Potentiality of Luffa Fiber Used as Reinforcement in Polymer Composites,ndustrial, and other commercial markets. In the present study, various chemical treatments of native luffa fiber (. surfaces using alkalization (2 h agitation with 5 % KOH) and furfurylation (graft furfuryl alcohol followed by oxidation with K.Cr.O. (1N) is discussed and compared. The purpose of che

Mechanical Properties of Natural Fiber/Synthetic Fiber Reinforced Polymer Hybrid Composites,is the use of natural fiber/synthetic fiber combination in polymer hybrid composites. Although the biodegradability of the composites is compromised by synthetic fibers, this is compensated by the improvement in their mechanical and physical properties. Hybrid composites use more than one kind of fi
