Over the last few years, there has been an increase in the use of fiber-reinforced composite (FRC) materials in many areas, mainly due to the superior high-strength properties of these materials and their low weight and corrosion resistance. Among them, glass fiber reinforced composite get popularity due to its inexpensive cost over carbon fiber, stiff, strong, durable, easy to repair, and simple to form. This book, therefore, presents an experimental investigation of buckling load of plywood plates reinforced with glass fiber/epoxy prepreg with various thicknesses. Especially, the buckling load of a plywood plate reinforced with glass fiber prepreg plywood at the lower or upper facing is estimated with various reinforced fiber prepreg thicknesses and compared with the buckling load of unreinforced plywood. Plywood laminated with FRC fabrics provide a superior composite which is light and has significantly improving buckling load characteristics compared to untreated plywood material. This analysis must have shed light on research area which is glass fiber prepreg/epoxy reinforced plywood part, be useful to anyone and professionals who interested in reinforcement, and buckling load
