Abstract:
In the area of technological advancement, environmental awareness are always drawing the
attention of the scientists for eco-friendly and recyclable products. Different kinds of composite
materials are available in the world fabricated from different materials. Natural composite
fabricated from natural fiber are attracted the researchers because of their unique characteristics
like bio-degradable, availability, non-toxic nature etc. In this study, a new composite materials of
epoxy matrix reinforced with three different fillers (banana fiber, jute fiber and jute fabricate biodegradable
polythene) have been prepared by different method namely die molding process,
hand-lay method and vacuum infusion method. Different composite materials have been made
using different types of fiber size, fiber types using epoxy resin. Assessment has been made to
find out the different mechanical properties and comparison has been made accordingly to find
out the suitable method for the fabrication of the green composite materials.
A mathematical model has been developed for the prediction and optimization of composite
materials. The centre composite design protocol along with the response surface method has
been adopted for compression testing of composite materials. A quadratic model has been
proposed to predict the compressive load of the molded green composite materials within five
levels of the two process parameters. Statistical tools are used for best fitting of the developed
quadratic model and desirability analysis is coupled with it in order to find out the optimum
process condition for which maximum compressive load is achieved. FEM simulation has also
be made to predict the dynamic behavior of the fabricated composite and comparison has been
made accordingly. From the experimental analysis, it has been observed that most of the
conditions the fracture occurs at the middle position of the specimen and maximum tensile
strength of 34.61 MPa obtained from the specimen using double layer hand lay method whereas
specimen obtained from hand lay using small particle has the lowest tensile strength of 4.31 MPa
considering all the methodological approaches. In compression testing the fabricated green
composite cylinder can withstand maximum compressive load of 38KN.
