    摘要： A method of making fiber reinforced glass composite articles utilizes preregnated preforms which are bound with a temporary plastic binder. The binder is removed in a gradient oven and the frit or preform is drawn through a pultrusion die assembly heated to the degree necessary to render the frit workable. Deformation in the heated die assembly is maintained during cooling, resulting in a formed glass composite article.

    摘要： A method of producing fiber reinforced glass composites of complex shapes (e.g. having curved portions such as cylindrical) is disclosed. A continuous length of fiber, such as silicon carbide, is passed through a slurry of glass powder and a carrier liquid containing a polymeric binder to impregnate the fiber. The impregnated fiber is next dried and woven into a predetermined structural shape. Plies of the woven fiber cut to near net shape may also be stacked into the desired shape. The thus laid fibers are hot pressed into a fiber reinforced glass matrix composite article having glass matrix distributed substantially uniformly therethrough and multiaxial strength in at least three mutually exclusive perpendicular directions.

    摘要： The present invention discloses a method of making fiber reinforced glass, glass-ceramic or ceramic matrix composite articles. The method comprises forming the matrix material into fibers and then into yarn which is woven or knitted into cloth. The matrix cloth is then cut into preformed shapes and interleaved with preformed pieces of fabric which have been woven or knitted from yarn containing the fiber reinforcement. The interleaved preformed structure is then placed in a die and densified under pressure and temperature to form the composite article. Also disclosed is a method wherein the yarn of reinforcing fiber and matrix fibers is woven or knitted together to form a hybrid cloth. This hybrid cloth is then cut into predetermined forms and placed in a die and densified under heat and pressure to form the composite article. Further, a hybrid cloth comprising yarn of both matrix and reinforcing fibers may be formed and then cut into predetermined forms, placed in a die and densified under heat and pressure forming a component article. In addition, these fibers and yarns may be formed into near net structures which can then be densified to form complex composite articles.

    摘要： A method for molding fiber reinforced articles with superior mechanical properties by injection molding. The method comprises heating a mixture of molding compound and chopper fiber to produce highly viscous substance. Pressure is applied to force the substance through an elongated injection slot oriented perpendicular to the major axial dimension of the finished article, causing the fiber planes to become oriented in a unique whorled, accordion like manner. The unusual fiber plane orientation reinforces the article such that it is resistant to crack propagation.
