Abstract
Resumo This work presents the function of biobased (palm fiber) as reinforcement in brake pad materials. Reinforcement in brake lining improvise wear stability, wear resistance and friction optimization under a dynamic set of operating variables such as braking force, sliding speed, braking duration and braking temperature. Palm fiber have an attractive performance to cost ratio and have stimulated the idea of exploring their possible incorporation into brake pad composite materials. The effect of palm fiber loading on physical, mechanical and tribological properties of composite brake pad is evaluated. The palm fiber is loaded with 2%, 4%, 6%, 8%, 10% and 12% as an alternate of rockwool fiber by varying the pressure and speed in a pin on disc tribometer.By increasing the pressure, 8% and 10% show high friction stability at all speeds. The results show that by raising in the palm fiber quantity the hardness, specific gravity and heat swell increases, and also the loss on ignition and porosity decreases. The SEM descriptions of the composite indicated that the smallest micro voids occurred in the sample having low palm fiber. Finally, the effect of surroundings on the composites was investigated in salt water, water and oil. Palavras-chave: Palm Fiber, Wear, Friction Stability, Brakes, SEM
Highlights
The Intelligent product systems (IPS) suggests that commodities of service consist of substances that can be endlessly reused in technical cycles and commodities of consumption consist of substances that can be securely introduced into biological cycles [1,2]
The physical and mechanical properties of palm fiber loaded friction composite are presented in figure 2
In 2PF loss of ignition (LoI) is high which indicates the pyroprocessing of friction material was incomplete
Summary
The Intelligent product systems (IPS) suggests that commodities of service consist of substances that can be endlessly reused in technical cycles and commodities of consumption consist of substances that can be securely introduced into biological cycles [1,2]. A brake system must provide steep and stable friction, vibration free performance, low wear and noise. These properties can be obtained by using more than 10 ingredients in a single brake pad. Palm fiber is enriched with Potassium, Selenium, Silica, Copper, Iron, Sodium, Calcium and Manganese like asbestos [23,24,25] It is a viable alternate for asbestos in friction material. Thermal stability and dielectric constant of the composite materials can be augmented It is the muse behind this work to examine the impact of palm fiber on the frictional properties. This work provides substantial evidence to use bio-based composites in brake pads
