The overall objective of this project was to develop a Low Volatile Organic Compound (VOC) Chemical Agent Resistant Coating (CARC) system for use on Army, Marine Crops, and Air Force systems suitable for use on military equipment by services in which the materials and processes for the reformulation, application, stripping and disposal are optimized and in compliance with current requirements.

Southwest Research Institute, acting on behalf of the Air Force Coating Technology Integration Office (CTIO), has completed a test program assessing dry media blast (DMB) selective stripping of a coating system originally developed to work well with high-pressure water blast stripping. The goal was to determine any feasibility of using a DMB process for selective stripping of the topcoat from the coating system containing the barrier coating.

The final technical report on holographic testing research includes a number of specific investigations conducted at the Radar and Optics Division of Willow Run Laboratories and at Cooley Electronics Laboratory of The University of Michigan. The investigations described include the following: (1) interferometric detection of microcracks; (2) detection of debonds in honeycomb sandwich structures, (3) real-time monitoring of stress-corrosion cracking, (4) interferometry of three-dimensional, refractive-index fields, (5) measurement of vibrational amplitudes, (6) holographic contouring, (7) optical determination of rms surface roughness, and (8) non-destructive inspection of shell casings and projectiles. The report also includes a brief introductory section on holography and holographic interferometry and a brief glossary of technical terms for the benefit of readers who are not acquainted with this technique.
