Buckling of Symmetric Laminated Fiberglass Reinforced (FRP) Plates

by Austin, Calvin Deon

Abstract (Summary)
Fiberglass reinforced plastic (FRP) is a composite material made of fiber reinforcement surrounded by a solid matrix. FRP is slowly making its way into civil engineering structures. The many advantages of FRP, such as light weight, corrosion resistance, and the ability to vary its properties over a wide range of values, have made it a competitor to steel, concrete and wood as a building material. Although FRP has existed for many years, there is still much about it that needs to be understood before it is to be accepted as a building material in civil engineering structures. The objective of the current work is to investigate the buckling of FRP laminated plates. The buckling load of an FRP laminated plate depends on a variety of variables, including aspect ratio, thickness of the laminate, fiber orientation of the laminae that make up the laminate, and the boundary condition. These variables were related to the buckling load of laminated plates by analyzing a number of laminated plates using the commercially available ANSYS finite element software. Among other things, it was found that for the analyzed FRP laminated plates simply supported on all edges the optimal fiber orientation of the mat layers was + 45 degrees, but that was not the case for the other boundary conditions.
