Fabrication of Wood‐Epoxy Composites via Integrated Brick‐Rebar‐Mortar Strategy Modulated to Achieve Near‐Zero Wear Period

ABSTRACT In order to extend the service life of mechanical components in harsh environments, it is essential to construct a good system with excellent compatibility and durability. Here, a wood‐epoxy composite with “brick‐rebar‐mortar” structure was designed to meet these challenges. The structure consists of hexagonal boron nitride (h‐BN) as the “brick”, epoxy resin (EP) as the “mortar” and lignocellulose as the “rebar”. In the whole system, lignocellulose not only acts as a dispersant to improve the nano‐aggregation of “bricks”, but also functions as a reinforcing agent to strengthen the bond between the “bricks” and “mortar”, forming a robust “interlocking” structure. The special structure gives films excellent friction properties, such as a near‐zero wear period and an ultra‐stable friction coefficient (0.08). This study provides a new reference for the fabrication of materials with excellent anti‐wear properties.
