Dynamic Elastic Modulus and Internal Friction in Fibrous Compositeserived from fundamental interatomic forces, elastic constants index both cohesion and strength. They relate to other physical properties such as specific heat and thermal expansion, all of which help define a solid’s equation of state.

Spectroscopic Analysis of High Polymers for Use at Low Temperaturesighly desirable to develop methods of checking quickly and simply if a certain polymer can be used at low temperatures or not. In this paper, we propose the use of spectroscopy as a testing procedure. From simple considerations of the molecular structure of polymers, it appears that spectroscopy in

Variation of Dielectric Microwave Losses in Polyethylene as the Result of Different Sample Treatment connection with the development of superconducting communication cables.. The feasibility of superconductive coaxial cables as a communication medium with an enormous capacity may be increased by applying superconducting materials with critical temperatures above 20 K using liquid hydrogen as a coo

Fracture Properties of Epoxy Resins at Low Temperaturesthe conductor and to insure the accuracy of the field. Therefore, in cryogenic engineering, it is very important to know the low-temperature properties of the materials. Examples are: dilatation, moduli of elasticity, and shear. In this paper, the stress intensity factor, the fracture toughness, and
