Pressure and temperature sensitivity analysis of palm fiber as a biobased reinforcement material in brake pad

Abstract

The effect of palm fiber on properties of automotive brake composite materials is analyzed. The test procedure followed is JASO C 406, which is for passenger car pads. Tribological properties of three brake pads (6 PF, 8 PF and 10 PF) were tested on full-scale inertia dynamometer for various performance parameters such as pressure-speed sensitivity (effectiveness studies) and Temperature sensitivity (fade and recovery behaviour). A pad undergoes all the testing parameters and maintains its low temperature rise in the disc for three pressure sensitivity and two temperature sensitivity tests. By increasing palm fiber content, hardness, heat swell and specific gravity increases, and also porosity and loss on ignition decreases. Test has been conducted using scanning electron microscope to analyse the all three specimens to evaluate the contact plateaus and wear debris during braking. 8% of palm fiber content in brake pad was found to be superior to 6 PF and 10 PF in most of the important tribological properties.

Effect of TiO2 nano-filler in mechanical and free vibration damping behavior of hybrid natural fiber composites

“…Natural fiber reinforcements with various matrices are studied in researches, in that about 15-20% are used for the application of automobile field, and more than 50% for the construction applications. Other applications are in the field of tiles, furniture and industrial applications [3][4][5][6].…”

Ecological Transition in the Field of Brake Pad Manufacturing: An Overview of the Potential Green Constituents

“…Berdard et al ( 2018) investigated the impact of palm fiber on the tribological performance of composite materials. It was found that an increase in palm fiber content led to high hardness and 8% of palm fiber content in friction materials resulted in good tribological performances [145]. Different composites including palm kernel fibers as reinforcement resulted in a hardness decrease with increasing palm fiber content as a consequence of the porosity induced in the composites.…”

Effect of intralaminar hybridization on mode I fracture toughness of natural fiber-reinforced composites

“…An added advantage of vegetal fibers is that in some applications, they can be an alternative in replacing synthetic fibers such as glass fiber [4][5][6]. Some applications of natural fiber-reinforced composites (NFRCs) in industry are construction and furniture, music instruments, protective materials (shin guards and helmets) in the sports industry and secondary structures (such as door panels, dash boards, headliners and seat backs) in the automotive industry [2,[7][8][9][10][11][12]. However, the applications of NFRCs are still limited to nonstructural parts because of a number of disadvantages, such as variation in their mechanical properties, fiber-matrix adhesion (hydrophilic characteristics of the vegetal fibers) and low moisture resistance [13].…”
