  • Fibrous polyacrylonitrile reinforcing mixture for friction product applications, and method of making same
    Patent number: 4886706
    Abstract: An improved fibrous polyacrylonitrile mixture for use in friction products enables the production of low resiliency preforms by mixing an additive with a polyacrylonitrile wet gel. The additive is incorporated into the fiber in extremely large amounts. The additive is a member selected from the group consisting of:(a) polyethylene glycol esters of pelargonic acid; or(b) polyethylene glycol esters of enanthic, caprylic or capric acids; or(c) blends of polyethylene glycol esters of enanthic, caprylic, pelargonic, or capric acids; or(d) blends of polyethylene glycol esters of carboxylic acids derived from natural products containing at least 50% by weight of carboxylic acids containing less than 14 carbon atoms; or(e) reaction products of ethylene oxide and carboxylic acid amides wherein at least 70% of the acids from which the amide is derived contain between 16 and 20 carbon atoms.

  • Method of making reinforced materials having an improved reinforcing material therein
    Patent number: 4866109
    Abstract: The invention is specifically concerned with an improvement in the process of manufacturing reinforced materials. The reinforced materials are conceived to include a wide variety of materials, the most notable being high density compressed gaskets. The improvement comprises mixing a cut solid (generally a cut fiber) with a body material to produce the reinforced materials. The solid is cut into particulates of highly variable size, the range in the size of the particulates being adjusted to optimize the characteristics of the resulting reinforced material. The cut solid is produced utilizing comminuting machines previously used for the recycle of waste products.
