(alpha, omega) hydroxyl terminated polysiloxane first soft segments having an average molecular weight of between about 2500 grams per mole to about 10,000 grams per mole, and one or more diisocyanate species, together to form a first reaction product; mixing the first reaction product and one or more low molecular weight diol or diamine chain extenders each having an average molecular weight of less than 400 grams per mole, together in a solvent to form a segmented copolymer; and, removing the solvent.

Abstract: Methods and formulations for modified silicone resins of Formula (I) are presented: The R1, R2, and R3 are each independently selected from a group consisting of H, alkyl, alkenyl, alkynyl, and aryl; n ranges from 1 to 10; m ranges from 1 to 200; and p ranges from 2 to 1,000. The elastomeric materials prepared from modified silicone resins display robust mechanical properties following prolonged exposure to high temperatures (e.g., 316° C. or higher).

Abstract: An composite prepreg ply which can be designed to exhibit desired electrical properties without loss of structural integrity or the addition of parasitic weight, and a method of preparing the composite prepreg ply. The composite prepreg ply includes: (i) a low dielectric cloth substrate having a metal layer adherent on both sides thereon, the metal having been selectively removed from at least one portion of at least one side of the cloth, such that there is at least one area of cloth without any metal adherent thereon; (ii) a layer of encapsulant resin material adherent on the metal layer; (iii) a resistive resin layer containing a filler material dispersed in a carrier resin, the resistive resin layer adherent on desired areas the cloth without any metal adherent thereon, and (iv) an impregnating resin covering one or both outermost surfaces of the encapsulant resin material and the resistive resin layer.

Abstract: A compact roller system including a housing for a plurality of disks, each independently supported within a support member having sides which partially envelop the external peripheries of the disk. The disks do not separate or dislodge from their corresponding support members, yet the disks are capable of rotating within their corresponding support members. Each disk/support member shifts radially within the housing to accommodate the varying contours of a workpiece surface. The disks, in combination with their corresponding support members, apply an adjustable, evenly distributed compaction force to the workpiece surface through internal pressurization of the housing with a compressed gas.
