Abstract - The main purpose of the project is to utilize the
embedded in the matrix) and as layers (fibers woven into mats which are laid on top of one another to create a laminate) The reinforcing materials provide increased strength and stiffness to the composite. The matrix materials, on the 4 other hand, are responsible not only for covering the reinforcements (thereby protecting them from environmental and chemical damage).
waste Glass fiber reinforced plastic (GFRP) for different applications under mechanical recycling process. Fiber reinforced polymer (FRP) materials are being increasingly used in several applications, but especially in the construction and transportation industries. The waste management of FRP materials made with thermosetting resins is a critical issue for the composites industry because these materials cannot be reprocessed. Therefore, most thermosetting FRP waste is presently sent to landfill, in spite of the significant environmental impact caused by disposing of it in this way. Because more and more waste is being produced throughout the life cycle of FRPs, innovative solutions are needed to manage it. In this work a new composite material was studied and tested based on fiberglass waste mixed with polyester resin in different ratios of GFRP fiber waste and polyester resin at 65%, 70%, 75%. The newly fabricated composites were characterized for their mechanical properties such as compressive strength, Flexural strength, Hardness, Impact strength and Water absorption as per ASTM standards. The results demonstrate the possibility of using an unexplored waste stream (glass fiber waste) as a reinforcement agent in resin, which may reduce the amount of wastes in landfill, while simultaneously contributing towards the circular economy.
In this work, glass fiber reinforcement in polyester resin matrix was produced by hand lay-up technique with varying fiber percentages (15%, 30%, 45%, and 60% by weight percent). The compression, flexure, impact and hardness tests were carried out and their performances were evaluated. 1.2 POLYMERS AND FIBERS Commercial plastics are known as resins and are made of polymers. These polymers have been compounded with modifying or stabilizing additives. Typically based on the element carbon, polymer molecules are made from simple, oil-based raw materials. The starting materials for polymers are called monomers and they are small molecules. These small molecules go through a process called polymerization which combines them and forms very large molecules or polymers.
Key Words: Glass fiber reinforced plastic (GFRP), Mechanical properties, waste management, Thermosetting resins, Circular economy.
Fibers are the load-carrying elements and provide strength and rigidity, while the polymer matrices maintain the fibers alignment (position and orientation) and protect them against the environment and possible damage.
1. INTRODUCTION Composite materials can be formed by combining two or more materials with different properties together at macroscopic level to get enhanced properties as a combined effect. Composite materials are consists of two phases: the matrix phase & reinforcing phase. Epoxy resins, which are thermoset material are widely used as matrix in many fiber reinforced composites; particular interest to structural engineers owing to the fact that they provide a unique balance of chemical and mechanical properties combined with wide processing versatility.
2. MATERIALS AND METHOD 2.1 RESIN The unsaturated polyester resin (Medium Reactive General Purpose Lamination Grade Resin) of the grade VBR2303. The ortho lamination resin properties are listed in table 1. Cobalt naphathanate as accelerator and methyl ethyl ketone peroxide (MEKP) as catalyst were used.
1.1 TYPES OF COMPOSITE There are three principal ways in which the reinforcing material can be incorporated: as grainy material (or particulates), as fiber (in the form of individual fiber © 2021, IRJET
