STUDY ON HYBIRD COMPOSITES REINFORCED WITH NANO-MATERIAL, NATURAL FIBRES AND BIO-MATERIAL

Abstract

In this thesis the Hybrid Composites reinforced with nano-material, natural fibres and bio-material are prepared as an alternate to the synthetic fibres, to provide sustainable and environmental friendly material which is better alternate to the existing composites. The Mechanical and Thermal properties are studied and results are consistent with the existing trends of the field. This study would help researchers to find new application of this environmental friendly material in various fields. The contents of the thesis are as follows: Chapter 1: This chapter illustrates the advantages of natural fibres filled composites over the synthetic fibres from various features. Types of fibres, their extraction and various treatment processes to enhance the reinforcement. The advantages of hybrid composites with nano-materials. Chapter 2: This chapter is on literature review of composites with various polymers as matrix and various filler as reinforcements. It reviewed various chemical treatment methods and grafting methods for better mixing and homogeneous material. The various methods and parameters for preparing hybrid composites are discussed. Advantages, limitations are compared for various processing methods. It also includes analysis of research gap, objective of research work. Chapter 3: This chapter discussed the various characterization techniques, including standards, details of equipments and conditions for studying the prepared Hybrid Composites for various Mechanical and Thermal properties. Chapter 4: This chapter deals with synthesis of the Hybrid Composites with details of the various constituents and details about the composition with varying percentage to prepare the samples of the specimens. It also includes the details of extrusion and injection moulding process and their parameters. Chapter 5: This chapter deals with the finding of results and discussions of the reinforced constituents to get the maximum values of Mechanical, Physical and Thermal properties of the prepared hybrid composites. Chapter 6: It summarizes present research investigation for the successfully prepared hybrid composites having comparable properties to synthetic composites, while having advantages such as the reduction of plastic waste and energy savings advantages of natural xiii fibres and bio-material. It also includes the future scope for further research in this field for new application of these composites.
