Title: Composite portable shelter system produced by vacuum bagging using recycled reinforcement and matrix materials

Abstract

Composite materials, which are increasingly used in many sectors, are one of the developing branches of materials science. Composite materials, which are preferred due to their properties such as light weight, high strength, resistance to outdoor conditions and long life, offer opportunities to meet the need for shelter, especially in the construction sector, thanks to their good heat and moisture resistance. In recent years, the development of production processes sensitive to the use of waste has been supported for a sustainable world. To realize sustainable composite material production, alternative raw materials are needed. In this project proposal, it was thought that instead of glass, carbon, aramid fibers that constitute the reinforcement elements of composite materials, denim fabric wastes, and recycled polyester could be used as resin. It is aimed to produce composite materials resistant to outdoor conditions for the portable shelter system, suitable for emergency installation, by using waste jeans fabrics formed in the denim factory and unsaturated polyester resins recycled from PET (Polyethylene terephthalate) wastes, to be used in natural disasters or in cases of forced migration. Waste denim fabrics and recycled polyester resin; will both meet the need for sustainable raw materials and reduce raw material costs in composite production. Optimum processes and ideal composite material designs will be created so that the composites produced with new sustainable materials that will replace the currently used materials can reach the required strength values. As a production method, in the light of literature review and industry experience; Vacuum bagging method will be used due to its high strength, low cost and ease of production. The mechanical and thermal properties of composite materials produced with different waste denim fabrics and different fiber sequences will be compared with the currently used composite materials (for example: glass fiber + unsaturated polyester) and composite materials with sufficient properties will be determined. In addition, environmental gains will be examined with the life cycle assessment to be made at the end of the study.
