摘要： Coating compositions having a polymeric binder and a stabilizer composition including at least one of a UV absorber, a hindered amine light stabilizer (HALS), or an inorganic UV blocker are provided herein, wherein said coating compositions are more resistant to discoloration when exposed to UV-C (190-280 nm) light compared to the coating compositions in the absence of the stabilizer composition. Thus, a method of stabilizing a coating composition against the deleterious effects of UV-C (190-280 nm) light includes adding to the coating composition an effective amount of such a stabilizer composition, wherein the coating composition is made more resistant to discoloration when exposed to UV-C (190-280 nm) light compared to the coating composition in the absence of the stabilizer composition. Coated articles can be made from the coating composition, and methods of making stabilized coating films include adding the stabilizer composition to the coating composition.

摘要： A controlled shear vacuum forming method that includes forming a three-dimensional (3D) structure from a preform material on a molding tool using restraints during vacuuming to prevent wrinkling. The restraints are withdrawn during vacuuming to allowing the preform material to come into contact with the sidewalls of the molding tool in a gradual manner. Such forming method is particularly suitable for forming wing spars with bent sections and/or curved contours.

摘要： A spinneret assembly for spinning polymeric fibers, including: (a) a cap provided with an inlet port and a flared lower surface that flares outwardly from the inlet port in the direction of flow; (b) a spinneret having numerous spinning flow channels through its thickness; (c) a filter freely resting on the spinneret; and (d) a flow guide with a tapered geometry mounted in a cavity defined by the cap and the spinneret. The flow guide has an apex facing the inlet port, a base facing the filter, and one or more side surfaces tapering up to the apex. A diverging flow passage is defined by the tapering side surface(s) of the flow guide and the cap's flared lower surface. The base of the flow guide is spaced apart from an upper surface of the spinneret, creating a space that is in fluid communication with the divergent flow passage.

摘要： A method for surface preparation of a composite substrate prior to adhesive bonding. The surface preparation method includes applying a resin-containing peel ply onto a composite substrate, followed by co-curing. The resin-containing peel ply contains a non-removable textile carrier and a removable woven fabric embedded therein. After co-curing, the peel ply is removed from the composite substrate such that the removable woven fabric is removed but the non-removable textile carrier and a film of residual resin remain on the composite substrate, thereby creating a modified, bondable surface on the composite substrate. The composite substrate with the modified surface can be bonded to another composite substrate, whereby the textile carrier remains an integrated part of the final bonded structure.
