During Phase I, 3TEX designed universal, one-piece, 3D woven fiber preforms which can be used as either a “Butt” (H) joint or as a “P” joint as needed. Composite joints were fabricated and tested, demonstrating the benefit of the integral nature of the 3D preforms. 3D stress/strain and crack propagation analysis of composite Π-joint was performed using 3D MOSAIC code. 3D displacement, st ...

Military helicopters rotors contend with rain, ice, sand, and flying debris. To prevent damage to the expensive blade protective sheaths or coatings are applied to the leading edge of the rotor blades. A 3-D woven composite sheath with high thermal conductivity fibers running through the thickness can offer the best qualities of both metal sheaths and elastomer coatings. Infused with an elastom ...

Miller Fasteners made from 2-D laminates represent the state of the art in joining CMC panels to metal frames. Despite its success, the extant Miller fastener design is limited by its construction from a laminate of 2-D fabric. The resultant fastener part has poor interlaminar shear strength, and its manufacture and application entails high machining costs and high material scrap rates. 3TEX, i ...

The proposal outlines the use of rapid protyping techniques to create a functional small scale feasibility system and documentation to provide a demonstration of the features needed in a full-scale automated isolation and tag-out system. It will use a highly innovative, patented network control technology that provides a reliable, low cost means to interconnect thousands of remote sensor and cont ...

A simple clamping U bracket to secure itself under pressure on both sides of the aircraft's structural frame ribs. A clamp will be placed on every section where the bonded studs currently exist. A cavity on the bottom of each clamp will hold a stud or other tool to secure the blankets. The outer surface of the bracket will be made of rubber and the inner core will be made of 9255 spring steel, ...

The objective of this proposal is to develop a sizing system for carbon fiber that has the thermal stability to match or exceed that of the matrix resin and be chemically compatible with the fluorinated addition polyimides. More specifically, the sizing will have the same or similar composition to the matrix resin to promote miscibility and interdiffusion and endcapped with phenylethynyl function ...

The USN is seeking innovative solutions to model and aid in the prediction of enemy course of action with emphasis on learning, adaptation, and intent. While analysts and strategists are well-versed in tracking threats against conventional military targets, the new asymmetric threats posed by insurgents and terrorist organizations alike, are much more difficult to anticipate. Given the events and ...

Manning Applied Technology proposes development of the MP-100 handheld FT-infrared photoacoustic chemical agent detector, following a highly successful Phase I effort. Chemical attacks and accidents can be mitigated partially by cost-effective sensors. High priority programs will benefit from a sensor compliant to Joint Warning & Reporting Network (JWARN) standards. The device is ideally suited to ...

The current effort will development and demonstrate a navigation aiding system for autonomous mine neutralization, comprising a disturbance resistent marker and guidance and control sensor for navigation with respect to the marker. The system will low cost to enable use on expendable vehicles, yet provide the range and homing precision dictated by the CONOPS. This Phase 2 effort will include alg ...

We propose investigating new technology for cutting fishing nets, both for commercial fishing or that may be deployed for UUV denial purposes. The envisioned technology is conformal and modular, intended initially for the MRUUV but scalable to larger and smaller vehicles. It is intended as an affordable system requiring minimal space and energy, while providing redundancy in capabilities through ...
