Rapid manufacturing of tailored preforms

A method for rapid manufacturing of three dimensional discontinuous fiber preforms is provided. The method includes the deposition of a polymeric material containing fibers on a surface to form a tailored charge for compression molding. The reinforced polymeric material may be a thermoplastic or a reactive polymer with viscosity low enough to allow flow through an orifice during deposition, yet high enough zero shear viscosity to retain the approximate shape of the deposited charge. The material can be deposited in a predetermined pattern to induce the desired mechanical properties through alignment of the fibers. This deposition can be performed in a single layer or in multiple layers. The alignment is achieved passively by shear alignment of the fibers or actively through fiber orientation control or mixing. The fibers can be of the desired material, length, and morphology, including short and long filaments.

Nicotine lozenge

A nicotine lozenge includes a body that is partially or wholly receivable in an oral cavity. The body includes a soluble-fiber matrix and nicotine or a derivative thereof dispersed in the soluble-fiber matrix. A nicotine lozenge may include at least 40 weight percent of soluble fiber. Soluble fiber in a nicotine lozenge may include maltodextrin. The nicotine lozenge is adapted to release the nicotine or a derivative thereof from the body when the body is received within the oral cavity of an adult consumer and exposed to saliva. A method of making nicotine lozenges includes forming a molten mixture of at least 40 weight percent soluble fiber, nicotine, and less than 15 weight percent water while maintaining a mixture temperature of less than 150° C. and portioning the molten mixture into a plurality of nicotine lozenges. The ingredients can be mixed to form the molten mixture in an extruder.

Method for producing thermally crosslinkable polymers in a planetary roller extruder

A method for producing thermally crosslinkable polymers in a planetary roller extruder is presented. The planetary roller extruder has a filling part and a compounding part made of a roller cylinder region that comprises at least two, preferably at least three coupled roller cylinders, planetary spindles of which are driven by a common central spindle. The polymers are supplied in a plasticized state. The filling part is supplied with a vacuum. The flow temperatures of the central spindle and the at least two roller cylinders under a vacuum are set such that the polymers to be degassed remain in the plasticized state. One or more liquids, such as thermal crosslinkers, crosslinking accelerators, dye solutions, or dye dispersions, are metered to the plasticized polymers downstream of the vacuum degassing, preferably in a continuous manner. Finally, the resulting mixture is directly supplied to a coating assembly.
