Title: Rita Baranwal: Innovator in Composite Materials

Introduction

Rita Baranwal is a prominent inventor based in Glenshaw, PA (US). She has made significant contributions to the field of composite materials, particularly in the development of innovative techniques for fabricating high-quality ceramic composites. With a total of 2 patents, her work has garnered attention for its potential applications in various industries.

Latest Patents

One of her latest patents is the "Resin Infiltration Transfer Technique." This process has been developed for fabricating composite structures using either reaction forming or polymer infiltration and pyrolysis techniques to densify the composite matrix. The matrix and reinforcement materials of choice can include, but are not limited to, silicon carbide (SiC) and zirconium carbide (ZrC). This novel process can be used to fabricate complex, net-shape or near-net shape, high-quality ceramic composites with a crack-free matrix.

Another significant patent is the "Reaction-Forming Method for Producing Near Net-Shape Refractory Metal Carbides." This method involves the fabrication of a glassy carbon preform by casting an organic, resin-based liquid mixture into a mold and subsequently heat treating it in two steps. This process cures and pyrolizes the resin, resulting in a porous carbon preform. By varying the amounts of the constituents in the organic, resin-based liquid mixture, control over the density of the carbon preform is achieved. The glassy carbon preform is then placed on a bed of refractory metal or refractory metal-silicon alloy, where it undergoes a reaction to form the refractory metal carbide.
