Systems for positioning and bonding a nutplate to a substrate having an aperture include a nutplate engagement fixture and a temperature sensor retention fixture. The nutplate engagement fixture includes a rigid tube and an elastomeric tube engaged with the rigid tube, the elastomeric tube having an elongated tube sized to provide a friction fit with the aperture and retain the elastomeric tube within the aperture. The rigid tube is operable to engage the nutplate at one end and the elastomeric tube is configured to anchor the nutplate engagement fixture at the aperture and secure the nutplate in contact with the substrate. The temperature sensor retention fixture includes a fixture body sized and configured to engage with the nutplate and at least one passageway within the fixture body sized and configured to allow a temperature sensor to be inserted or embedded therein with an end proximal a surface of the nutplate.

Bonded nutplate rapid cure system

Embodiments of systems and methods for positioning and bonding a nutplate to a substrate comprising at least one aperture, wherein the system includes a nutplate engagement fixture formed from a rigid tube and an elastomeric tube, a heater operable to deliver heat to a bonding surface of the nutplate, at least one temperature sensor operable to measure the temperature of the bonding surface of the nutplate, a temperature sensor retention fixture operable to position and secure the at least one temperature sensor to the nutplate, and a heater controller operable to control the output from the heater.

A method and associated system for repairing a reinforced polymer-infused fiber composite. The method includes providing a resin infusion device having resin components contained in a flexible, sealed container, positioning a dry fiber reinforcement onto a base layer repair location, providing at least one resin conduit connecting the resin container to a first end of the dry fiber reinforcement, providing at least one vacuum conduit connecting a vacuum source to a second end of the dry fiber reinforcement, covering and sealing the base layer repair location with a vacuum enclosure affixed to the base layer repair location, creating a vacuum environment at the base layer repair location via the vacuum conduit, infusing the dry fiber reinforcement with a reactive mixture of the resin components under vacuum conditions via the resin tubing to form a resin-infused fiber reinforcement, and curing the resin-infused fiber reinforcement inside the vacuum enclosure.

Chemical compositions are provided that include at least one of Formula I or Formula II: where n and m are integers, at least one of Ror Rcomprises an aromatic moiety, and X is selected from the group consisting of CH, NH, O, S, SO, and combinations thereof. Composites formed from the chemical composition and at least one reinforcement material are also provided.

High temperature chemical compositions and composites produced therefrom

A subterranean system including a tunnel network, a plurality of syntactic foam panels, and a wireless communications network is disclosed. The wireless communications network comprises a plurality of wireless transceivers positioned throughout the tunnel network. The wireless communication range defined by communicatively coupled transceivers is a function of signal strength attenuation in a wireless signal traveling between the communicatively coupled transceivers. The tunnel network comprises tunnel support structure that contributes to the signal strength attenuation and a plurality of support apertures formed in the tunnel support structure. The syntactic foam panels are secured to the tunnel support structure to cover at least some of the support apertures and the composition and configuration of the syntactic foam panels are such that the panels do not make a significant contribution to the signal strength attenuation between communicatively coupled transceivers.

A method of repairing a composite component having a damaged area including: laying a composite patch over the damaged area; activating the shape memory polymer resin to easily and quickly mold said patch to said damaged area; deactivating said shape memory polymer so that said composite patch retains the molded shape; and bonding said composite patch to said damaged part.

Method of making and using shape memory polymer composite patches

The present invention utilizes the unique shape recovery properties of shape memory materials, especially shape memory polymers, to provide an inexpensive and easily identified method of determining when a product has been exposed to environmental conditions that would make it likely that the product has expired or is unfit for use. By allowing the shape memory material to alter its shape from a deformed shape to a memory shape in response to exposure to environmental conditions while attached to a visual indication device a viewer can easily determine if a product has expired.

Patches consisting of transparent or translucent shape memory material can be manufactured so as to affect repair of transparent or translucent parts that have been damaged. These patches can be used to cover cracks and holes or provide additional structural support for the damaged parts. The patches can vary greatly in size and properties depending on the desired application.

Method of making and using shape memory polymer patches

A method of fabricating and using a removable, inflatable mandrel of shape memory polymer for use in manufacturing composite parts including the steps of providing a processed pre-form of shape memory polymer, replicating a mold with the shape memory polymer, using the mold as a mandrel in the creation of composite parts, and removing the shape memory mandrel quickly and easily from the part without damage to the finished part.

Method of using a shape memory material as a mandrel for composite part manufacturing

The methods of manufacturing molds from shape memory materials and molds made thereby, in accordance with the present invention, provide numerous advantages for molding castable composite parts. The initial mold cost is low enough to accommodate economical production of as few as a single part incorporating high surface definition and intricate three dimensional detail. The preferred methods and molds made thereby are transparent, thereby, curing of the corresponding part by ultra-violet and infra-red light is made possible, as well as, visual inspection during injection and curing of the given resin. Removal of the cured part from within the mold is simplified.

Structural and optical applications for shape memory polymers (SMP)

A shape memory polymer contact lens mold is formed from a sheet of a shape memory polymer in a press, an agile tool or by an agile tool formed by an inert gas at a temperature at or above the glass transition temperature which is thereupon cooled to below the glass transition temperature and removed therefrom.
