Abstract

We describe how the mechanical properties of natural fibre composites can be improved by precipitating coral-like coatings to the surfaces of reinforcing fibres. We consider three amino-acid templates (L-lysine, glycine and β-alanine) on calcium carbonate growth to natural fibres. L-Lysine forms reticulate flower-like crystals,
-alanine forms globular crystals and glycine forms blocky crystals. These coralised fibres are used to reinforce styrene butadiene rubber and when compared against untreated-fibre reinforced composites; we find that at sufficiently high concentrations L-lysine templated mineral coatings improve composite strength by more than 100%. Contrarily, β-alanine and glycine templated mineral coatings do not improve the composite strength by more than ca. 60% and ca. 40% respectively. Molecular dynamics simulations elucidate the attachment mechanisms for each amino acid and the highest potential is in the l-lysine templated crystals. Finite element analyses reveal the success of l-lysine templated coatings is due to a heightened fibre tractive resistance.
