ORIGIN OF THE INVENTION
This invention described herein was made in the performance of work under a NASA contract and is subject to the provisions of Section 305 of the National Aeronautics and Space Act of 1958, Public Law 85-568 (72 Stat. 435; 42 U.S.C 2457).

| Abstract: |
A method for forming a glove attachment principally for the palm of an astronaut glove to enhance the gripping area of the palm without detracting from the flexibility and utility of the glove. The attachment is a composite construction formed from a layer of silicone rubber having an outer surface with a friction configuration and an another layer of silicone rubber in which a meta-aramid mesh fabric is embedded prior to curing. The method of construction involves the use of a mold with a friction configuration surface. A first layer of silicone rubber or sealant is disposed in the mold and allowed to set for an hour. A second layer of silicone rubber or sealant is layered over the first layer and leveled. A meta-aramid mesh fabric is embedded into the second layer and the composite is permitted to cure. When cured, a configured area of the composite construction is glued or stitched to the palm area of the glove.

First Claim:

We claim:
1. A method of constructing a thin, lightweight, flexible, durable composite structure that is functional over a wide range of temperatures in a space environment for attachment to glove areas for enhancing frictional characteristics including the steps of:
- constructing a mold with a bottom surface arranged in a frictional pattern,
- applying a release agent to the mold for casting;
- disposing a first liquid silicone rubber compound which can set at ambient temperatures in the mold to form a first layer of material of selected uniform thickness of approximately 18 to 20 mils;
- permitting the first liquid silicone rubber to set to a gel state,
- disposing a second liquid silicone rubber compound which can set at ambient temperatures over the first liquid silicone rubber compound and forming the second liquid silicone rubber compound to a selected uniform thickness of approximately 18 to 20 mils;
- overlaying the second liquid silicone rubber compound with a meta-aramid mesh fabric having a thickness less than the thickness of said second liquid silicone rubber compound;
- forcing the fabric into said second liquid silicone rubber compound to extrude said second liquid silicone rubber compound through the fabric mesh;
- smoothing off the surface of said second liquid silicone rubber compound whereby the thickness of the first and second silicone rubber layers is between 36 and 40 mils; and
- curing said first and second silicone rubber compounds.
