Accelerated ageing of composites [electronic resource] : equipment and experimental protocol design and development / [by] Royale S. Underhill, Neil Chambers, DRDC – Atlantic Research Centre. [Ottawa] : Defence Research and Development Canada, c2016. viii, 32, [3] p. : ill. Scientific report ; 2016-R109 "August 2016." Includes bibliographical references. "Composites have the potential to be lightweight, durable, corrosion- and cavitation-free materials. The technology has been incorporated successfully into aircraft and commercial sea vessels. The Cooperative Research Ships (CRS), Composite Propeller Working Group (COMPROP) is investigating the feasibility of using composites for marine propellers. One aspect of the work is to develop an understanding of how composites age when immersed in seawater for extended periods of time. Ageing can be examined with immersion in real-time, but this is not practical for material screening and selection purposes. One can accelerate ageing by elevating the temperature of the samples, using the principle of time-temperature superposition."--Abstract, p. i.
