Abstract

Over the last few years, there has been an increased usage of fibre-reinforced composite (FRC) materials in structural applications, including rehabilitation and retrofitting, mainly due to superior properties such as high strength, low weight and corrosion resistance of FRC materials. These superior properties of FRCs can be exploited in applications where simple light weight construction is a priority. Plywood is one of the most widely used materials in a number of light weight applications in the construction industry. This paper presents an experimental investigation of buckling behaviour of plywood plates reinforced with advanced fibre composite materials. Plywood laminated with FRC fabrics provide a superior composite which is light and has significantly improved buckling (stability) characteristics compared to its parent plywood material. The lateral deflections corresponding to increasing in-plane compressive loads on reinforced plates were closely monitored and compared with those plates with no reinforcement. 4.5mm thick plywood laminated with three different composite fibres (namely, carbon, aramid and glass) were considered in the investigation. The results of the study indicate that FRC-reinforced plywood plates exhibit a significant reduction in deflections and increase in the load carrying capacity in buckling applications.
