The conflict of targets between mass reduction, strength and costs of a multi-material-design module is addressed by the example of a multi-material hybrid leaf spring. A rather simple model is defined such that one portion of the spring is made by glass fiber reinforced plastic (GFRP) and the other portion by a high strength spring steel.In a rather basic approach the leaf spring is exposed to uniaxial bending. The mass of this module is discussed as a function of the strength of the joint. Subsequently, the leaf spring is exposed to a multi-axial bending, e.g. as an effect of side loads. Hence, the relative strength of the anisotropic portion (GFRP) of the leaf spring is diminished whereas the strength of the isotropic portion (high strength spring steel) is only slightly affected. The mass of the module is discussed in the same way. It is shown up by this analysis that the conflict of targets can be solved in different ways by considering the specific strength of the joint.It is the target of this basic study to derive the mechanical requirement of strength of this tailored joint which has to be met by its design in order to solve the addressed conflict of targets in a preferable optimal way.

The automobile industry has shown an increased interest in the use of composite leaf springs due to their high strength to weight ratio. The introduction of composite materials has made it possible to reduce the weight of the leaf spring without any reduction in load carrying capacity and stiffness. In this paper, the results of research on fatigue life of composite (Glass Fiber Reinforced plastic – GFRP) leaf springs are presented. Composite springs were designed in such a way that they could replace steel springs in a van.

Car segments have an expanding rivalry in the market and it will in general create development in the current items by either succeed with another or altered propelled material items. A suspension framework is one of the most intriguing push territories on vehicle structure. This task effort is worried about the plan and investigation of mechanical portrayal of leaf springs that are in effect despite everything utilized generally in cars as suspension segments. Car makers have the due significance on enhancement for the mileage of the vehicle which thusly on a structure perspective the weight decrease is the most concerned one. There by the strength-weight proportion idea has been created and composite material is executed. The utilization of composite leaf spring rather than ordinary steel leaf spring is favored for the examination due to its high solidarity to weight proportion. It is made convincing to decrease the weight of the leaf spring without relinquishing the solidness and burden conveying limit of the spring by the usage of composite materials. The target of this task work is the plan and examination of the exhibition qualities of Glass Fiber Reinforced plastic (GFRP) with iron powder as a composite leaf spring and correlation with traditional leaf spring. The composite example is created utilizing hand layup technique. Exploratory work have been completed an all Universal Testing Machine for the composite and ordinary steel leaf spring and approved with the ANSYS investigation. The investigation results are connected so near test.

Increasing competition and innovation in automobile sector tends to modify the existing products or replace old products by new and advanced material products. A suspension system of vehicle is also an area where these innovations are carried out regularly. Now days the automobile Industry has shown much interest in using Fiber Reinforced Plastic (FRP) components replacing conventional steel components due to its “high strength to low weight” ratio. Therefore replacement the steel open coil suspension springs (in heavy automobiles) with Glass Fiber Reinforced Plastic (GFRP) open coil springs with the main aim to reduce its weight and thereby reduce the fuel consumption to some extent. A semi mechanized pultrusion process (E –Glass and Epoxy Resin) and braiding process is selected for fabricating the GFRP open coil springs. It is then tested in lab to study some of the variable parameters. Keywords: Fiber reinforced plastic (FRP) , Coil spring , Pultrusion

Although leaf springs are one of the oldest suspension components, they are still frequently used in the automobile vehicles. Weight reduction is the main focus in the automobile industries. Weight reduction can be achieved primarily by the introduction of better materials, design optimization, and better manufacturing processes. The achievement of weight reduction with adequate improvement of mechanical properties has made composite a very good replacement material for conventional steel. Selection of material is based on the cost and strength of material. The composite materials have more elastic strain energy, storage capacity and high strength to weight ratio compared to steel. This paper briefs about the research carried out for the part of three decades on design, analysis, and selection of material, experiments and fabrication of composite leaf spring.

Research And Design

Recently, Fiber Reinforced Composite is used for making a propeller blade to develop its performance by increasing the payload and underwater speed of the vehicle. As a consequence of its feathery weight & high strength, numerous scholars/scientist substituted the conventional metallic material with composite material for crafting the propeller. In the contemporaneous work, predictions of pressure circulation around the profile of a propeller blade as a result of hydrostatic pressure difference are existing. Static structural stress investigation was executed for a single combination i.e. carbon fiber reinforced plastic (CFRP) & for hybrid condensation (a combination of two composite materials) i.e. CFRP & Glass Fiber Reinforced Plastic (GFRP). ANSYS APDL software is used to conclude von Mises pressure developed in the propeller blade. The result has been given away that it is more beneficial to use the hybrid blended material than the composite one. The weight value of propeller blade is found to be lower for the hybrid complexes, proposing the intrinsic worth of the contemporaneous work.
