Abstract This article proposes the preparation and microwave thermal cured (MTC) epoxy-modified phenolic fibers for first time. Epoxy-modified thermoplastic resin was prepared in acidic condition using phenol, formaldehyde, epichlorohydrin as reactants, then underwent additive reaction with formaldehyde to obtain thermosetting resin, which converted into nascent through wet spinning. Finally, w...

Carbon-phenolic ablators are very efficient heat shields for atmospheric reentry vehicles: they able to protect a capsule from hyper thermal environments characterized by intense fluxes (>1 MW/m2) and high temperature (also exceeding 300°C). Ablative materials can be modified the addition of nano-fillers in order improve their performance: small amounts (in 2–5 wt%) enhance matrix material prop...

This paper describes the carbonization behavior of phenol-formaldehyde resin (PF) blended in the presence of simple organic substances of m-phthalic acid (PA), trimesic acid (TMA) and phloroglucinol (PG). The weight loss and heat flow were monitored in order to study their carbonization behavior by thermogravimetric analysis (TG) and differential scanning calorimetry (DSC), respectively. These ...
