Polymer Composites Based on Aromatic Polyamide and Aramid Fiber for Heavy-Duty Friction and Sealing Units
The paper substantiates the selection of a polymer and filler based on aromatic polyamide to create a material of friction pairs that operate in heavy-duty friction and sealing units of up-to-date vehicles and machinery. The effect of load and sliding speed on the tribological behavior of the initial aromatic polyamide and filled 15%-aramid fiber was studied. As a result of tribological studies, the terminal operating conditions of products made of initial aromatic polyamide and a composite based thereon, filled with aramid fiber, have been determined.
