Investigation of Co-Pyrolysis of Plastic and Cocos Nocifera
Authors:- S. Ajith kumar, Janobin S, Halin Heijal A, Bisel M

Abstract- Generally all over the world, the usage of fossil fuels in the day to day life as liquid, gas and the solid have been highly increased. Nowadays the population is getting highly increased and at the same time, the usage of biomass is also increasing. Biomass is an alternate fuel from the starting era of biotic organism. The usage of plastic also increased. The disposal and recycling of plastic is facing a challenging task. The researchers are facing high tedious problem in destroying plastic. Since the decomposition of plastic is highly dangerous to the soil. Pyrolysis process is the most promising for the waste to useful form of energy conversion techniques. While destroying biomass and plastic, more carbon footprints are seen. End product of plastic and biomass pyrolysis has its own deficiency in its characterization. In order to overcome these drawbacks, biomass and plastic is combined together as mass quantity and undergoes pyrolysis process for finding the better result. The pyrolysis end product properties like ash content, moisture content, kinematic viscosity, density, flash point, fire point, cloud point, pour point, gross calorific value and specific gravity are determined.

Dynamic Mechanical Analysis of Discarded Polyurethane with Polyester Hybrid Composites

Dynamic Mechanical Analysis of Discarded Polyurethane with Polyester Hybrid Composites
Authors:- E. Bravin Daniel, Ajin B S, Ajun Jijo S, Berin J

Abstract- A composite material is a combination of two materials with different physical and chemical properties. When they are combined they create a material which is specialised to do a certain job, for instance to become stronger, lighter or resistant to electricity. They can also improve strength and stiffness. Polymer matrix composites (PMCs) are the most widely used composite type. Just as is the case for polymers, the environment typically needs to be controlled to obtain consistent test results for PMCs Polymer matrix composites (PMCs) have gained considerable interest mainly due to their low cost and higher specific strength and stiffness compared to conventional metallic alloys. This prepared composites were evaluated by dynamic mechanical analysis method such as dynamic mechanical analysis, X-Ray diffraction, Fourier transform infrared. The aim is to conduct the dynamic mechanical analysis of polyurethane and polyester composite. Polyurethane is the thermosetting polymer composite which can withstand high temperature. On the other hand polyester is the fiber material with ductile nature. After the preparation of the composites ,mechanical analysis of the specimen is to be analyzed.

Morphological Study of Discarded Polyurethane Hybrid Composites

Morphological Study of Discarded Polyurethane Hybrid Composites
Authors:- Mr. J. Starlin Deva Prince, Godfrey Mohan R, Milan Chand J S, Mohammed Shabeen J

Abstract- Hybrid materials are composites consisting of two constituents at the nanometer or molecular level. Commonly one of these compounds is inorganic and the other one organic in nature. Thus, they differ from traditional composites where the constituents are macroscopic. Mixing at the microscopic scale leads to a more homogeneous material that either shows characteristics in between the two original phases. Polyurethane is a plastic material, which exists in various forms. It can be tailored to be either rigid or flexible, and is the material of choice for a broad range of end-user applications such as: insulation of refrigerators and freezers, building insulation, High abrasion resistance Thick section molding , Colorability ,Oil resistance, Ozone resistance, Radiation resistance. Other advantages are castable nature and Low pressure tooling. This investigation helps to know about the morphological study of discarded polyurethane hybrid composite. Layout method is used for combining both polyurethane and nylon fibres. By using the following combination, we have prepared six samples with different samples as S1- S6. The percentage proportions as follows;
S1- 100% polyurethane
S2- 80% polyurethane + 20% nylon
S3- 60% polyurethane + 40% nylon S4-100% nylon
S5-80% nylon + 20% polyurethane S6-60% nylon + 40% polyurethane
