This book was released on 1965 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relationship between cohesive energy (c.e.) or cohesive energy density (c.e.d.) and the glass transition temperature T sub G of polymers was re-examined on the basis of literature data. For polymers with T sub G's above 25 C there is no correlation between published or calculated values of c.e. or c.e.d. and T sub G. However, for the rest of the polymers there is a linear relationship between c.e.d. and T sub G, and a broad relationship between c.e. and T sub G. These results imply that c.e.d. is the regulating, though not the only, factor in determining T sub G's up to values of approximately 25 C. (Author).

Download or read book A Study of Cohesive Forces Refractive Indices and Glass Transition Temperature Data of Polymers written by J. H. Sewell and published by . This book was released on 1966 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a linear relationship between the molar refraction, R, and the sum of the molar-attraction constants, (sq. rt. of (EV)), both for liquids and polymers. It follows that cohesive energy density, E/V, is directly proportional to the refractive index function, (n sq. - 1/n sq. + 2)sq. It is shown and found that for two non-polar rubbers, swelling tends to increase as the refractive index of a solvent approaches that of a rubber, but maximum swelling occurs at a lower refractive index than predicted. As expected, swelling data for polar rubbers and solvents do not follow the predicted trend. No relationship is found between glass temperature (TG) and refractive index for polymers having TG's below 298K because of divergences in data from relationships involving cohesive energy density and TG and between R and (sq. rt. of (EV)).

Available in PDF, EPUB and Kindle. Book excerpt: 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.
