nterfacial polymerization is a type of step-growth polymerization in which polymerization occurs at an interface between an aqueous solution containing one monomer and an organic solution containing a second monomer. The process was invented by Chemist (later Laboratory Director) Emerson Wittbecker in 1959. American polymer scientists Paul Morgan and Stephanie Kwolek used the term interfacial polycondensation when they studied this method in 1959. The most common polymer made by this method is polyamide, where diamine and diacid chloride reac ....etc

Six-Stroke, High-Efficiency Quasiturbine Concept Engine
With Distinct, Thermally-Insulated
Compression and Expansion Components

George Marchetti and Gilles Saint-Hilaire


Need to increase engine thermal efficiency. This paper presents a Quasiturbine thermal management strategy in the development of high-efficiency engines for the 21st century. In the concept engine, high-octane fuels are preferred because higher engine efficiencies can be attained with these fuels. Higher efficiencies mean less fuel consumption and lower at ....etc

Abstract

The fiber/matrix adhesion is most likely to control the overall mechanical behavior of fiber-reinforced composites. An interfacial reaction may result in various morphological modifications to polymer matrix microstructure in proximity to the fiber surface. The interactions between fiber and polymer matrix during thermal conditioning and thermal shock are important phenomena. Thermal stresses were built-up in glass fiber-reinforced epoxy composites by upthermal shock cycles (negative to positive temperature exposure) for different dur ....etc

Composites materials for aerospace applications
Abstract:
Fibre-reinforced polymer composite materials are fast gaining ground as preferred materials for construction of aircrafts and spacecrafts. In particular, their use as primary structural materials in recent years in several technology-demonstrator front-line aerospace projects world-wide has provided confidence leading to their acceptance as prime materials for aerospace vehicles. This paper gives a review of some of these developments with a discussion of the proble ....etc
