  1. 3-D nondestructive imaging techniques for mesoscale damage analysis of composite materials

    SBC: L J ENGINEERING TECHNOLOGY            Topic: AF11BT04

    ABSTRACT: The main issue with the development of a reliable constitutive model for explosive materials and concretes is the lack of a fundamental understanding of the evolution of 3-D microstructure and damage in these materials when they are subjected to multi-axial loading under confinement conditions. The main technical challenges are determining the 3-D microstructure and damage evolution pro ...

  2. 3D nondestructive imaging techniques for mesoscale damage analysis of composite materials

    SBC: Nextgen Aeronautics, Inc.            Topic: AF11BT04

    ABSTRACT: Energetic materials may be subjected to severe environments of pressure and shear loading, causing damage that leads to premature initiation or suboptimal performance. This damage is at the mesoscale, at and below the grain size of the particles, in the range of 5-400 microns. X-ray computed microtomography is a 3D non-destructive technique that can be used for imaging this damage. It e ...

  3. A High Resolution Evanescent Wave Velocity Sensor for Liquid and Gas Flow in Microfluidics

    SBC: VIOSENSE CORP.            Topic: AF04T024

    This project proposes to design and build an advanced evanescent velocity sensor for near wall velocity measurements in microfluidic devices. Optical MEMS technology will be utilized to create a compact sensor design. The sensor will measure velocities within 100 nm of the channel wall, which is five times closer than the best current technique. The sensor will have a spatial resolution of 100 nm ...

  4. A Multiphysics Framework Utilizing Nonlinear Material Models for Predicting Impact of Structural Profile Disruption on High-Velocity Air Vehicles

    SBC: ATA Engineering, Inc.            Topic: AF17AT025

    The aerothermal environment for hypersonic flight vehicles is severe and can generate extremely high material temperatures. These high-temperature environments can cause intense localized heating, which may result in local pockets and/or structural instabilities, especially at vehicle leading-edge regions, and may lead to disruptions that affect vehicle performance. The aerothermal environment may ...

  6. A Novel Process of CNTs/Al2O3 Hybrid Ceramics

    SBC: Chemat Technology, Inc.            Topic: AF05T023

    Carbon nanotubes possess extraordinary mechanical, thermal and electrical properties. Attempts have been made to develop advanced engineering materials with improved or novel properties through the incorporation of carbon nanotubes in selected matrices (polymers, metals and ceramics). Recently, the use of carbon nanotubes to reinforce ceramic composites has made exciting progress. However, oxida ...

  7. A room temperature tunable antenna coupled intersubband terahertz (TACIT) detector for man-portable spectroscopy instruments

    SBC: Tanner Research, Inc.            Topic: AF08BT26

    Several emerging applications require chemical fingerprinting of hidden/concealed objects (via THz spectroscopy) from man-portable or UAV platforms.  While the field of THz detectors has largely been driven by the needs of the astrophysics community, where cryocooling is considered acceptable, recently, two classes of room temperature THz detectors were demonstrated.   One of these is the tunab ...

  8. A Unique Focal Plane Array Detector for THz and MM Wave Imaging

    SBC: Intelligent Optical Systems, Inc.            Topic: AF09BT33

    Detecting explosives and weapons under clothing or in hand carried packages, and imaging terrain and objects through fog and smoke are two high-priority needs that can be met using light in the Terahertz frequency range. However, to image concealed threats, and aid in navigation in fog and smoke, a practical, low cost THz camera is needed. Intelligent Optical Systems (IOS) in collaboration with Re ...
