Abstract: A cap assembly for enclosing an end portion of a bolt fastener includes a first cap member which includes a bore and a surface positioned within the bore which defines first threads and the first cap member also includes an external surface which defines second threads. A second cap member includes a sidewall which defines a receptacle with an opening which provides access to an interior of the receptacle and the sidewall includes an interior surface which defines third threads compatibly configured to engage the second threads. The third threads are positioned along the interior surface of the receptacle extending along a length of the receptacle a first distance and the second threads are positioned along the external surface of the first cap member extending along a length of the external surface a second distance wherein the first distance is greater than the second distance.

Abstract: The present application is directed to polysulfide sealant formulations, application of such sealants, and methods for reducing the density of polysulfide sealant formulations.

Abstract: Provided is a method of forming a shaped structure. The method includes coupling a first section of a mold to a second section of the mold such that a mold cavity is defined, wherein a cross-sectional shape of the mold cavity corresponds to a cross-sectional shape of the shaped structure and wherein at least one of the first section of the mold and the second section of the mold comprise a soluble material; at least partially filling the mold cavity with a curable polymer; and curing the curable polymer in the mold cavity to make the shaped structure.
