An investigation of two different intumescent coatings used in steel fire protection has been performed to evaluate their efficiency. A set of experimental tests is presented. They were conducted in a cone calorimeter, considering different thicknesses an... see more

Animal protein-based fibers used in textiles often are assumed to have uniform properties independent of source, and yet are different when considering texture, structure, and color. Differences between fibers from animal species have been studied in rega... see more

The thermal barrier efficiency of two types of ceramic particle, glass flakes and aluminum titanate, dispersed on the surface of carbon-fiber epoxy composites, has been evaluated using a cone calorimeter at 35 and 50 kW/m2, in addition to temperature grad... see more

Ammonium polyphosphate–diatomite composite filler (APP-diatomite composite filler) was modified with silane coupling agent KH550 to improve the flame retardancy of filled paper. Cone calorimeter was used to analyze the heat and smoke releasing rates, as w... see more

The efficiency of using intumescent flame retardants in polyurethane coatings based on tall oil fatty acids esters was assessed. The influence of the content of each of the flame retardants (ammonium polyphosphate, melamine and pentaerythriol) separately ... see more

A series of polyurethane-polyisocyanurate (PU-PIR) foams synthesized from PET-waste-derived aromatic polyester polyols (APP) was studied using thermogravimetric analysis, Cone calorimeter and burning tests. The effect of chemical structure of the APP cont... see more

The aim of this work was to investigate the effect of phosphorus-based additive and reactive flame retardants (FR) on the flammability and mechanical properties of a pentaerythritol-based model epoxy resin system cured with a cycloaliphatic diamine harden... see more

Considerando a necessidade de criar possibilidades de se continuar as atividades pedagógicas no período pandêmico, foi instaurado o Ensino Remoto Emergencial (ERE), empregando as diferentes tecnologias digitais presentes hoje em nossa sociedade. A motivaç... see more

As últimas décadas do século XVIII sofreram modificações políticas e culturais que influenciaram o aumento do número de músicos militares em escala global. Dentre essas modificações, destacam-se a valorização dos regimentos do Exército como integrantes da... see more
