Evaluation of residual iron in carbon nanotubes purified by acid treatments
(Applied Surface Science, 2011-11-01) [Artigo]
A detailed analysis by X-ray photoelectron spectroscopy was carried out on multi-walled carbon nanotube (MWCNT) surfaces after non-oxidative and oxidative purification treatments in liquid-phase. The MWCNT were produced ...
Benzoxazine resin and their nanostructured composites cure kinetic by DSC
(Journal of Materials Research, 2013-11-28) [Artigo]
Benzoxazine resins are a new class of thermosetting phenolic resins that have emerged in recent decades, overcoming the traditional properties of epoxy and phenolic resins applied in the aerospace industry. The incorporation ...
Avaliações térmica e reológica da matriz termoplástica PEKK utilizada em compósitos aeronáuticos
(Polímeros, 2008-09-01) [Artigo]
A matriz termoplástica semicristalina PEKK (poli (éter-cetona-cetona)) tem recebido nos últimos anos uma atenção crescente pelas indústrias aeronáutica e espacial, no processamento de compósitos poliméricos avançados. As ...
Influence of cassava starch content and sintering temperature on the alumina consolidation technique
(Journal of the European Ceramic Society, 2009-06-01) [Artigo]
The influence of starch content and sintering temperature on the preparation of alumina bodies were studied. The process was water-based and cassava starch was used as consolidator, binder and pore former. Colloidal ...
Epoxy Composite with Milimetric Carbon Nanotubes
(Journal of Nanoscience and Nanotechnology, 2011-10-01) [Artigo]
Composite of multi-walled carbon nanotubes (MWCNT) and epoxy resin DGEBA were obtained with DDM hardener. The MWCNT were synthesized with length of millimeters by camphor/ferrocene pyrolysis. Different cure temperatures ...
Avaliação dos parâmetros tempo, corrente e pressão na soldagem por resistência elétrica de compósitos PEI/fibras contínuas: influência na resistência mecânica
(Materia-rio de Janeiro, 2015-04-01) [Artigo]
Nowadays, many components applied in the aerospace industry, which had been previously used with thermoset matrix composites, are being replaced by those with thermoplastic matrix, which is mainly due to having better ...
