Effect of AA6061 on Mechanical Properties of Basalt Fiber Reinforced Vinyl Ester Resin by Using Hand Layup Process

Abstract

In this research work, thermo-set polymer hybrid compound was manufactured by using vinyl ester resin. In this study, vinyl ester resin is utilized as a matrix material. Introduce to study, an AA 6061 particulate filler is added with weight ratio of (0, 5, 10, 15) and basalt fiber (330 gsm) is arranged one on other, hand layup procedure is used to prepare a composite objects. These composite materials are cut in to the test specimen’s as per the ASTM standards. The mechanical properties like tensile, impact, and flexural strength are calculated according to the ASTM standards. In this work, composite with filler materials shows superior mechanical properties than the material without filler materials. The effects of AA6061 on mechanical properties of basalt fiber reinforced vinyl ester resin are studied from the experiment results. It has considerable effect on the mechanical properties of the composite material. In particular, a comprehensive SEM examination of the damaged sample surfaces has been undertaken to find out bonding between AA6061 filler, matrix and reinforcement.

Introduction

I. INTRODUCTION

The conservative materials are restricted to specific material properties; this circumstance leads to found composite materials. In present situation composite materials are replacing the places which are occupied by the conventional materials for several years in the manufacturing world. By adding two or more materials we can change the properties of the material. In fact the above definition is about the composite materials and an Alloy. In composite materials we can easily identify the material placement but it is not possible in the case of an alloy. The composite material has good mechanical, thermal and electrical resistance properties compared with the traditional material. The properties of the composite material are different in every direction so they are known as an anisotropic material. This materials are vitally grouped in to PMC, CMC, and MMC among them polymer matrix composite is widely used because of their easy maintenance and low cost of production.

The Polymers are classified in to thermo-set and thermoplastic polymers materials. Due to their promising strengthening system the FRP’s are replacing the  traditional materials like  steel.  Fiber reinforced polymers (FRP) has enhanced mechanical and chemical properties. It is precise that despite of high tensile and flexure strength, structures which are made with FRP can be failed in brittle manner due to their weak bonding nature between resin, fibers and filler materials. To overcome this type of situation, perfect bonding between the materials is required. For the applications which required high strength uses carbon FRP materials. . On the next hand glass fibers are classified in to E, S, C, etc. The FRP is selected according to the applications.

Basalt fibers are extracted from the basalt rock through melting process. During starting phase of production is does not hold any other additives. A basalt fiber has low water absorption, due to this it is used in construction and pipe applications. Basalt fiber has better tensile strength than the E-glass fiber. Basalt fiber can absorb more energy compared to carbon and glass fibers. It has enhanced resistance against chemical attack, impact load, and fire with less poisonous fumes.

A. Objective Of The Current Work

The main purpose of the current research work is to check the effect of AA6061on composite material. To research the mechanical properties like tensile, flexural and impact by adding required proportions of AA6061 filler to the composite material.

Compared with the hybrid composites the material with filler has the better properties and can get complex shapes.

III. MATERIALS AND METHODS TO BE USED

A. Materials Used

Vinyl ester resin is collected from VRUKSHA COMPOSITES CHENNAI. It is a blend of epoxy and polyester. Vinyl ester linkages are formed by the reaction of unsaturated carboxylic acid with an epoxy resin by removing the byproduct of water. These materials are more elastic and have better mechanical properties such as good adhesion with glass fibers, excellent wet out after solidification and compared to polyester, resin low volumetric shrinkages are produced.

The accelerators, catalyst and promoter act as one type of curing agents .These agents are added to vinyl ester resin which helps to initiates the chemical reaction.

The basalt fiber is supplied by VRUKSHA COMPOSITES CHENNAI .These basalt reinforced material is mainly used in construction industries, due to its higher impact resistance capabilities. Basalt rebar are easily available and it has low cost compared to carbon and invar materials which are very famous for their strength. Graph of the properties like impact, electric, heat resistance of basalt fiber are in the middle of the carbon and glass fiber. This is the main reason to choose basalt fiber (330 gsm) for this project.

AA6061 (Aluminum Alloy) which is collected from VRUKSHA COMPOSITES CHENNAI.  It acts as filler material in composite which provides strength to the component. AA 6061 is an alloy which has magnesium and silicon as major components in its composition. This filler material has better mechanical properties, which can support basalt fiber during heavy load apply on it. It has good thermal and electrical resistance properties. It provides good adhesion between reinforcement and matrix material to improve hardness of the laminates. The laminates which are prepared are mostly preferred in high impact resistance applications.

Conclusion

In this research work, I probed how varying percentages of AA6061 filler affects the mechanical assets of basalt fiber reinforced vinyl ester resin composites. Following conclusions are made from this study. 1) Impact strength of basalt fiber reinforced composites is getting decreased by increasing the filler percentages. 2) Increasing filler in the composite can reduce the bonding between the compounds. 3) Highest tensile and flexural strength is obtained at 10% addition of filler to the composite. 4) Inter laminar toughness is getting increased by increasing filler percentage to the composite.
