Effect of NaOH concentration and immersion time on the mechanical properties of coconut coir–sugar palm hybrid composites

Natural fiber–reinforced composites are increasingly developed as sustainable alternatives to synthetic materials, but their performance depends strongly on fiber–matrix interfacial bonding. Alkali treatment can improve this bonding by removing hemicellulose, lignin, and surface impurities; however, the joint optimisat...
