Effect of silane blend coating on interfacial bonding of glass fiber/epoxy micro-composites

Investigation on interfacial micromechanical properties of fiber composites is of fundamental importance in designing composite structures. In this work, the influence of fiber surface coating on the behavior of glass/epoxy micro-composites composed of single glass fibers embedded in epoxy micro-droplets has been studied. Glass fiber samples were coated with single and blended silanes (Tetraethoxysilane and 3-glycidoxypropyltrimethoxysilane) and fiber/matrix interfacial shear strength and friction strength were evaluated by microdroplet test. Microdroplet specimens exhibited different results of the interfacial strengths due to the glass fiber surface treatment. Interaction between glass fiber and silane coupling agent were also investigated by ATR-FTIR
