    During the past century, the use of both natural and syn­ thetic polymers has been expanded to include more intricate applications, such as membranes, foams, medicinals, conductors, insulators, fibers, films, packaging and applications requiring high modulus at elevated  › Chemistry › Polymer Science. A novel ultra-high modulus carbon fibre reinforced polymer (CFRP) prestressing tendon made from coal tar pitch-based carbon fibres was characterized in terms of high temperature tensile strength (up to °C) with a series of transient thermal and steady state temperature tensile tests. Digital image correlation was used to capture the high temperature strain development during thermal and

      However, with the development of wireless communications, polyimide films with higher modulus, lower linear thermal expansion coefficient (CTE), lower dielectric constant, higher hygroscopicity are requested to meet the requirement for high-frequency low loss circuit (13, 14, 15). In the portable energy product field, the use of the PI film as The first edition was produced at a time when the advantages of studying oriented polymers were just becoming apparent. From a sci entific stand point it had been demonstrated that greater insight into both structure and properties could be obtained if an oriented polymer was prepared. From a technological viewpoint, major advances were under way, especially in high modulus and high strength ?id.

This book has 14 chapters covering a wide range of fibers from inorganic to synthetic aliphatic, aromatic and cyclic polymeric fibers, and natural fibers that have been written by internationally recognized High modulus polymers book in their respective fields The high-modulus and high-strength fiber has to possess a high molecular orientation and a high crystallinity.

Fortunately, iPP can be easily drawn and crystallized up to fairly high degrees of orientation and crystallinity. The maximum values of Young’s modulus and tensile strength reported up to date are 36–40 GPa and GPa, :// Abstract.

Stress-strain curves often are not straight-line plots, indicating that the modulus is changing with the amount of strain. In this case the initial slope usually is used as the modulus, as is illustrated in the diagram at the right.

Cellular polymers are most important, with flexible polyurethane and urethane–urea copolymers dominating the cushioning foam :// High-modulus polyethylene fibers can be made by solid-state drawing of high-density polyethylene.

These fibers are limited to temperatures of °F or lower. They have good moisture resistance, high impact resistance and attractive electrical properties (i.e., low dielectric constant and low loss tangent).

All polymers will undergo a transition from a glassy to a rubbery state at some temperature. This temperature is the glass transition temperature (T g). It coincides with segmental motion of the polymer chains and a 4–5 order of magnitude reduction in modulus.

Diffusion processes increase by several orders of magnitude on passing through T ://   High Modulus Polymers. DOI link for High Modulus Polymers. High Modulus Polymers book. Approaches to Design and Development. High Modulus Polymers. DOI link for High Modulus Polymers.
