Abstract
A nanostructured hierarchical coating inspired by the structure of the natural nacre was developed on individual fibres of an AS4 12k carbon fibre tow. A simple layer-by-layer (LbL) deposition method was adopted to coat layered double hydroxide (LDH) nanoparticles to mimic a brick-and-mortar-like architecture found in natural nacre. LDH particles of suitable size and surface charge were synthesized and characterized using X-ray diffraction, dynamic light scattering, and transmission electron microscopy. The quality of the nanoparticles was initially observed using a monolayer of LDH particles coated on a glass slide. This coating displayed a homogeneous monolayer of LDH particles with no significant particle agglomeration and uncoated spots. Following the same coating protocol, 15 layers of LDH particles were coated using LbL deposition on a surface-treated unsized AS4 12k carbon fibre tow and characterized using scanning electron microscopy. The initial findings indicate the formation of a well-structured LDH multi-layer coating. The main objective of preparing such coated fibres is to inhibit or delay micro buckling under compression when used as reinforcement in a polymer composite. In forthcoming studies, these coated fibre tows will be transformed into unidirectional epoxy-matrix
composite rods and subjected to compression testing.
