Abstract: Provided herewith is a process for improving tensile strength of precursor PAN fiber during the spinning stage in the manufacturing process. According to the process of the present invention, precursor fiber is made denser as it enters each wash bath. This progressive densification approach is useful for all PAN precursor bath draw/wash processes where a need for careful control of fiber network density and structure is required for improved carbon fiber properties.

Abstract: Curable prepregs possessing enhanced ability for the removal of gases from within prepregs and between prepreg plies in a prepreg layup prior to and/or during consolidation and curing. Each curable prepreg is a resin-impregnated, woven fabric that has been subjected to a treatment to create an array of openings in at least one major surface. Furthermore, the location of the openings is specific to the weave pattern of the fabric.

Abstract: An electrically conductive surfacing material capable of providing sufficient conductivity for lightning strike protection (LSP) and/or electromagnetic interference (EMI) shielding is disclosed. The conductive surfacing material is a multi-layered structure having a very thin conductive layer (e.g. solid metal foil) and a resin film formed on at least one surface of the conductive layer. The resin film is formed from a curable resin composition containing an epoxy novolac resin, a tri-functional or tetra-functional epoxy resin, ceramic microspheres, a latent amine-based curing agent, particulate inorganic fillers; and a toughening component. Optionally, the resin film further includes conductive additives to increase electrical conductivity of the surfacing material. The resin film exhibits high Tg as well as high resistance to paint stripper solutions. Furthermore, the conductive surfacing material is suitable for co-curing with fiber-reinforced resin composite substrates.

Abstract: 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.

Abstract: A method for producing a modified form of an aromatic amine compound represented by the following structure I: where A is an amine group —NHR, R is independently selected from hydrogen, linear and branched alkyl groups having 1 to 6 carbon atoms, preferably A is NH2; X is a halogen selected from Cl, Br, F, I, and At, or hydrogen (H). The method includes heating the aromatic amine compound, in its initial crystalline form, to a temperature above its melting point in order to obtain a molten material, then cooling the molten material to a temperature below the melting point of the crystalline compound so as to produce an amorphous, glassy form of the aromatic amine compound. The modified aromatic amine compound is suitable as a curing agent in resin compositions that are used for fabricating fiber-reinforced composites.

Abstract: A gas phase surface treatment for treating carbon fiber including (a) exposing a carbon fiber to a gaseous oxidizing atmosphere to form a modified carbon fiber with an oxidized fiber surface; followed by (b) exposing the oxidized fiber surface to a gaseous nitrogen-containing atmosphere to form a modified carbon fiber with a nitrogen-enriched surface, wherein the nitrogen-enriched surface exhibits an increase in surface nitrogen to surface carbon (N/C) ratio as compared to the surface of the carbon fiber prior to exposure at (a). Steps (a) and (b) are carried out continuously without any additional intervening surface treatment.
