Eco-friendly treatment and coating for improving the performance of sisal composites

This is the first investigation aimed to enhance the mechanical, thermal and viscoelastic properties of epoxy based sisal composites using eco-friendly treatment (i.e. NaHCO3 treatment) followed by eco-friendly polymer coating (i.e. PLA coating). The composites were fabricated by manual method with...
