Modeling and
Buckling Analysis of Polymeric Composite Columns |
This
research studied the buckling of composite columns made from
glass fiber reinforced unsaturated polyester. The composite
specimens were prepared by hand lay-up technique with different
fiber volume fraction Vf, aspect ratio and angle of fibers when
reinforced with coarse and fine woven fibers. Mathematical
models were done by using statistical analysis which show the
critical load of the composite column as a function of volume
fraction, fiber angle and aspect ratio. The results show that
the maximum value of the critical load can be observed at volume
fraction Vf =11%, aspect ratio L/T = (3.5) and fiber angle θ =
(0º/90º) for fine fiber was (500.72 N). Also its found the
maximum critical load for coarse fiber can be observed at Vf
=8%, L/T= (3.5) and θ = (0º/90º) was (400.4 N). |
