Effect of Grafting Silane coupling agent on the glass fibers /epoxycomposite

Silanization treatment of fibers is one of the suggested methods to improve adhesion between thefibers and matrix . This study is conducted on silanization of glass fibers. To do so, the activatedglass fibers by acid etching were silanized using a solvent and ɤ -amino propyl triethoxy silane as asilane agent. The Attenuated Total Reflectance -Fourier Transform Infrared Spectroscopy (ATRFTIR)analysis confirms the successful silanization process. A pull-off test was carried out on thetreaed glassfiber/epoxy composite which showed an increase in mechanical strength of the glassfiber/resin composites, suggesting strengthened adhesion between the treated glass fibers and epoxyresin within the composite material
