Aleshkevich, V. V. published the artcileC/C composites developed from phthalonitrile based composites, Recommanded Product: Phthalonitrile, the main research area is carbon fabric phthalonitrile composite reinforced plastic porosity.
Carbonization of carbon fabric reinforced plastics (CFRPs) with phthalonitrile matrixes at 1000°C was investigated. Four different carbonization modes were tested. It was explored, that a mode with step heat rate is most beneficial. Two different phthalonitrile resins were investigated. Elemental anal. of final carbon-carbon composite (C/C) matrix was carried out and the results showed up to 88.5 mass% carbon presence. Final C/C d. reached 1.5991 after only one cycle of impregnation-carbonization. Final porosity of samples reached 9.2%. These results allow to consider phthalonitriles as a prospective carbon precursor for C/Cs manufacturing Mech. testing of the C/C samples was performed (Compressive strength P = 72.2MPa, E = 11.8 GPa). Tribol. data was received (coefficient of friction = 0.31, wear rate = 30μ/min). Thermal anal. was carried out (χ = 72.94 W/m*K, α = 85.8 cm2/s).
IOP Conference Series: Materials Science and Engineering published new progress about Carbonization. 91-15-6 belongs to class nitriles-buliding-blocks, name is Phthalonitrile, and the molecular formula is C8H4N2, Recommanded Product: Phthalonitrile.
