In order to properly form the carbon composite shape,
it was deemed necessary that a formwork be created.
This formwork was constructed of 1/4" plexi-glass, and
was shaped using a rigged "heat-brake." (Shown)















The plexi-glass was held in place and heated regularly
across a concentrated axis until flexibility was achieved. (Shown)



















Below: The Carbon Fiber primary structural element.
The initial layer was a bi-directional weaving, however the
central-most layers were "uni-directional." The uni-directional
carbon fiber mat resin impregnation is a noticeable challenge
when compared to the bi-directional surface mat.















A second layup, on a second plexi-glass form was also
deemed necessary. (Below)










As the resin heat-cures itself, pushing, pulling,
expansion, and contraction were to take place. This
caused a considerable amount of damage to the plexi
form. It was decided that a better approach would
be to allow initial layers to cool and cure, as they
would be able to absorb many of the inherent stresses.
(Below)



















Machining and shaping of cured items was made possible by
using a metal blade (containing carbon fiber itself) within a standard
table saw. Cutting of the material, which is structurally stronger and
lighter than steel, was interestingly much more easy to cut, and
more forgiving to work with, when compared to steel or aluminum.















These are just a few of the related exercises and issues related
to the inherent processes of carbon fiber composite materials.
