Alumina–Silica Hybrid Reinforcement in Jute/Epoxy Composites: Mechanical Characterization and Modified Rule of Mixtures for Strength–Toughness–Hardness Optimization

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Natural fiber composites offer sustainable alternatives to synthetic materials but need performance enhancement for structural applications. This study investigates the mechanical behavior of jute fiber–reinforced epoxy composites modified with alumina–silica hybrid fillers at varying compositions and loadings.

Flexural tensile behaviour of enhanced performance concrete

, 2004
High-performance concrete is generally produced using carefully selected high quality materials. These materials increase significantly the initial costs, hence, limiting its use. In this research work the performance of concrete was enhanced through incorporating low cost untreated materials like fly ash and crushed aggregates.
