A Study Based on the Use of Textiles from Worn Tires in Manufacturing FRP Composites and Decreasing Adverse Environmental Effects

Retrofitting structures is one of the most important discusses in the construction industry. Nowadays,by using various FRP composites due to the potential plasticity, light weight and high tensile feature, we can reduce weaknesses of concrete structures and increase the resistance of structures. Composites are suitable successor for traditional amplifiers such as the use and installation of steel pages in weakness locations of structure and further concreting. Composites are composed of carbon fiber textiles or glass which are mixed with epoxy resin adhesive mortar and create mix that by placing on the surface of weak part of the structures can result in increase of structural strength against tensile forces. Fiber parts of the composites withstand tensile forces and must have sufficient strength against changes in temperature and humidity. Fibers form a significant part of car tiers (about 30%) and have duty to maintain and equip the tires rubber particles. In tire recycling process, rubbers are shredded and become rubber powder. The result of this process is separation of fibers which are 30% of total materials that formed tires. These textiles are considered as waste materials in recycling centers and are one of the challenges in waste management and considerable costs are spent to land filling them annually. Land filling of these textiles can cause soil and groundwater contamination and produce dangerous gases which are harmful for environment. Because of excellent resistance of these textiles, by using them we can produce composites which have considerable plasticity ability and high resistance against tensional forces and changes in temperature and humidity. In this article, the use of worn tires textiles in composite manufacturing, increasing the quality of composite and reducing severe environmental effects are investigated.
