Abstract: A method of making high strength, low thermal expansion thin composite structures of uniform thickness is disclosed. A plurality of resin impregnated graphite fiber sheets are laminated together to provide composite preforms. A plurality of the preforms are then bonded together in a pseudoisotropic arrangement between parallel plates. The resulting structures are especially useful as substrates for flat or slightly contoured mirrors.
