Sizing Extreme Environmental Condition Influences on the Multiphase Polymeric Composites’ CTE

The coefficient of thermal expansion (CTE) of multiphase polymeric composite materials represents an important role in the process of engineered materials design, especially while approaching thermal management issues. Tailoring and designing material combinations in order to develop a composite structure to prove stability over a wide range of temperatures, from cryogenic to high values, to withstand extreme environmental conditions is the dream and the purpose of any engineering team involved in such study/research area. The paper aims to approach and to present the variations of the CTE with extreme environmental conditions (e.g. cryogenic, desert and hygroscopic conditioning) for particular combinations of particle-fibers multiphase polymeric composite materials. Influencing factors will be underlined to accompany the experimental research.
