Abstract:
The present invention relates to a low-friction member imitating shark skin and a manufacturing method therefor, the low-friction member implementing a structure similar to shark skin and having riblets by stacking, in layers, composite particles formed by attaching spherical particles on the surfaces of plate-shaped particles, and thus the low-friction member has excellent low-friction characteristics. The present invention comprises: a base plate; plate-shaped particles stacked in layers on the surface of the base plate in the form of scales; and a plurality of spherical metal lubricating particles having a size smaller than that of the plate-shaped particles, and coated on the surfaces of the plate-shaped particles, wherein the metal lubricating particles are arranged in the form of a bridge connecting the base plate and the plate-shaped particles, and the plate-shaped particles to each other.
Abstract:
A self-lubricating composite material is disclosed. The self-lubricating composite material can include discontinuous polymer fiber segments dispersed within a woven matrix of semi-continuous thermoplastic fiber. The woven matrix can be embedded within a thermosetting resin. Also disclosed are methods of manufacturing the self-lubricating composite material.
Abstract:
A method of lubricating an expandable rubber bladder is described for use during a vulcanization of a green tire within a metal press. The method can include applying compositions in the form of emulsions of silicone oils to the inner surface of the green tires and/or to the outer surface of the vulcanization bladders to facilitate the molding-demolding thereof during the manufacture of the tires.
Abstract:
A curing formulation operative as a lubricant is provided that has a plurality of silicone polymer precursors constituting a majority by weight of the formulation, each of the plurality of the silicone polymer precursors has a single curable moiety. A crosslinker is provided for reaction with the single curable moiety of each of the plurality of silicone polymer precursors to yield a thermoplastic silicone polymer having a majority by total weight of silicone polymer being comb- or branched-polymer form as the lubricant. A process of lubricating an interface is provide that includes the application of an aforementioned composition to the interface. Upon allowing sufficient time for the formulation to cure in ambient temperature conditions, a thermoplastic silicone polymer is formed having a majority by total weight of silicone polymer being comb- or branched-polymer.
Abstract:
