MECHANICAL BEHAVIOUR OF GLASS FIBER/EPOXY MODIFIED WITH NANO COMPOSITES: A REVIEW
Composite material plays a vital role as it is a combination of two or more materials that results in better properties than those of the individual components used. Major proportion of Engineering materials consists of composite materials. Composite materials have been used in vast applications ranging from day-today articles to highly sophisticated applications. In this present investigation glass fiber/epoxy resin modified with nano composite is manufactured by hand layup and compression molding method. The glass fiber used in this investigation is E-glass fiber : orientation(0°-90°). The composite samples are made in the form of laminates and the weight percentage of nano material added to the specimen is varied from 1%wt-7%wt. The specimen made is cut as per ASTM standards for Tensile, Flexural and Impact testing. The results of mechanical properties are analysed and the required specimen is analysed using Ansys software for specified application.
Effect of water absorption on impact strength for epoxy-glass fibers composite
Hand lay-up method was used to prepare sheets of epoxy (EP) reinforced with 12 layers of (0 -90 ) glass fiber mat with volume fraction equal to 30%. The sheets of Ep-glass fiber composite were cut to samples with standard dimensions for charpy impact test. The main objective of this research was to study the effect of water absorption on impact strength for epoxy-12 glass fiber composite. Diffusivity behavior and diffusion coefficient were investigated. The samples were dividing to three groups immersed in distilled water for different time, the first group 15 days ,the second group 27 days and the last 39 days at constant temperature(±20)C the mass gain recorded every 3 days till saturation (M ) after that the mass gain decreased .the results showed that the maximum diffusion coefficient (minimum absorption resistance ) was for sample (A),while the minimum diffusion coefficient (maximum absorption resistance) was for sample (C). The impact strength has been investigated for samples before and after the immersion in distilled water for different time. The results show that the impact strength decreased with increasing the time of immersion for samples.
A Comparative Investigation of Glass Fiber/Epoxy Composites
–The present work describes the development and mechanical characterization of new polymer composites consisting of glass fibrer, epoxy composite with variation in volume fraction. The main objective of this paper is to compare the computational results with analytical methods to determine the mechanical properties like tensile strength, shear strength & hardness. For manufacturing of composites hand layup method is used. The volume fraction is used with 40%, 50%, and 60% in the total composition. The results shows better mechanical properties with 50% of Volume fraction, however further increase in fiber content increases mechanical properties but composites starts delaminating.

The main objective of this work is to study the three samples of glass fibre reinforced with three different ratio of epoxy resin. In this study the different weight percentage of given material properties are identified by using destructive such as tensile test, impact test, hardness measurement and vibration analysis (non-destructive testing method). The main aim of this study to predict the quality of the materials (weight percentage of suitable given materials) using the above test methods. Testing this sample through tensile, hardness, impact, vibration and comparing it by the testing result to find the best among these three-composite sandwiches which are used to some applications.

Composites are an important class of materials available to mankind. Studies of these composites are plays a very important role in material science, metallurgy, chemistry, solid mechanics and engineering applications. The E-glass fiber reinforced polymer composite are more widely used in the automotive industry and other industrial applications, due to their advantages, like low cost, noise control, low weight and ease of processing. Presently very limited work has been done on the mechanical properties of chopped strand mat of E-glass fiber reinforced composites.

The greatest advantage of composite materials is strength and stiffness together with light weight. By choosing an appropriate combination of matrix material and reinforcement, manufacturers can produce a property that exactly matches the requirements for a particular structure for a particular purpose. The present works aims to prepare E- glass fiber reinforced composite with variation in volume fraction of glass fiber content like 1%, 2% and 3% with Bisphenol A as matrix material. Tensile and compression tests are conducted on the prepared composite. As a final point of view, the experimental results are compared with the FEA results by using analysis software like ANSYS

In the present days composite materials are the popular materials in demand because of their high strength to weight ratio. In the present work an attempt has been made to evaluate the Fiber Surface Treatment of Woven Strand Mat (WSM) E-glass fiber reinforced with Epoxy Polymer Matrix Composites. The hand lay-up technique was used to fabricate the epoxy matrix composites reinforced with treated WSM E-glass fibers of volume fraction of 3.42%. WSM E-glass fibers used to evaluate the mechanical properties of the epoxy composites were treated in three different types. First is the manufacturer supplied E-glass fiber coated with lubricating oil and polyvinyl acetate, second is the surface heat treatment and the last one was Ethyl Silicate coating on heat treated E-glass fibers. Tensile, flexural and impact strength of the composite were determined to study the mechanical properties. The results showed the improvement in mechanical properties of surface treated WSM E-glass fiber reinforced with epoxy polymer matrix composites. The heat treated WSM E-Glass Fibers coated with Ethyl silicate showed the excellent improvement in mechanical properties. Experimental results of mechanical properties for different surface treatment of E-glass fiber were evaluated and compared to conclude.

The weight reduction with enhanced strength is the primary requirement of Automobile Engineering field. Fiber which serves as a reinforcement in reinforced plastics may be synthetic or natural past studies show that only artificial fibers such as glass, carbon etc., have been used in fiber reinforced plastics. Nowadays silencer covers are making from conventional materials like stainless steel. Disadvantages of using conventional materials are more weight and higher manufacturing cost. Instead of going for conventional material the present study is reduce the weight of the product and minimize the cost. The significant technical advance is to identify the new composite material, which consists of glass fiber/modified epoxy laminates with inclusion of nano fillers .This material will be used to fabricate new auto ancillary parts and its mechanical characteristics will be analyzed. Parts produced by these materials are obtained more strength and life time than the existing parts and which is helpful for human beings and environment.
Effect of Glass Fiber Surface Treatments on Mechanical Strength of Epoxy Based Composite Materials
Journal of Colloid and Interface Science, 2002
Sizing glass fibers with silane coupling agents enhances the adhesion and the durability of the fiber/polymer matrix interface in composite materials. There are several tests to determine the interfacial strength between a fiber and resin, but all of them present difficulties in interpreting the results and/or sample preparation. In this study, we observed the influence of different aminosilanes fiber coatings on the resistance of epoxy-based composite materials using a very easy fractographic test. In addition, we tried a new fluorescence method to get information on a molecular level precisely at the interface. Strength was taken into account from two standpoints: (i) mechanical strength and (ii) the resistance to hydrolysis of the interface in oriented glass-reinforced epoxy-based composites. Three silanes: γ -aminopropyltriethoxysilane, γ -Aminopropylmethyldiethoxysilane, and γ -Aminopropyldimethylethoxysilane were used to obtain different molecular structures at the interface. It was concluded that: (i) the more accessible amine groups are, the higher the interface rigidity is; (ii) an interpenetrating network mechanism seems to be the most important for adhesion and therefore to the interfacial strength; and (iii) the higher the degree of crosslinking in the silane coupling layer is, the higher the hydrolytic damage rate is.
