NOVEL SYSTEM, ENHANCING THE MECHANICAL PROPERTIES OF BANANA FIBER AND TAMARIND SHELL PARTICULATE

Abstract

7. ABSTRACT OF THE INVENTION The main objective and novelty of this study is to investigate and enhance the the effect of particulate addition on the mechanical and thermal properties of natural fiber polymer composites. In this project, tamarind shell powder is used as filler material for banana fiber reinforced polymer composites. Epoxy resin which is known for better adhesion is chosen as matrix. Composite specimens were prepared at various compositions in combination of bana fiber and tamarind shell particulates by the rule of mixture in 10%, 20%, 30and 40% and mechanical test were carried out and the readings were compared. Results showed that 40% fiber content showed maximum mechanical and then the value gets declined with addition of fiber further. This is due to accumulation of fiber at one place at more than 40% level which results in improper adhesion. SEM images were obtained at fractured areas of Tensile & Flexural test samples.

4. DESCRIPTION

From the researchers it is noted that, natural fiber/filler-reinforced polymer composites have
fascinated global curiosity in automotive, marine, structural, and biomedical applications. Natural fibers are proved to be the best substitutions of synthetic fibers. Natural fibers/fillers have essential benefits, such as relativejy low cost, low density, green, non-hazardous and biodegradable, The major role of the, reinforcing
material is to improve the mechanical properties of the composite material. Reinforcements for the
composites can be fibers and fillers or particles. Fibers are the most widely used reinforcement material. Massive research work has been carried out on natural fibers reinforced composites. Fillers are alternative type of strengthening materials spread in the matrix phase. These fillers tend to limit the movement of the
matrix phase in the vicinity of each particle, leading to an improvement in the mechanical strength of the composite material.

In this work, banana fiber was used as reinforcement and tamarind shell particulate was
used as filler material. Epoxy resin was used as matrix. Composites were fabricated using hand layup technique by the addition of fibers and matrix in 10,20,30 and 40 percentage. Composite specimen was tested for their mechanical properties and SEM image was taken. From the drawings it is clear that 40% fiber content showed better mechanical properties and later deteriorated.

Novelty:
• The fabrication of banana fiber and tamarind shell particulate composites
• Fabrication of composites based on rule of mixture
• Mechanical testing procedures

Advantages:
• The method of fabrication improves mechanical property
• Good alternate for synthetic materials.
• Biodegradable material.

5. CLAIMS
We claim,
1. The Novel System, method of enhancing the mechanical properties of banana fiber and tamarind
shell particulate composites consists of fabrication of materials
2. Mechanical testing consists of Tensile, flexural, and compression tests.
3. Composite strength is improved by using the addition of tamarind shell particulates as filler.
4. The fabrication of material by 40% by the combination of both banana fiber and tamarind shell particulates gave better strength.
