Methods and compositions, and components comprising the compositions, are disclosed relating to improved resin-based adhesives comprising encapsulating at least a catalyst compound. Further methods and compositions are disclosed relating to encapsulated catalysts in uncured resin-based adhesives, said encapsulated catalysts configured to release the catalyst compound and cure the uncured resin-based adhesive on-demand.

Encapsulated catalyst for aerospace grade resin systems

Methods and systems and components made according to the methods and systems, are disclosed relating to improved curing methods for epoxy resin-containing composite prepreg materials, wherein the composite prepreg materials are exposed to a flow of ammonia-containing compounds to fully cure the composite prepreg materials at substantially ambient temperatures and pressures.

Methods, systems and apparatuses for curing epoxy-containing prepreg composite assembly

A structural assembly and methods are provided to facilitate corrosion inspection, such as in those regions of a structure that may otherwise be visibly inspected only following at least partial disassembly of the structure. The structural assembly may include a structure and a coating disposed upon at least a portion of the structure that has optical properties that change in response to corrosion. The structural assembly may also include a fiber optic sensing network including a plurality of optical fibers and a sensor. The plurality of optical fibers are configured to expose the coating to incident optical signals and to receive responsive optical signals at least partially dependent upon any change in the optical properties of the coating. The sensor is configured to receive the responsive optical signals from the plurality of optical fibers. This sensor may also be configured to analyze the responsive optical signals to detect corrosion.

Structural assembly and methods for facilitating corrosion inspection

A method of non-destructively determining the amount of ultraviolet degradation of a surface and/or paint adhesion characteristics of the surface corresponding with UV damage including determining a physical property of a composite material/surfacing film by providing a series of composite materials/surfacing films which are subjected to increasing UV light exposure to create a set of UV damage standards, collecting mid-IR spectra on those standards, performing data pre-processing and then multivariate calibration on the spectra of the composite materials/surfacing films, and using that calibration to predict the UV damage for samples in question.

Method for performing IR spectroscopy measurements to quantify a level of UV effect

A filter membrane includes a substrate, a polymer layer provided on the substrate and a plurality of filter openings each having a width of from about 2 nanometers to about 5 nanometers provided in the polymer layer. A method of controlling pore size of a filter membrane and a method of decontaminating a filter membrane are also disclosed.
