Abstract: The present invention provides a method for manufacturing an air bearing with discreet orifices designed to facilitate a non-contact interface between surfaces. The process involves using a mold wherein wires or filaments are placed to form air channels within a cast. Various materials, such as silicone, steel, and composites, can be used for the mold. After casting and curing the material, the wires are removed, leaving precisely defined channels that allow air to flow through, creating a cushion of air that maintains a gap between the bearing and the surface it operates on. This gap can be adjusted by changing the air pressure or the number of channels. The bearing components may be further machined or secured in a housing connected to an air source, enabling the bearing to hover and operate efficiently in various applications. The invention allows for multiple configurations of the air channels to optimize airflow distribution as required.

Abstract: The present disclosure provides a fibrous preform, comprising an annulus having at least one of an outer diameter portion or an inner diameter portion, the outer diameter portion extending radially inward from an outer diameter of the fibrous preform and the inner diameter portion extending radially outward from an inner diameter of the fibrous preform. In various embodiments, the fibrous preform further comprises a medial diameter portion disposed between the outer diameter and the inner diameter, wherein the medial diameter portion comprises a first needling profile, and the at least one of the outer diameter portion or the inner diameter portion comprises a second needling profile. In various embodiments, the first needling profile is less than the second needling profile.
