Preferred hydrophobically modified Si-containing polyamines are particularly useful for treating aluminosilicate scale in difficult-to-treat industrial process streams, such as in the Bayer alumina process streams, nuclear waste streams and kraft paper mill effluent streams.

Abstract

A resin-rich peel ply (11) that does not leave behind residual fibers after peeling and can work well with different resin-based composite substrates (10) The resin-rich peel ply (11) is composed of a woven fabric (lib) impregnated with a resin matrix (11a) different from the resin matrix of the composite substrate (10). The peel ply (11) is designed such that, upon manual removal of the peel ply (11) from the composite substrate's (10) surface, a thin film of the peel ply resin remains on the composite substrate's surface to create a bondable surface capable of bonding with another composite substrate (12), but no fibrous material from the woven fabric remains on the same surface.

Abstract

Embodiments of the present disclosure present electrically conductive, thermosetting compositions for use in surfacing films and adhesives. The surfacing films possess enhanced electrical conductivity, comparable to metals, without the use of embedded metal screens or foils. Such surfacing films may be incorporated into composite structures (e.g., prepregs, tapes, and fabrics), for example, by co-curing, as an outermost surface layer. In particular, compositions formed using silver flakes as conductive fillers are found to exhibit very high electrical conductivity. For example, compositions including greater than 45 wt. % silver flake exhibit resistivities less than about 55 mΩ/sq. In this manner, the surfacing films as an outermost conductive layer may provide lighting strike protection (LSP) and electromagnetic interference (EMI) shielding when used in applications such as aircraft components.

Composite materials having favorable acoustic and vibration damping properties, while maintaining or improving other composite mechanical properties, include an interleaf layer comprising at least two different nonwoven materials in a specific sequence such that a gradient is formed in the z direction upon curing or an interleaf with a compositional gradient within its structure such that a resin interpenetration gradient is achieved upon curing. Composite materials that contain multilayered nonwoven interleaves are useful, for example, in structures found in aircrafts, such as fuselage skins, stringers and frames. Also contemplated are methods of making the composite material and the structures and aircrafts that contain the composite material.

Abstract

Embodiments of the invention are directed to resin- soluble thermoplastic veils for use in liquid resin infusion processes, methods of manufacturing resin-soluble thermoplastic veils for use in liquid resin infusion processes, and methods of manufacturing composite articles using resin-soluble thermoplastic veils for use in liquid resin infusion applications. The resin- soluble thermoplastic veils according to embodiments of the invention and of which function as a toughening agent in composites having the veil incorporated therein have improved characteristics including, but not limited to, increased uniformity and decreased thickness relative to prior art veils. These characteristics translate into improvements in the processing of a composite article including, but not limited to, a substantial or complete elimination in premature dissolution of the veil during cure. The resultant composite article also realizes improvements including, but not limited to, distribution evenness of the toughening agent throughout the composite.

Abstract

Embodiments of the present disclosure are directed to the targeted deposition of particles below 100 microns onto a substrate such as a film, tape, adhesive, fabric, fibers or a combination thereof. The targeted deposition may be accomplished by a dual- component electro-static deposition process. In one embodiment, the substrate having at least one layer of particles thereon may be combined with a prepreg. Prepregs manufactured according to embodiments of the invention may be used to manufacture composites with more robust mechanical and strength characteristics relative to conventional composites manufactured using conventional prepregs in addition to providing improved processed performance during the manufacture of the particle- coated substrate. In another embodiment, targeted deposition may be applied directly to a composite article to achieve similar benefits.
