Method of fabricating a reinforced material

Abstract: A METHOD FOR PRODUCING A COMPOSITE MATERIAL AND THE IMPROVED MATERIAL STRUCTURE WHICH IS COMPOSED OF A MATRIX AND A PLURALITY OF REINFORCING ELEMENTS WHICH ARE COMBINED WITHIN SAID MATRIX TO FORM A UNITARY STRUCTURE THREWITH. THE REINFORCING ELEMENTS MAY COMPRISE METAL WIRES, FILAMENTS OR WHISKERS DISPOSED WITHIN A CERAMIC MATRIX OR SUBSTRATE WHEREIN THE FILAMENTS SERVE TO REINFORCE THE MATRIX MATERIAL. THE PROCESS INVOLVES CONTINUOUSLY FEEDING A PLURALITY OF FILAMENTS AND MATRIX MATERIAL TO A DIE AND THEREAFTER PREDETERMINANTLY FORMING A CONTINUOUS SHAPE THEREOF. IN ONE FORM, THE FILAMENTS OR WHISKERS ARE CONTINUOUSLY FORMED AS THEY ARE FED TO THE DIE OR MOLD EMPLOYED TO FORM THE COMPOSITE MATERIAL, THE FILAMENTS MAY ALSO BE FABRICATED OF GLASS, CERAMIC, POLYMERS OR CARBONIZED MATERIAL WHICH MAY BE RANDOMLY OR EVENLY DISPERSED WITHIN THE MATRIX MATERIAL.

The manufacture and properties of oxide fibers

Abstract: A method has been developed at the laboratory for producing refractory oxide fibers with a diameter of 0.5–0.06 mm by the extrusion method. These fibers can be used in the manufacture of composite materials with a high mechanical strength. Fibers with a diameter of 60 μ have been obtained. After heat treatment and the subsequent measurement of mechanical properties these fibers were used in producing the composite materials: ceramic matrix + ceramic fiber, metallic matrix + ceramic fibers, etc.
