Thermal degradation of a phenolic resin, vegetable fibers, and derived composites
(John Wiley & Sons Inc, 2008-03)
The thermal degradation behavior of resol, several vegetable fibers (two types of cotton fibers, sisal and sugar cane bagasse) and derived polymer composites have been investigated using thermogravimetric analysis (TGA). ...
Estimation of mechanical property degradation of poly(lactic acid) and flax fibre reinforced poly(lactic acid) bio-composites during thermal processing
(Elsevier, 2018-02)
Thermal degradation and chemical degradation are among the key issues affecting mechanical properties and ultimately utilization of natural fibre reinforced polymer (NFRP) bio-composites. In our previous work, mathematical ...
Influence of mechanical and chemical degradation in the surface roughness, gloss, and color of microhybrid composites
(2017-01-01)
Aim: The aim of this study was to investigate the association of different degradations on the roughness, gloss, and color changes of microhybrid composites. Materials and methods: Ten specimens were prepared for Charisma, ...
Influence of chemical degradation and toothbrushing on surface of composites
(2015-07-16)
Objective: The aim of this study was to evaluate the effect of chemical degradation media associated with brushing on surface roughness (Ra) and Knoop microhardness (KHN) analyses of different composites. Materials and ...
Modified woodflour as thermoset fillers II: Thermal degradation of woodflours and composites
(Elsevier Science, 2001-05)
Composites made from an unsaturated polyester/styrene thermoset matrix and maleic anhydride esterified woodflour have been prepared and tested. Different degrees of esterification of the wood particles with maleic anhydride ...

Environmental effects on viscoelastic behavior of carbon fiber/PEKK thermoplastic composites
(Sage Publications Ltd, 2014-04-01)
In the last years, thermoplastic composites have been introduced as structural materials for high performance aerospace applications. However, these materials can present problems when exposed to moisture, temperature, and ...
SnO(2)-based materials for pesticide degradation
(ELSEVIER SCIENCE BV, 2010)
This study presents the results of the degradation of the pesticide atrazine using electrochemical and photo-assisted electrochemical degradation techniques using SnO(2)-containing electrode of nominal composition electrodes ...
Impact energy absorption capability of thermoplastic commingled composites
(2019-11-01)
The energy absorption capability of structural thermoplastic composites is governed by the matrix thermal degradation kinetics. This study focuses on the development of a multiple regression model to predict the impact ...
