The bi-directional jute fiber reinforced epoxy were subjected to mechanical characterization. Its mechanical properties were analyzed. The results revealed that the jute epoxy composite exhibited good mechanical properties.
A. Density And Void Fraction
One of the main factors that determine the properties of the composite is density. It is often found that the theoretical values of density will not match with the experimentally measured values. This is primarily due to the presence of air bubbles or also known as voids in the composite .This has a considerable contribution to influence the mechanical properties and the performance of the composite in the actual workplace. Elevated void contents usually mean lower …show more content…
The Charpy impact test, also known as the Charpy V-notch test, is a high strain-rate test which determines the amount of energy absorbed by a material during fracture. The Charpy test specimens were made according to the dimensions of standard ASTM A370. One of the main reasons for concern for natural composites laminates generally is the low values of impact energy. These laminates show relatively low values of impact energy compared to metals. The ways to increase the impact energy of the composites laminates are being made the major area of research. The impact test was carried out by Charpy test and the results were recorded are shown in Table III. The fiber provides strength for the composite material, as the jute fiber percentage in the composite is only 42 percentage, the jute reinforced composites seems to have fair impact strength. The reason being jute fiber contains higher cellulose content and lower micro fibril angle results in higher work of fracture in impact …show more content…
This study examined the physical properties of epoxy composites reinforced by bi-directional jute fibers which can act as better reinforcement. It was found that jute/epoxy composites have mechanical properties of sufficient magnitude to compete with conventional synthetic composites. The use of untreated fiber and epoxy with mould have yielded very good mechanical properties which are proved from the experimental results. The mechanical properties of the bi-directional jute reinforced epoxy composites have given enough confidence to manufacture light weight and fairly satisfying strength parts for house hold applications like window frames, doors etc and automobile parts. But the actual weathering conditions on the laminate need to be studied thoroughly to use them in the respective applications. This study is expected to provide more comprehensive insight into biodegradable green
