Microwave-cured tracheostoma vents

The Journal of Prosthetic Dentistry, 1992
This article describes a technique of making custom flexible and combined flexible/rigid tracheostoma vents. The combined flexible rigid tracheostoma vent provides a flexible material that is nonirritating in the peristomial region and maintains a patent tracheostoma by the rigidity of the hard acrylic resin section.

Microwave Curing of Composites

Journal of Composite Materials, 1984
A model was developed which describes the microwave curing process of continuous fiber reinforced organic matrix composites. On the basis of the model, a computer code was developed which provides the temperature distribution, the resin viscosity, the degree of cure of the resin, and the resin contents of the composite and the bleeder during microwave

Epoxy nanocomposites curing by microwaves

Polymer Engineering & Science, 2006
Abstract In this work, chemically modified sodium montmorillonite and epoxy monomer were used to prepare nanocomposites in two consecutive stages. In the first stage, dodecylamine, octadecylamine, hexadecylamine, and hexadecyltrimethyl ammonium bromide were used to prepare various organophilic clays. In the second stage, the bisphenol‐

Microwave curing cement-fly ash blended paste

Construction and Building Materials, 2021
Abstract The embodied carbon dioxide (ECO2) of Portland cement (PC) is about 850 kg/t and consequently the global cement manufacture accounts for 7–9% of the CO2 produced by mankind annually. On the other hand, the ECO2 of fly ash (FA) is only 0.1 kg/t.

Practical microwave curing studies for undergraduates

Polymer International, 1999
Microwave curing has recently generated interest as an alternative to the conventional thermal curing of polymers. Advantages of the microwave process over the thermal method include faster curing times, improved efficiency of curing, and enhanced properties of the polymers. This paper describes an undergraduate polymer chemistry experiment utilizing a

Interfacial properties of microwave cured composites

Composites, 1995
A unidirectional continuous E-glass fibre/epoxy composite was cured using microwaves. The mechanical behaviour of the composite was studied by in situ transverse tensile and short-beam bending tests. The mechanisms of rupture were analysed. By comparing microwave cured composites (MCCs) with thermal cured composites (TCCs), it was found that more voids
