Abstract

The knowledge about manufacturing and the resulting mechanical properties using fibro-reinforced material is currently limited in Colombia. This preliminary study using beams made of fiber reinforced material was undertaken to evaluate the elastic modulus of the composite material, which will be subsequently used to design an external fixation system for bone transportation. Specimens were made of carbon fiber fabric using epoxy resin as the matrix. A hand lay-up manufacturing process varying number of carbon fiber layers was implemented to evaluate different fiber volumetric ratios. The elastic modulus was experimentally obtained by performing bending tests based on the ASTM D7264 standard. Also, the elastic modulus was theoretically calculated using the rule of mixtures. The experimental and theoretical elastic modulus was lineally increased for increasing the volumetric fiber ratio. However, the experimental results were considerably smaller than the theoretically obtained results, which might be produced by a possible presence of wrinkles or misalignment of the fabric produced during the handling inside the mold. It could be also produced by incomplete adhesion between the fiber and the resin.
