1. A method for manufacturing optical and microwave reflectors, comprising:
placing an assembly comprising a resin-infiltrated tendrillar mat structure on a mandrel;
placing a pre-impregnated carbon fiber (CF) lamina on top of the tendrillar mat structure;
placing the assembly in a vacuum device so as to squeeze out excess resin;
and placing the assembly in a heating device so as to cure the tendrillar mat structure together with the CF lamina, forming the CF laminae into a laminate that combines with the tendrillar mat structure to create a cured assembly, the cured assembly having a loading of between approximately 20% and approximately 50%, the cured assembly exhibiting a thermal strain that is reduced by two to five times relative to pure resin.
