I'd recommend you replace the carbon with S2 glass or E-glass; however, your problem is easily fixed with the additional application of "extra heavy hold hair spray" (aerosol type) used in the mold. Hair spray cheap substitute for the traditional PVA mold release. Remove the hair spray with warm water and an abrasive pad before sanding in preparation for primer/paint.
Make sure to use wax in the mold, then apply the heavy hold hair spray before making your part. You'll find this method to be extremely successful your first time out.
