In composites, not only can properties vary with load direction, fiber based composites also offer the unique ability to tailor material properties locally. Localized matrix or fiber architecture changes can meet local mechanical, electrical, or thermal loads within a component or vehicle, without weight penalty or resort to additional external structures. In Phase I, the team used 3TEX 3-D wea ...

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 ...

Strength and durability of commonly used bonded and bolted composite-to-composite and composite-to-metal structural joints suffer from sharp geometry variations, mismatch of elastic moduli, Poisson’s ratios, coefficients of thermal expansion and thermal conductivity of the adherends, altogether causing high stress concentration and premature joint failure. The proposed work is focused on develop ...

We propose to continue the development and characterization of a polymeric nanoencapsulation technology that can increase the lifetime of a protein therapeutic agent within a biological system. The materials have been demonstrated to exhibit no cytotoxicity and to efficiently deliver antibody against Protective Antigen of bacillus anthracis.

The goal of this proposal is to find novel combinations of approved drugs for the treatment and/or prevention of infection with filoviruses. Ebola and Marburg viruses, the only filoviruses, cause an acute hemorrhagic fever syndrome which has a high mortality rate and poses a significant bio-terrorism threat. There are currently no therapeutic agents available to treat filovirus infections and the ...

We propose to develop a computer based system for the online analysis of bio-behavioral signals associated with momentary loss of alertness. We will continue our development of bio-behavioral measures indicative of lapses in alertness. Our system will use only measures that can be obtained without attaching sensors to the operator. We will concentrate on monitoring the oculomotor system using came ...

Software development organizations are faced with developing and verifying required system software capability, functionality, performance, reliability, and safety, while at the same time meeting tight budget and schedule constraints. Due to software complexity, many programs experience mission critical failures and incur schedule delays and cost overruns. The Army and other organizations, there ...

In this PhaseII SBIR effort, Corvid Technologies completes the development of an innovative approach for solving Unstructured Fixed Grid Navier-Stokes CFD flow simulations. The proposed approach developed at Corvid is referred to as the Virtual Geometry Insertion (VGI) technique. This approach allows for the virtual insertion of arbitrary geometric components into a standard CFD analysis. This g ...

The objective of this proposal is to improve the computational tools identified in Phase 1 that will be useful in assessing rocket and missile propulsion systems for compliance with insensitive munitions (IM) requirements. Comprehensive testing to ascertain IM compliance for such systems is time-consuming and expensive. High-fidelity computational tools exist that can be used to address the asse ...
