Abstract
AbstractWHO and Environment protection agencies have reported that the trending brake pad materials are harmful to human health. These materials (Asbestos and Kevlar) produce toxic gases when used in brake pad composites. It is a cause of lung cancer, mesothelioma, affects the respiratory system, and causes many diseases. It has been causing many million people's death. Kevlar (aramid) is the trending material used in the brake pads. So, it is necessary to find a substitute for these toxic elements. In this direction synthetic fiber has been replaced by natural fiber. The main aim of this study is to find a substitute for asbestos and synthetic fibers (Kevlar) in brake friction material. There are very few comparative studies of Kevlar and natural fiber‐based reinforced polymer composites. In this research Abaca fiber and Kevlar fibers have been reinforced as brake friction material and compared studies. The brake pads were developed by using the various percentages of Abaca fibers (5–20%) and Kevlar fiber (5–10%) with other important ingredients of brake in the hydraulic hind Brake melding Machine. The results of physio‐mechanical properties reveal that % porosity, % water absorption, % compressibility increases as increase the percentage of Abaca fiber and Kevlar fiber in the polymer composite while ash, hardness, and density decrease with an increased percentage of Abaca and Kevlar fiber in the composite matrix. The tensile strength, ultimate compressive strength, impact energy, flexural strength, flexural modulus, tensile modulus shows the best performance for 5% brake pad composites among all Abaca fiber composites and while ultimate shear strength and proof stress show the best performance for 10% brake pad composites among all Abaca mixtures. The Abaca fiber composites with 5 wt% have shown improved results for the coefficient of friction, fade percentage and wear among all‐natural fiber composites while the performance in terms of recovery was observed to increase with an increased percentage of Abaca fiber. In the comparative study it has been found that Kevlar‐based brake pad specimens showed little better results in %‐fade, coefficient of friction, and in wear performance than that of Abaca‐composites while mechanical properties have shown nearby results. The wear rate and thermal stability were recorded highest for 20% Abaca fiber composite and 10% Kevlar composite.
