One or more techniques and/or systems are disclosed for a dry-type lubricant for use in a dry product hopper to help improve dry product flow and to improve anti jamming properties of the dry product. The example lubricant can comprise a hydrophilic fiber, such as cellulose, having a width to length aspect ratio that provides a thin fiber. A plurality of hydrophobic particles are deposited on the surface of the fiber, resulting in a fiber surface exhibiting amphiphobic properties. Further, the fiber can operably absorb water, and then releases the absorbed water to the surface of the fiber under mechanical stress, such as when mixed with a product in a hopper. This can result in the water being disposed on the surface of the fiber, to provide lubrication to a product in a hopper to improve flow and anti jamming characteristics of the product in the hopper.

A molding process of a co-cured short-fiber resin-based damping composite material and a molding part. Different from a traditional centrifugal processing process of a thin-walled tube of a resin-based composite material, the process uses raw materials including three kinds of materials with different densities and including two kinds of short-fiber epoxy resin with different densities and a damping material. During centrifugal molding, the three kinds of materials are made into fluids to be respectively injected at a uniform speed in three times according to the sizes of the densities. Layering is performed by using different centrifugal forces applied to the three kinds of materials. Co-curing is performed according to a resin curing process after the three kinds of materials are stably distributed, and a tubular thin-walled part of the embedded co-cured short-fiber resin-based damping composite material with a uniform wall thickness is obtained.
