Polysiloxanes polymer coatings were formed on carbon fiber‐reinforced silicon carbide (C/SiC) composites at 100°C in air with barium–strontium aluminosilicate (BSAS) as fillers. After the polymeric coatings were pyrolyzed at 1350°C under argon, a dense SiOC–BSAS‐coated C/SiC composite was obtained. The oxidation test in dry air and the corrosion test in water vapor were carried out on the coated composites at 1250°C, respectively. The results indicated that the polymer‐derived SiOC–BSAS coatings could protect the C/SiC composites well both in dry air and water vapor. Even after corroded for 200 h in water vapor, the coated C/SiC composites showed little weight loss and high residual flexural strength.

“…For all the composite materials studied, the same matrix precursor i.e., polymethylsiloxane resin Lukosil M130 (Lučební závody a.s., Czechia) was used. This resin was used for the production of pyrolysed composites or studied with this intent in previous works [27][28][29][30]. A great advantage of this resin is its low weight loss during pyrolysis.…”

The study considers the mechanical properties and temperature resistance of partially pyrolysed composites reinforced with various fibres. The composites were prepared by pyrolysis at 650 °C, where only partial conversion of the polymer to the inorganic SiOC structure takes place in the matrix. Such a hybrid matrix bears resemblance to polymeric materials in a density and Young's modulus, but oxidation resistance and creep behaviour are closer to silicate glasses. Pyrolysis also ensures that the whole composite material is non-flammable with very low potential for releasing toxic gases during a fire. Three types of glass fibres (E-glass, R-glass, E-CR-glass fibres), two types of basalt fibres, and two types of high-strength (HS) carbon fibres were used as reinforcements. The mechanical properties-Young's and shear moduli, flexural strength, and fracture toughness-were measured at room temperature. Thermogravimetric measurements and creep tests of these composites allowed estimation of their temperature resistance and fire resistance. The results obtained suggest that the materials under investigation can be applied as panels or shells in the building industry and in transportation facilities.
