The dieletric relaxation properties of thermosetting material nanocomposites based on spherosilicate nanoplatforms were studied from room temperature to 170 degrees C, varying the frequency from 10 to 1000 KHz. Permittivity ...

Coumarins are used as a natural renewable resource to synthesize coumarin-containing benzoxazine resins. The coumarin-containing benzoxazines are fully characterized in terms of their chemical structure by Fourier-transform ...

High-performance fiber-reinforced thermoset composites processed by additive manufacturing (3D printing) are attracting substantial attention in both academic and industrial fields in a market currently dominated by ...

The thermoplastic and thermoset laminates reinforced with different fibers generate variations in the laminated composite mechanical behavior. This work aims to analyze thermoplastic and thermoset composites creep behavior ...

Polymers are chemical compounds of high molecular weight (on the order 1000-10,000.000), named macromolecule. They are formed by the repetition of a basic unit called mere whose parameter . n is defined by the degree of ...

Composites made from a stryrene/unsaturated polyester thermoset matrix and woodflours from different wood species have been prepared and tested. Pine (Pino Eliottis), eucaliptus (Eucaliptus Saligna) and marmelero (Ruprechia ...

Carbon/epoxy 8552 prepreg is a thermoplastic toughened high-performance epoxy being used in the manufacture of advanced army material. Understanding the cure behavior of a thermosetting system is essential in the development ...

Thermosetting epoxy foams were synthesizedby replacing the commercial synthetic epoxy resin by abiogenic epoxidized vegetable oil. Foam formulations weredeveloped avoiding the use of amine hardeners, organicvolatile compounds ...
