Tensile, Flexural and Impact Properties of Luffa Cylindrica and Pineapple Reinforced Polymer Matrix hybrid Composite

Abstract

Composites are emerging as realistic substitutes to the metal alloys in many applications like automobiles, marine, aerospace applications, sports goods, etc. Fiber composites offer many benefits such as low specific gravity, tensile strength and modulus, comprehensive strength, better fatigue strength, etc. Owing to the low specific gravity, the
strength weight ratio and modulus weight ratio of these composite materials are markedly superior to those of metallic materials. Composites also afford design flexibility because many of them can be made into different compound shapes. The problem is probably the cost may higher for synthetic fiber also it will not be easily available in the mean time of the fabrication. Even though the resulting product is more efficient, and eco-friendly in working environment the raw materials are often costly. In this paper, we started with natural fiber and a natural resin. Due to some bonding difficulties with fiber and its properties we started our work with Luffa Cylindrica and pine apple fiber which is naturally available in native regions and also at low cost. General-purpose polyester resin is used as the bonding matrix.
In this research paper we intended to carry out basic mechanical testing’s like tensile, flexural and impact to identify the behavior of this type of hybrid materials and also its real time applications which satisfy some of our day-to-day usage of products or to make a new application in different fields.
