Summary:
This research studied the critical load of composite columns theoretical and numerical by using the ANSYS14 package depended on the experimental tensile properties of composite specimens. The composite specimens were prepared by hand lay-up technique made from unsaturated polyester reinforced with glass fibers with different fiber volume fraction Vf, aspect ratio (L/T), and angle of fibers for coarse and fine woven fibers. The critical load obtained by using the program (ANSYS 14) has also shown a good agreement with results that were obtained theoretically and the maximum difference was (0.7 %). The results show that the maximum value of the critical load can be observed at Vf = 11 %, L/T = (3.5), and θ = (0º/90º) for fine woven fibers was (622.115 N). Also, it found the maximum critical load for coarse woven fibers can be observed at Vf % = 8 %, L/T = (3.5), and θ = (0º/90º) was (486.887 N). Also, the observed values of tensile properties and predicated values are scattered close to the (45˚) line.
