A novel trifunctional epoxy resin 4-(3, 3-dihydro-7-hydroxy-2, 4, 4-trimethyl-2H-1-benzopyran-2-yl)-1, 3-benzenediol glycidyl (shorted as TMBPBTH-EPOXY) was synthesized in our lab to improve thermal performance. Its curing behavior and performance were studied by using 4, 4′-diaminodiphenyl sulfone (DDS) as hardener with the mass ratio of 100:41 of TMBPBTH-EPOXY and DDS. The curing activation e...

The increasing use of composite materials has led to a greater demand for efficient curing cycles to reduce costs and speed up production cycles in manufacturing. One method to achieve this goal is in-line cure monitoring to determine the exact curing time. This article proposes a novel method through which to monitor the curing process inside closed tools by employing ultrasonic spectroscopy. ...

Poly(dimethylsiloxane) (PDMS) microfluidic devices were prepared from different ratios of “curing agent” (which contains silicon hydride groups) to “base” (which contains vinyl-terminated noncross-linked PDMS), to determine the effect of this ratio on electroosmotic flow (EOF). In fabricating devices for this purpose, a novel method for permanently enclosing PDMS channels was developed. As a su...

The standard method of curing industrial coatings has been accomplished by slow open air drying or somewhat faster gas heated convection air ovens. Electric infrared has also been used for curing paints for certain applications. While enhancing the rate of cure, the energy costs become excessive to operate. The introduction of gas fueled infrared catalytic thermoreactors is changing the way ind...

This paper reports the characterization of a photosensitive benzocyclobutene (BCB), a low dielectric constant spin-on polymer for use as interlayer dielectric in the microelectronics industry. Research work is divided into three main sections. First, BCB thin film characterization was done to investigate the effects of curing conditions on BCB film thickness, dielectric properties, optical prop...

This paper describes P–Truck Curing, a Case Based Reasoning system supporting the design of the curing phase for truck tyre production. The design of this process provides a trade–off between an optimal curing degree, to avoid imperfections in the final product, and the reduction of costs, related to thermal energy employed in the curing. Expert curing process designers store information about ...

Different types of curing compounds were applied to lab and field concrete at different times after casting. Two application methods, single and double layer applications, were employed. Concrete properties, such as electrical conductivity, moisture content, sorptivity, degree of hydration, strength, and permeability were evaluated, and the results were employed for assessment of the curing eff...
