Mechanical properties of reactively flame retarded cyanate ester/epoxy resin blends and their carbon fibre reinforced composites

open access: yeseXPRESS Polymer Letters, 2016
Cyanate ester/epoxy resin (CE/EP) carbon fibre reinforced composites consisting of diglycidyl ether of bisphenol A (DGEBA) and novolac type cyanate ester (CE) were prepared and reactively flame retarded using epoxy functional adduct of DGEBA and 9,10 ...

Laser treatment of high-performance Kynol fibers: An example as alternative tool for coloration and imaging on surfaces of high-performance fibers [PDF]

open access: yesTekstilna industrija, 2020
Novolac resins are used to prepare high-performance flame-retardant fibers, which are also supplied under the brand name Kynol fibers. In the current study, Kynol fiber materials are treated with a laser beam to introduce dark coloration at distinct ...

SiC synthesis using domestic mineral resources [PDF]

open access: yesProcessing and Application of Ceramics, 2011
The possibility of using domestic Mg-silicate (sepiolite, white) as Si source and novolac resin (as carbon source), for synthesis of fine β-SiC powder at relatively low temperatures (1673−1873 K), was demonstrated.

Characterization of a novolac resin substituting phenol by ammonium lignosulfonate as filler or extender

open access: yesBioResources, 2007
In this work two types of lignin-novolac resins have been formulated, partially substituting phenol by softwood ammonium lignosulfonate as filler or extender (methylolated) to study the viability of that substitution when resins will be employed as ...

Mechanisms of promoted β-SiC crystallisation in pyrolyzed phenylformaldehyde/methylphenylsiloxane composites

open access: yesOpen Ceramics
An innovative approach to obtaining a β-SiC matrix using methylphenylsiloxane and phenylformaldehyde resins was proposed. Thermogravimetric runs up to 1500 °C reveal a two- or three-stage process involving the decomposition and recombination, depending ...

Revestimentos de alta camada obtidos com a modificação de resinas epóxi novolaca pela reação com organo-siloxano e catálise ácida

open access: yesQuímica Nova
Epoxy resins are an important class of thermostable polymers, widely used in structural applications or as adhesives. However, the low fracture resistance is their main weakness in many applications.
