai and Hahn, 1980), which allows for the tailoring of the material without changing its geometry drastically or increasing its weight.

Experimental Verification & Validation of Stress Distribution of Composite Beam with Metal Beam with Different Support Conditions (J4R/ Volume 04 / Issue 02 / 002)

Guru raja et al. [4] had reviewed on recent applications and future scope of hybrid composites. This paper presents a review of the hybrid composite materials technology now a day, in terms of materials available and properties, and an outline of some of the obvious, trends and speculative, with emphasis on various applications including some details of smart hybrid composites. Author concluded the application of hybrid composite in automotive, aerospace, marine, wind power etc.

Hargude et al. [5] discussed about composite material mono leaf spring. In this paper we have understand it is possible to easy manufacturing a leaf spring using E glass epoxy glass fibre. As per the point of weight reduction it is possible by using composite material. Ride comfort and life of composite leaf springs are also more when compared to steel leaf springs.

Kuraishi et al. [6] investigated the composite panels are tested under different tests. The tests that were performed for this study are bending, tensile tests and beam- twist coupling tests. The material properties of interest were basic longitudinal and transverse stiffness and strength, residual stress due to curing and the effects of bend, twist coupling.

S.H. Alsayed et al. [7] investigated the Performance analysis of glass FRP bars as a reinforcing material for concrete structures.

The increasing use of fibre reinforced plastic bars to reinforce concrete structures necessitates the need for developing a new design code or adopt the current one to account for the engineering characteristics of FRP materials.

III. DISCUSSIONS In this review paper we studied the composite material as the complete replacement of structural steel. Composite material is different in physical and chemical properties, composites compared strong load carrying material is known as reinforcement.

Reinforcement provides stiffness and strength which helps to support structural load. Composite materials do not lose their respective identities but still relate their properties to the product causing from their mixture. The benefits of composite materials have their great stiffness and strength. There are many important and useful properties are low mass, low weight unequalled manufacturing and processing possibilities, composites have less noise and lower vibration transmission than metals at the time of operations. Composite materials have high torsional stiffness and impact properties. It has good corrosion resistance, low electrical conductivity and thermal expansion. Composite parts can eliminate joints and provide simplification and assembly design compared to non-composite metallic parts. The main advantage of Glass fibre over others is its low cost. It has high strength, high chemical resistance and good insulating properties. Due to these properties of composites one can replace the metal parts by using composite material. In this dissertation work, comparison of stress distribution of composite beam with metal beam under same load and with different support conditions. To compare experimental results on stress distribution will be compare with those obtained by FEM software analysis.

IV. CONCLUSION Experimental test will be performed by using strain gauges, reflective polar scope both the composite and metal beam will be tested under tension, and bending and torsion test and test will be performed under different support condition. Composite beam and metal beam stress distribution for different supporting condition will be analyzed by using software analysis. To compare experimental results on stress distribution will be compare with those obtained by FEM using software analysis.
