“…The previous studies were usually concentrated on the fabricated composite materials, in which slag fibers were generally covered with organic matrix [7][8][9][10][11]. Mechanical properties of the composite materials and filaments have also been researched [12][13][14], which declared that cement with short slag fibers would improve by about 30% in compression and wear resistance.…”

“…Properties of the final ceramic product depend immensely on the polymer type, chemistry, curing temperature, pyrolysis conditions, and processing atmosphere . Černý et al . showed that precursors with O:Si = 1.54 and C:Si = 1.14 had the highest yield (70 wt %); however, only (27 wt %) yield exhibits for resins having O:Si = 2 and C:Si = 4.87 ratios.…”

Nanofibers with several hundred of nanometers were successfully fabricated using electrospinning process and a mixture of two types of polymers which are: polydimethylsiloxane and polyacrylonitrile as precursors. After stabilization and carbonization at 1000 °C, three phases which are: silicon carbide (SiC), carbon, and oxy‐SiC were presented. Spectroscopic and microscopic techniques had confirmed the presence of nanocrystalline SiC and turbostratic carbons. These phases formed an intertwined network at the nanometric scale. In addition, the resulted fibers showed a core‐skin effect with skin richer in carbon and a core mainly dominated by silicon‐based phases in the form SiC or SiOC ceramics. A significant improvement was observed in both tensile strength and elastic modulus in these hybrid fibers. In term of crystallography, these nanofibers seem to exhibit similar microstructure that was observed in Nicalon fiber. However, it was difficult to determine the ratio of these phases and their influence on the physical properties of these hybrid fibers. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.

“…Partially pyrolysed composites, which differ in the technology used, have been investigated in several articles. The influence of pyrolysis temperature on mechanical properties has been investigated for composites reinforced with 1D basalt fibres [19] and 2D woven basalt [20][21][22]. Gadow and Weichand used the H62C resin, an advanced type of solvent-free polysiloxane thermoset from Wacker (Germany), with Kamenny Vek basalt fibres as reinforcement [23][24].…”

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.
