Summary A linear relationship between water activity (aW) in moist salted fish products and NaCl molality was found: (aW) SF = 1.002–0.042 m; where m is the NaCl molality considering it to be in true solution in the total water content of the produ

The modification of an amine-cured epoxy resin by the addition of polyurethanes (PU) was investigated, and their mechanical and impact properties were related to their microstructure and morphology. For the study, two different PU were selected: a co

The curing process of an epoxy-urethane copolymer in a heated mold was studied. The epoxy resin (DGEBA, Araldyt GY9527; Ciba Geigy), was coreacted with a urethane prepolymer (PU, Desmocap 12; Bayer) through an amine that acted as crosslinking agent (

An urethane–acrylic resin for a pultrusion processing application was studied. The concentration of Perkadox 16 and methyl methacrylate (MMA) was changed in the formulation mixture. A calorimetric study was performed in a DSC equipment. Isothermal

Amine-cured epoxy resins were modified to improve their impact properties. Urethane prepolymers (PUs), in which terminal isocyanate groups were blocked with nonylphenol (NP) for easy handling, were used as modifiers. The synthesis of the elastomers w

The flexural properties of glass-fiber epoxy unidirectional composites have been studied as the surface of the glass fiber is changed. The glass fibers were treated with two different coatings: a mono-epoxy and a di-epoxy. Both were deposited on the

Pultrusion processing for epoxy resin with glass, carbon, and DuPont Kevlar fibers has been modeled. The model has three submodels: heat transfer, pressure, and force. The validity of the model was verified by comparison of results obtained on the gl

To use a resin for a composite, the processing conditions must be known. An engineering analysis through numerical simulation of the heat mold cure is useful for this purpose. The chemical systems studied were based in furfuryl alcohol (FA) and furfu

The mechanical properties of a system consisting of a bisphenol A diglycidylether (DGEBA) expoxy, cured with a cycloaliphatic diamine (4,4′-diamino-3,3 dimethyldicyclohexyl-methane, 3DCM), in the presence of an epoxy-terminated butadiene-acrylonitr
