Compendium of fractographic data for composite materials. Interim report, 22 Sep 86-31 Oct 88
The objective of this program is to enhance the capability of the Air Force in conducting failure analysis investigations on composite structure. This interim report builds upon previous efforts in this area as documented in Compendium of Post-Failure Analysis Techniques for Composite Materials, AFWAL-TR-86-4137. This report details the results of the first six tasks which include: (1)identification of techniques for field failure analysts; (2) fractographic techniques other than microscopic examination of the fracture surfaces; (3) a fractographic database of specimens failed under controlled test conditions; (4) a chemical and mechanical property database of constituent and composite materials; (5) data collection format sheets; and, (6) several failure analysis investigations for illustrative purposes. The largest portion of the program was devoted to the fractographic database which includes carbon, fiberglass, kevlar and boron epoxy composites as well as carbon fiber, non-brittle epoxy composites such as carbon/polyetheretherketone (PEEK), carbon/PMR-15, and carbon/multiphase resin (X8551).
