Adição de resíduo termofixo em matriz de polipropileno reciclado: análise de propriedades térmicas e mecânicas.
(Universidade Federal de São CarlosUFSCarPrograma de Pós-graduação em Ciências dos Materiais (campus SOROCABA)Câmpus Sorocaba, 2017-12-15)
The proper disposal of solid waste has driven studies to enable the use of recycled materials and waste. So, in this work were molded composites using raw materials from industrial waste and evaluated several mechanical ...
Relationships between the curing conditions and some mechanical properties of hybrid thermosetting materials
The relationship between the heat of polymerization (ΔH) and activation energy (Ea) parameters, obtained by differential scanning calorimetry (DSC) and the ratio of epoxy resin to hardener of the thermosetting materials ...
Vinyl ester resin modified with silicone-based additives: II. Flammability properties
(John Wiley & Sons IncHobokenEUA, 2006)
Thermoset matrix reinforced with sisal fibers: Effect of the cure cycle on the properties of the biobased composite
(ELSEVIER SCI LTD, 2009)
Thermoset phenolic composites reinforced with sisal fibers were prepared to optimize the cure step. In the present study, processing parameters such as pressure, temperature, and time interval were varied to control the ...
LYOCELL AND COTTON FIBERS AS REINFORCEMENTS FOR A THERMOSET POLYMER
(NORTH CAROLINA STATE UNIV DEPT WOOD & PAPER SCIRALEIGH, 2012)
Cellulose fibers obtained from the textile industry (lyocell) were investigated as a potential reinforcement for thermoset phenolic matrices, to improve their mechanical properties. Textile cotton fibers were also considered. ...
Cardanol-based thermoset plastic reinforced by sponge gourd fibers (Luffa cylindrica)
A growing global trend for maximum use of natural resources through new processes and products has enhanced studies and exploration of renewable natural materials. In this study, cardanol, a component of the cashew nut ...
Resin–Sisal and Wood Flour Composites Made from Unsaturated Polyester Thermosets
Short fibers and wood flour were selected as fillers in the production of two types of unsaturated polyester composites (bisphenolic and isophthalic-based thermosets). Sisal fibers were subjected to washing in order to ...
Modified woodflour as thermoset fillers Part I. Effect of the chemical modification and percentage of filler on the mechanical properties
Composites made from an unsaturated polyester/styrene thermoset matrix and esterified woodflour have been prepared and tested. Different degrees of esterification of the wood particles with maleic anhydride were obtained ...
Quasi-isothermal DSC testing of epoxy adhesives using initial fast heating rates
Three major factors decrease the accuracy of the cure measurement in standard-isothermal testing using differential scanning calorimetry (DSC). First, cure occurs during the heating step. Second, data are lost during the ...
