In this research hemp fibers have been modified by the sol-gel method in different combinations to implement silica nanolevel coating on fiber surface without compromising the mechanical properties of the fibers and ensure sustainable coverage to achive matrix-filler compatibility in composite as filler. The coatings of samples prepared using different proportions of nano-sols of samples was made. The fibers were immersed in the prepared sols made from ethanol, tetraetoxysilane (TEOS), distilled water and hydrofluoric (HF) acid. Scanning electron microscopy (SEM) has been used to examine the nature of the surface modification. Energy dispersive X-ray (EDX) analysis used for the analysis of chemical compositions on modified fibers surface. Analyses based on the SEM show that small sol components proportion differences significantly affect coating resistance.
