The carbon fiber should provide the tensile strength and in should be thoroughly encapsulated in an epoxy resin matrix. With the expense of carbon fiber, it would be nuts to use a cheaper resin.
Where the sandwich could come in is to separate layers of carbon, such as with a foam or honeycomb, so that the high strength of the carbon 'skin' bears the load. Unidirectional layers, with maybe eight or more layers in crossing relationship and then compressed an the epoxy cured provide "quasi-isotropic" strength -- in all directions -- because the carbon itself is extremely strong in tensile strength ("pull") but weak in shear ("crosswise?").
Carbon fiber 'cloth' is actually much weaker (the fibers have bends, to make the 'weave') and is mostly used in the exterior-most layer for a better finish. When layed up void free, with enough crossing layers, it's stronger than steel.
