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 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 The restraints are withdrawn during vacuuming to allowing the preform material to come into contact with the sidewalls of the molding tool in a gradual manner.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： Disclosed herein is a solvent-based bonding primer composition containing one or more organic solvents, one or more epoxy resins, one or more curing agents, a silane compound, and a low amount of core-shell rubber particles in nanometer size, submicron or micron size. Also disclosed is a method of applying the solvent-based bonding primer composition onto a metallic surface of a first substrate prior to bonding the metallic surface to a second substrate via a curable adhesive.

摘要： A flexible, self-supporting hybrid veil that is permeable to liquid and gas. The hybrid veil includes: (a) intermingled, randomly arranged fibres in the form of a nonwoven structure; (b) particles dispersed throughout the nonwoven structure, wherein a majority of the particles are penetrating through the thickness of the nonwoven structure; and (c) a polymeric or resinous binder present throughout the veil. Such hybrid veil can be incorporated into composite laminates, prepregs, fabrics and fibrous preforms.

摘要： A multifunctional surfacing material capable of providing lightning strike protection (LSP) and burn-through resistance. In one embodiment, the multifunctional surfacing material is composed of a conductive layer positioned between two resin layers, at least one of which contains one or more fire retardant compounds. In another embodiment, the multifunctional surfacing material is composed of a conductive layer positioned between two resin layers one of which is a thermally-stable layer. The surfacing material is co-curable with a composite substrate, e.g. prepreg or prepreg layup, which contains fiber-reinforced matrix resin.

摘要： A curable composition containing more than 80% by weight of a blend of benzoxazines, wherein the blend includes (A) one or more multifunctional benzoxazines and (B) a liquid, non-halogenated monofunctional benzoxazine. This composition has been found to be stable at high temperatures, e.g. 180° C.-250° C., and suitable for making composite materials using conventional techniques such as prepregging and liquid resin infusion.
