Tribological Properties of Epoxy/Aramid Fabric Composites Reinforced by Boron Nitride of Single Layer

Abstract

Epoxy composite coatings filled with boron nitride of single layer (SBN) were prepared through a dip-coating method. The friction and wear behaviors of the coatings were performed, and the results showed that the wear life of composite coatings was obviously higher than that of pristine coating with low SBN content; however, friction coefficients only decreased slightly. The optimal content of SBN was 3 wt.%, and the wear life of the composite coating increased by 179% compared with that of pristine coating. The morphology of worn surfaces was studied, and the wear mechanisms were discussed.

Study on Tribological Properties of Carbon/Aramid Fabric Coatings Modified by Boron Nitride of Single Layer

“…First, boron nitride of single layer (SBN) was prepared by the method described in reference [5] . The simple procedures are as follows.…”

“…Boron nitride of single layer (SBN) has been investigated as another 2-D atomic crystal recently [5,26] , and is among the most promising inorganic nanofillers so far. It is expected that boron nitride of single layer would keep pace with graphene and could play a key role in the field of polymer nanocomposites.…”

“…As individual atomic sheets from bulk crystals, 2-D atomic crystals are well known for their good properties such as very high mechanical strength and heat resistance, and they have been regarded as the most promising nanoscale materials [5,15] . Graphene, which is a typical representative of the 2-D atomic crystals, has been researched extensively in many fields of the composites.…”

“…In the past decades, many kinds of fabric-based polymer composites have been well studied, such as glass fabric (GF) [6] , carbon fabric (CF) [7] , polyester fabric [8] , aramid fabric (AF) [5] , etc. Among these fabrics, CF is recognized as a promising reinforcing element especially for reinforced plastics in aircraft construction because of its high strength (∼4.5 GPa), high modulus (∼380 GPa), and good thermal conductivity, all of which are of advantage for tribological usage.…”

“…In addition, epoxies are one of the most favored polymer matrices for developing highperformance composites, especially for aviation and aerospace fields [1][2][3][4][5] .…”
