Abstract: A hybrid metal composite (HMC) structure comprises tiers comprising fiber composite material structures, and additional tiers longitudinally adjacent one or more of the tiers and comprising perforated metallic structures and additional fiber composite material structures laterally adjacent the perforated metallic structures. Methods of forming an HMC structure, and related rocket motors and multi-stage rocket motor assemblies are also disclosed.

Abstract: Processes are described for isomerizing one or more C4-C24 alpha olefins to produce an isomerization mixture comprising one or more C4-C24 internal olefins comprising contacting an olefinic feed comprising the one or more C4-C24 alpha olefins with a catalyst under isomerization conditions, wherein the catalyst comprises a microporous crystalline aluminosilicate selected from the group consisting of ZSM-5, ZSM-23, ZSM-35, ZSM-11, ZSM-12, ZSM-48, ZSM-57, and mixtures or combinations thereof, and wherein the microporous crystalline aluminosilicate has a SiO2/Al2O3 molar ratio of less than or equal to about 100. The resulting isomerization mixture typically exhibits a lower pour point and maintained biodegradability properties as compared to the olefinic feed, and is particularly useful in drilling fluid and paper sizing compositions.
