Abstract
A method of manufacturing a mold adapted to be used for casting bodies of ber-reinforced composites. A model of the body to be cast is prepared and coated with a one piece dense shell of refractory metallic oxide deposited by plasma or flame spraying and the model is then separated from the shell by conventional physical or chemical treatment.
