Influences of fiber fibrillation degree on mechanical and tribological performances of aramid fiber/nitrile rubber composites

Abstract

Three types of aramid fibers (AFs) with various surface fibrillation degrees were introduced into nitrile rubber (NBR) matrix to prepare the AF/NBR composites, respectively. Their impacts on the mechanical and tribological performances of the NBR composites were mainly studied. The results showed that, as the fiber content increased, the tensile strength of the AF/NBR composites increased after initially decreased, and the turning point moved toward the direction of lower AF content with the fiber fibrillation degree increase.

“…When used as a reinforcement in composites, AP has great advantage of connecting with the matrix due to the large surface area. [13][14][15] However, the high fibrillation of the AP causes problems, especially tangling between the fibrils, which leads to fiber aggregation in the matrix. This issue negatively impacts the uniformity of the composites, and decreases the mechanical properties.…”
