If I was to create a shape in CF using EF80 Flexible Epoxy Resin, once the bent shape is in position can I then reinforce it to a stiff strong form using your regular epoxy resin and reinforcement layers of CF over the EF80 Flexible Epoxy Resin?

Epoxies once fully cured are thermoset plastics so cannot be heated and reshaped. They will, however, go soft and distort when initially brough into contact with heat while the parts are fresh.  This is because at room temperature not all the molecules have cured hence the first initial increase in temperature can soften the resin while the final curing takes place. This softening does not mean you can reshape it though as it would distort and the smooth surface finish would likely be lost with "print through" of the carbon fabric onto the surface.
