Abstract:
The
first part of this study talks about the general properties of composite
materials and their application areas. Then, it explains manufacturing methods
of composite materials, compares these methods, and discusses which method is
more efficient for a specific application.
The
steps, the advantages and the disadvantages of the main composite fabrication
methods including hand-lay-up process, spray-up, filament winding, compression
molding, resin transfer molding, injection molding process, autoclave process,
pultruzyon, pulforming, sheet molding compound and bulk molding compound are
explained. The properties of the fibers that were used, resin types, molds, and
equipment are discussed along with the produced samples.
In
the experimental section, a support element that has been fabricated using the
autoclave/vacuum bagging method, was tested for stress-strain behavior under
different load amounts by fixing one end of the sample. The experiments
included bending and torsion tests.
Finally, the data were modeled in ANSYS by
defining the boundary conditions and the applied loads. The strain and the
torsion behavior were analyzed using the modeled data. The experiments were
repeated after modifying the model and the results were compared.
