Multi-scale analysis of the interface structure and failure behaviors for n-SiO2@jute fiber/PP composites

To enhance the interface bonding performance between jute fibers (JFs) and polypropylene (PP), nano-SiO2 (n-SiO2) layers were coated on the carboxymethyl treated JFs (JFs-COOH). Molecular dynamics (MD) simulation, microscopic modelling and macroscopic tensile test were used to study the interface structure and failure behaviors of n-SiO2@JF/PP composites at multi-scale level. The results of MD simulation indicated that n-SiO2 layer including gel...
