Methods of compression resin transfer infusion are presented. A dry preform with a thermoplastic veil is placed onto a lower mold die. An upper mold die is placed over the lower mold die to create an infusion and cure tool having a sealed cavity holding the dry preform, the sealed cavity defining a gap, the gap corresponding to a cavity volume equivalent to an amount of resin to infuse the dry preform. Resin is injected into the gap of the sealed cavity while the infusion and cure tool is maintained at an infusion temperature. The upper mold die is lowered to infuse the dry preform to form a resin-infused preform. The resin-infused preform is cured within the infusion and cure tool to form a cured composite part, wherein curing occurs at a curing temperature higher than the infusion temperature.

Compression resin transfer infusion methods

A composite structure having a co-curable or co-cured coated epoxy-based composite material coated with a co-curable epoxy-based adhesive surfacing material layer and a polyurethane-based coating material layer, along with components and large objects including the co-curable or co-cured coated epoxy-based composite structures.

Composite coatings having improved UV and paint stripping resistivity and methods for making same

The present disclosure is directed to an exterior surface protective layer for protecting a composite structure from environmental conditions including: at least one curable film; such as at least two curable films, and an electrically conductive material, wherein the electrically conductive material comprises a wire-free electrically conductive material, and/or an electrically conductive polymer weave, wherein the at least one curable film includes at least one of polyurethane, polyimide, polyester or epoxy upon curing, and wherein a weight of the exterior surface protective layer ranges from about 0.02 pounds per square foot to about 0.1 pounds per square foot. An exterior surface protected composite structure and methods of forming an exterior surface protected composite structure are also provided.

Lightning strike protection

Co-curable epoxy-based composite materials coated with co-curable polyurethane-based coating materials to form co-curable and co-cured polyurethane coated epoxy-based composite materials, with the polyurethane-based coating materials comprising UV-stabilizer agents and cure control agents are disclosed, along with components and large structures comprising the co-cured materials.

Elimination of surfacing film and primer from composite substrates

The present disclosure is directed to a method for applying a multi-colored coating to a composite structure comprising applying a first co-curable film layer comprising a first color marking to a composite tool, applying a second co-curable film layer comprising a second color marking over the composite tool and at least partially over the first co-curable film layer to create a lay-up of a multi-colored marking, applying a composite structure over the lay-up of the multi-colored marking, and curing the lay-up of the multi-colored marking and the composite structure in a single curing step to create a cured multi-colored coating on the composite structure. A multi-colored coating for marking a composite structure and an aircraft part having a multi-colored marking are also provided.

Co-curable film layer application

The present disclosure is directed to a method for reactivating a co-cured film layer disposed on a composite structure, the method comprising applying a reactivation treatment composition comprising at least two solvents and a surface exchange agent comprising a metal alkoxide or chelate thereof to the co-cured film layer, and allowing the reactivation treatment composition to create a reactivated co-cured film layer, wherein the co-cured film layer was previously cured at a curing temperature greater than about 50&#xb0; C. A reactivated co-cured film layer and an aircraft part having a reactivated co-cured film layer are also provided.

Reactivation of co-cured film layers

An ultrasonic inspection system, method, and software. In one embodiment, the ultrasonic inspection system includes an ultrasonic probe that directs ultrasound waves into a structure from a front wall, and receives reflected waves to generate a response signal. The system further includes a processor that rectifies the response signal to generate a rectified signal, integrates a portion of the rectified signal within a detection time window to determine an energy sum, and generates output based on the energy sum. The detection time window is restricted to a front wall reflection and at least a portion of a near-surface dead zone following the front wall reflection.

Systems and methods for a flexible container for transport and storage of a working material are described herein. The material can be a viscous or liquid material when dispensed. The flexible container can be configured to move between a first shape and a second shape. The first shape can allow for efficient transport of the flexible container while the second shape can allow for the flexible container to couple to a dispenser. In certain examples, the flexible container can be cooled for transport and heated for dispensing.

Flexible packaging for temperature sensitive materials

Systems and methods for a container for decreasing the thawing time for a liquid, gel or other fluid material is described herein. The systems can include a container with a body. The body can include a cavity with a dispensing nozzle and a plunger disposed within the cavity. The body can further include one or more channels separate from the cavity. The channel(s) increases the rate of heat transfer associated with the container and, thus, increases the cooling or heating rate of the material within the container.
