Synthesis and characterization of an epoxy based thermoset containing a fluorinated thermoplastic
(John Wiley & Sons Inc, 2007-10-01)
A novel fluorinated thermoplastic (FT) was synthesized from diglycidyl ether of bisphenol A (DGEBA), and 3-(trifluoromethyl)aniline. FT was found to be miscible with DGEBA as shown by the existence of a single glass ...
Design of thermosetting polymeric systems based on benzoxazines modified with maleic anhydride
(John Wiley & Sons Inc, 2018-05)
A novel benzoxazine (BzPFA) with carboxylic acid groups in its structure was synthesized in a two-step process. First, BzPOH monomer was obtained from bisphenol A, paraformaldehyde, and ethanolamine with an initial molar ...
Advanced polymer composites in construction

Vegetal fibers in polymeric composites: a review
(Assoc Brasil Polimeros, 2015-01-01)
The need to develop and commercialize materials containing vegetal fibers has grown in order to reduce environmental impact and reach sustainability. Large amounts of lignocellulosic materials are generated around the world ...
Cure cycle analysis in thermoset polymers by thermal and mechanical analysis
(2018-10-31)
A thermoset polymer can be used for specific applications by creating a unique chemical
composition that is designed for certain characteristic environments. To know the behavior of
a thermoset polymer, it is necessary ...
Tannin-phenolic resins: Synthesis, characterization, and application as matrix in biobased composites reinforced with sisal fibers
(ELSEVIER SCI LTDOXFORD, 2013-08-02)
A tannin-phenolic resin (40 wt% of tannin, characterized by H-1 nuclear magnetic resonance (NMR) and C-13 NMR, Fourier transform infrared, thermogravimetry, differential scanning calorimetry) was used to prepare composites ...
Curing kinetics of epoxy / alkyl phosphonium modified nanoclay composites for high performance applications
(Elsevier Science, 2015-04-09)
Alkyl phosphonium salts are novel and unexplored modifiers for polymer based composites which can improve the clays compatibility and dispersion in the polymer matrix. These salts can enhance the thermal stability of the ...
Composites from PMMA modified thermosets and chemically treated woodflour
(John Wiley & Sons Inc, 2003-04-07)
The mechanical behavior of composites made from woodflour and a modified thermoset unsaturated polyester resin has been examined. Polymethylmethacrylate (PMMA), a common low profile additive (LPA), was used as the matrix ...
Kinetic parameter estimation and simulation of pultrusion process of an epoxy-glass fiber system
(Elsevier B.V., 2020-08-01)
Pultrusion is a continuous process for manufacturing polymer composite with uniform cross-sectional profiles. In this process the pulling speed and die temperature are the main process variables that can be used to improve ...
