Interfacial adhesion of natural fibres as reinforcement is the key parameter to be considered in fibre polymeric composites. In the current work, interfacial adhesion of date palm fibre is inverstigated using single fibre pull out experiments. The interfacial property of date pal fibre was determined with epoxy matrix. Scanning Electron Microscopy (SEM) was used to examine the surface morphology and damage feature on the fibre before and after the test. The influence NaOH treatment at different concentrations (0% - 9%) and embedded fibre length in the epoxy matric are considered. The results revealed that treated the fibre with 6% NaOH highly enhanced interfacial adhesion of the date palm fibre with epoxy matrix. The embedded length of the fibre controlled the interfacial adhesion property of the fibre where 15mm embedded length was the optimum fibre length. The lowest fibre critical length can be obtained at lower fibre diameter and 6% NaOH treatment
