The capability to characterize and test advanced composites in simulated operational environments- including elevated temperatures, thermal cycling, moisture, oxidation, solvents, etc. is essential to the future use of these material systems in various civilian and military applications. This program sought funding to establish core facilities for durability assessment of advanced polymer matrix composites in such applications as bridge rehabilitation, high speed civil aircraft, engine components for propulsion, and armored ground vehicles. The cross cutting issue in these programs is the durability of composite materials. The equipment purchased is being used to promote (1) significant advances in the fundamental understanding of degradation mechanisms and (2) concomitant improvements in design and processing aimed at increasing the durability of composite components for these applications. Researchers are currently using the equipment to measure changes in local elasticity over a sample surface. The results obtained thus far show promising correlation between the generated force curve data and the sample moduli. The work has successfully extended the capabilities of the AFM as a probe of nanomechanical properties and property variations important to the performance of composite materials and adhesive. It has also resulted in development of the first experimental technique to directly examine interface regions in multiphase systems.

Advanced polymer matrix composites (PMC) have many advantages such as light weight and high specific strength that make them useful for many aerospace applications. Enormous uncertainty exists, however, in predicting long-term changes in properties of PMCs under extreme environmental conditions, which has limited their use. To help address this issue, the Department of Defense requested a study from the NRC to identify the barriers and limitations to the use of PMCs in extreme environments. The study was to focus on issues surrounding methodologies for predicting long-term performance. This report provides a review of the challenges facing application of PMCs in extreme environments, the current understanding of PMC properties and behavior, an analysis of the importance of data in developing effective models, and recommendations for improving long-term predictive methodologies.

Some years ago in Paisley (Scotland) the International Conference on Composite Materials, headed by Professor I. Marshall, took place. During the conference, I presented a paper on the manufacturing and properties of the Soviet Union's composite materials. Soviet industry had made great achievements in the manufacturing of composite materials for aerospace and rocket applications. For example, the fraction of composites (predominantly carbon fibre reinforced plastics) in the large passenger aircrafts Tu-204 and 11-86 is 12-15% of the structure weight. The percentage by weight share of composites in military aircraft is greater and the fraction of composites (organic fibre reinforced plastics) used in military helicopters exceeds a half of the total structure weight. The nose parts of most rockets are produced in carbon-carbon materials. In the Soviet spacecraft 'Buran' many fuselage tubes are made of boron-aluminium composites. Carbon-aluminium is used for space mirrors and gas turbine blades. These are just a few examples of applications. Many participants at the Paisley conference suggested that the substantial Soviet experience in the field of composite materials should be distilled and presented in the form of a comprehensive reference publication. So the idea of the preparation and publication of a six volume work Soviet Advanced Composites Technology, edited by Academician J. Fridlyander and Professor I. Marshall, was born.
