A deformable, coated radius filler composed of a continuous or elongated fibrous structure and a tacky, resin surface coating formed by pulling a dry, continuous or elongated fibrous structure through a heated resin bath. The coated radius filler has an inner portion that is substantially free of resin and the resin surface coating has a substantially uniform thickness.

A liquid binder composition for binding fibrous materials in the fabrication of resin-infusible preform is disclosed. The binder composition is an aqueous dispersion containing (a) one or more multifunctional epoxy resins, (b) at least one thermoplastic polymer, (c) one or more surfactants selected from anionic surfactants, nonionic surfactants, and combinations thereof, (d) water, and is essentially free of organic solvents. Also disclosed is an emulsification process for producing the liquid binder composition.

Binder-treated fibrous materials

A dry, fibrous tape for use in an automated placement process such as ATL or AFP and a preform produced therefrom. The preform is configured for resin infusion. The tape contains a layer of unidirectional fibers, at least one nonwoven veil bonded to one side of the fiber layer, and at least binding materials present within the tape. The preform produced from laying down such tape exhibits a low-bulk property that is close to the final thickness of the cured fiber-reinforced resin article and no further consolidation or compaction is required.

Dry fibrous tape for manufacturing preform

Disclosed herein is a dry, self-supporting fibrous material, the fibers of which have been treated with a binder composition. The fibrous material can be slit into tapes or tows that are suitable for use in an Automated Tape Laying (ATL) or Automated Fiber Placement (AFP) process. This fibrous material is suitable for forming preforms which are configured to receive a matrix resin by resin infusion in the manufacturing of structural composite parts.

Dry fibrous material for subsequent resin infusion

Liquid binder composition for binding fibrous materials

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.

A plurality of thermoplastic composite structures are laminated to each other in a lay-up arrangement to form a laminate. Each thermoplastic composite structure is composed of a core composite layer and a surface layer polymer applied to opposing surfaces of the core composite layer. The core composite layer is composed of a fibrous substrate and one or more high performance polymers, which crystallize at a faster rate than the surface layer polymer.

Thermoplastic composites and methods of making and using same

A thermoplastic polymer toughening material in the form of polymeric fibers produced by mixing at least one epoxy curing agent and a thermoplastic polyaromatic polymer to form an admixture, and producing polymeric fibers from the admixture, wherein the thermoplastic polymer toughening material does not include an epoxy resin, and is soluble in an epoxy resin at a temperature lower than a dissolving temperature required by the thermoplastic polymer toughening material without epoxy curing agent.

Multifunctional additives in engineering thermoplastics

A toughening agent for use in making composites comprises an epoxy curing agent and a thermoplastic. Compositions, composites that comprise the toughening agent and associated methods of making and using the toughening agent are also disclosed.

Thermoplastic composites having a core composite layer including a fibrous substrate and one or more high performance polymer, and a surface layer polymer applied to at least one surface of the core composite layer, which forms a polymer blend with the high performance polymer thereby imparting improved toughness and processing times, and methods for making and using same, are provided herein.

A near netshape carbon preform is provided comprising a polar woven fabric of a plurality of carbon yarns, said polar woven fabric having a helical shape and an adjustable fiber orientation distribution, said polar woven fabric being laid down, turn by turn, into a near net shape preform, and each layer of said fabric being needled to produce a near net shape preform with increased interlaminar strength, an adjustable fiber orientation distribution and enhanced thermal conductivity. A method for manufacturing a near net shape carbon preform with a polar woven substrate is also disclosed.
