Abstract
Carpets are the three-dimensional product used as a floor covering in homes, offices, commercial centers, decorative purposes, etc. The average life span of the carpet is four to seven years and after that, it becomes solid waste. The discarded carpets are causing a significant hazardous effect on the environment, climate, soil, and various health issues. To overcome the increasing carpet waste, the re-utilization of carpet is essentially desired. This article focuses on the development of polymer composites developed from discarded nylon carpets for lightweight applications. A modified technique of Vacuum-assisted resin transfer molding (VARTM) was used to fabricate epoxy composites. The tensile and flexural tests evaluated the mechanical performance of the proposed composite. The modified composite is manufactured in two different configurations, namely, face- back-to-back-face (FBBF) and back- face to face- back (BFFB) with the help of the VARTM setup. The result demonstrated that the fabricated BFFB composite has a higher strength. The high-resolution microscopy test of the developed samples shows the feasibility of the composites produced from discarded carpet for lightweight functions. An attempt has been made to resue the waste for the fabrication of cost-effective products.
Highlights
Nowadays, carpet waste is a huge concern for the environment and the economy due to high disposal costs and environmental hazards
The researcher stated that Styrene-Butadiene Rubber (SBR) greatly improved the impact resistance & sound absorption by maintaining the sound and flexural properties of fabricated composites
This paper focuses on the recycling of nylon carpet waste for the manufacturing of polymer composite
Summary
Carpet waste is a huge concern for the environment and the economy due to high disposal costs and environmental hazards. A survey has been remarked that approximately 40,000 tons of carpet are discarded as landfills in the United Kingdom (UK) itself This solid waste becomes a global concern for the environment and economy. Muzzy et al [10] used economic techniques to recycle post carpet composites without separating backing fibers with face fibers. Pan et al [11] fabricated composites from the discarded nylon 6/nylon 6,6 carpets and studied the mechanical properties, acoustics testing, and water stability. They stated that compression-molded composites had a greater elastic modulus, impact resistance, flexural strength, and sound absorption by 124 %, 32 %, 59 %, and 40 %, respectively as compared to the Jute/PP composites. This work target to utilize the massive carpet waste generated from domestic and industries applications
