Lightweight multiscale hybrid carbon-quartz fiber fabric reinforced phenolic-silica aerogel nanocomposite for high temperature thermal protection
TL;DR: In this paper, a novel lightweight hybrid carbon-quartz fiber fabric reinforced phenolic-silica (C-QF/PSi) aerogel nanocomposite was fabricated through impregnation using CQF hybrid needled felt as three-dimensional reinforcement and PSi hybrid aerogels as matrix.

Mechanisms of the pyrolysis of phenolic resin in a carbon/phenolic composite
Kimberly A. Trick,Tony E. Saliba +1 more
TL;DR: In this paper, a mechanism for the pyrolysis of carbon/phenolic composites is proposed, which describes the resin reaction as occurring in three major reaction regions: formation of additional crosslinks, breaking of the crosslinks and stripping of the aromatic rings.
