Failure Analysis of Composite Structure Materials.

Abstract

The objectives of the Failure Analysis for Composite Structural Materials program are to develop analytical and diagnostic techniques that can be used for determining the causes of failure in composite materials and to incorporate these results into a compendium of procedures that may be used as a reference manual when conducting a postfailure analysis of a composite structure, given the failed part as the starting point of the investigation. Such techniques include flowcharts describing the logical arrangement of investigative operations along with diagnostic procedures that reveal the cause and mechanism of failure. To achieve these objectives, this program was divided into five tasks: (1) task 1-literature search and diagnostic technique selection, (2) task 2-specimen production and test, (3) task 3-diagnostic technique evaluations, (4) task 4-creation of a failure analysis compendium, and (5) task 5-evaluation and demonstration of techniques. This final report summarizes the progress and findings of activities carried out for tasks 1 through 5 that identified, organized, and examined a variety of postfailure analysis methods for composite materials. Because such failures may arise from a wide variety of causes, analysis techniques examined included four basic disciplines: nondestructive evaluation (NDE), stress analysis, fractography, and materials characterization.
