As a result of the depletion of natural raw materials, the study focused on finding alternatives, such as making use of industrial waste, incorporating it into composite materials, and analyzing mechanical properties through a variety of tests such as fatigue, comparator, swelling, and aging test. Wasted fiber and crumbed rubber extracted from the recycling of tires in the Al-Diwaniyah tires factory, was added with different concentrations depending on the weight of the reinforcement agent. The results were discussed and compared with the standard recipe that used black carbon, where the results showed an improvement Notable in some of the characteristics of the recipes. The results of mechanical tests (fatigue, aging, swelling, compression) were compared with the standard recipe, a clear improvement was observed in the properties, as it was found that the recipes reinforced with wasted fibers increase the resistance to fatigue failure in concentrations (1,2,3,5) %, to record the longest shelf life (8703) cycle at concentration (5) %, compared with the standard prescription that recorded (8235) cycle, and fails in the other concentrations. While the recipes were reinforced with crumbed rubber, the longest life (9971) cycle was recorded at concentration (3) %, after which it begins to decline. As the swelling test showed, the recipes reinforced with wasted fiber showed an increase in the concentrations (1,2,3,5,10) %, and a decrease in the values of the swelling for the concentrations (15,20,25) %, but the recipes reinforced with crumbed rubber, showed an increase in swelling with the increase of waste amount in all recipes. The study showed that increasing the loading, whether with wasted fibers or crumbed rubber and in certain amounts, the better it was in withstanding and gave acceptable results. All these characteristics combined, give us a clear vision of how to exploit industrial waste in engineering applications with more benefits. [ABSTRACT FROM AUTHOR]

The difficulty of biodegradation of rubber is an important motive for how to make the most of it, so the current work came to develop recipes of rubber composite materials reinforced with industrial waste, and conduct laboratory tests such as abrasion and hardness tests. Two types of industrial waste were used in the preparation of recipes (wasted fiber and crumbed rubber) from the tire recycling process in Al-Dewaniyah Tires factory and these materials were added in different load percentages (1%, 2%, 3%, 5%, 10%, 15%, 20%, and 25%) and all these recipes were discussed with a standard recipe that used carbon black only as a reinforcement agent. The results showed the mechanical properties were improved in some of these recipes. Firstly, the abrasion test results showed imperceptible improvement in this property and then increase with increasing load percentage till 10% of wasted fiber load percent while the acceptable results were till 5% percent of crumbed rubber with value about 4.95% and 7.62% respectively compared with 7.82% for a standard recipe. After these load percent, the property deteriorated. Also, the results showed improving the hardness of recipes with increasing the load percentage for two types of waste material and the load percent 3% may be an acceptable value with 61 IRHD and 60.5 IRHD for wasted fiber and crumbed rubber respectively, was that compatible with some engineering applications. All these results may reflect the ability to use these materials as a reinforcement agent with several benefits such as economic and environmental benefits. [ABSTRACT FROM AUTHOR]

The world is exposed to serious environmental problems as a result of the rapid development of modern technology, which is the increasing rate of tire consumption, the difficulty of its biological decomposition and its accumulation that causes serious fires and the emission of toxic gases harmful to nature and living organisms, The tires act as a basin to collect water, which forms hotbeds for the growth of bacteria and parasites. Therefore, the study focused on finding solutions for how to benefit from and recycle used tires. The (wasted fibers, and crumbed rubber) resulting from recycling were mixed with the composite materials in Al-Diwaniyah Tires Factory, and the mechanical properties (tensile strength, scorch time, cure time, and resilience) were studied in the Babylon Tires Factory. The results were compared with the standard recipe and it was noted that the addition of (fiber scrap, and rubber crumb) at certain percentages (3,5,10) and (3,5) % respectively gave high-performance properties compared to the standard recipe in the majority of the tests that were made. The study showed the economic and environmental benefits of recycling scrap tires and the possibility of exploiting them in many engineering applications as a successful path toward sustainable environmental development.
