Examination of commercial ceramic coatings for the electrical insulation of Bi-2212 wire

Andrea Testino, Davide Uglietti, Robert Sobota

In the last twenty years, a number of studies have been dedicated to the development of thin ceramic coating for the electrical insulation of Ag-sheathed Bi-2212 wires. Instead of preparing a coating by mixing different compounds in house, this technical n ...

Incorporation of Lignin in Bio-Based Resins for Potential Application in Fiber-Polymer Composites

Mateus De Assunção Hofmann

Bio-based resins, obtained from renewable raw materials, are a more sustainable alternative to oil-based resins for fiber-reinforced polymer (FRP) composites. The incorporation of lignin in those resins has the potential to enhance their performance. This ...

3D spacers enhance flow kinetics in resin transfer molding with woven fabrics

Véronique Michaud, Baris Çaglar, Damiano Salvatori

Impregnation time in Resin Transfer Molding (RTM) is directly proportional to resin viscosity and inversely proportional to fabric permeability, limiting the use of high-viscosity resins with conventional reinforcements. In this study, we show how to reduc ...

Functional, Hyperbranched Polyesters Via Baylis-Hillman Polymerization

Harm-Anton Klok, Frederik Roman Wurm, Sanhao Ji

Hyperbranched polyesters are among the most common hyperbranched polymers. One of the interesting features of hyperbranched polyesters is that they contain unreacted hydroxyl and carboxylic acid groups at the linear and terminal structural units, which can ...

Material and structural performance of fiber-reinforced polymer composites at elevated and high temperatures

Yu Bai

As the range of applications for fiber-reinforced polymer (FRP) composite materials in civil engineering constantly increases, there is more and more concern with regard to their performance in critical environments. The fire behavior of composite material ...

Through thickness air permeability of prepregs during cure

Jan-Anders Edvin Maansson, Véronique Michaud

An experimental method based on a falling pressure measurement is proposed to evaluate the through thickness air permeability of prepregs during cure, with two set-up variants. One concerns the measurement of the inherent air permeability and the other app ...

Wettability of Glass Fibers in Reactive Thermoplastic/Polyester Blends: Comparison between Compatible and Incompatible Thermoplastics

Jan-Anders Edvin Maansson, Véronique Michaud, Xavier Bulliard

The evolution of morphology of reactive thermoplastic/unsaturated polyester blends at the surface of glass fibers is investigated during curing. The study focuses on two different types of thermoplastics, incompatible and compatible respectively with the p ...
