摘要： A protective, impact resistant material and method, the material comprising a fabric of thermoplastic polymeric fibers having a strength of at least 0.4 GPa and an elastic modulus of at least 5 GPa and a matrix of polymeric material disposed in the interstices between the fibers, the matrix having an elastic modulus in the range 0.2 to 3.times.10.sup.6 psi. The polymeric fibers can be gel spun polyethylene, polypropylene, nylon, polyvinyl alcohol and polyethylene terephthalate. In a second embodiment, the matrix is derived from the fabric. The method of making the material comprises providing a matrix of melted polymeric material transparent to energy of a predetermined type and having a predetermined melting temperature, placing a fabric of polymeric fibers having a melting temperature higher than the melting temperature of the matrix in the matrix, applying a pressure of 1000 to 6000 psi to the fabric disposed in the matrix, then raising the temperature to the melting temperature of the fabric for the minimum time required to cause consolidation of the fabric and the matrix and rapidly cooling the consolidated fabric and matrix to a temperature below the melting temperature of the fabric. In accordance with a second embodiment there is provided a fabric of polymeric fibers as in the first embodiment which is operated upon as in the first embodiment to cause melting of a sufficient portion of the fabric to fill the interstices between the fibers of the fabric and the fabric is then rapidly cooled to a temperature below the melting temperature of the fabric.

摘要： An infrared lens assembly may comprise a lens set (32) including one or more refractive lenses. The refractive lens may be positioned along an optic axis (30) to receive infrared radiation. The lens set (32) may be designed to focus infrared radiation of a scene (14) at an image plane (15). An athermalization element (34) may be positioned along the optic axis (30) in optical communication with the lens set (32). The athermalization element (34) may include an infrared transmitting member (40) supporting a diffractive pattern (42). The infrared transmitting member (40) may comprise an infrared transmitting polymer. The diffractive pattern (42) may compensate for temperature induced changes in a focal length of the lens set (32) to maintain infrared radiation of the scene (14) in focus at the image plane (15).

摘要： A method of removing B.sub.2 O.sub.3 encapsulant from a structure which includes providing a structure having a melting temperature and having a layer of B.sub.2 O.sub.3 thereon. This structure with the layer of B.sub.2 O.sub.3 thereon is placed in a chamber at a temperature in excess of 400.degree. C. and below the melting temperature of the structure and at some pressure and the pressure in the chamber is decreased, preferably to about -14.7 psig, until the B.sub.2 O.sub.3 foams. Then the temperature in the chamber is lowered to below 400.degree. C. and preferably to about ambient temperature external of the chamber. The structure with the B.sub.2 O.sub.3 thereon is washed in an alcohol, preferably one of methanol and isopropanol, after the B.sub.2 O.sub.3 has foamed and the structure is then washed with the B.sub.2 O.sub.3 thereon after the B.sub.2 O.sub.3 has foamed in a liquid non-reactive with the structure to remove the B.sub.2 O.sub.3 from the structure, preferably water.
