Fire-Resistance of Thermal Silica-Based Geopolymer Carbon Composite
Original language description
Thermal silica-based geopolymer composites reinforced by approximately 45 vol.% of unidirectional carbon HTS 56311600tex 24Kfibers were synthesized andfabricated at optimal range of curing conditions, the ejfects of thermal exposure in aforced airfurnaceat high temperatures up to 1000 °C for 1 hour on the thermal-mechanical properties ofthe geocomposites were studied. The flexural properties of the resulting composites were determined on a universal testing machine under three-point bending mode in accordance with ASTM C 1341-06 and the results show that the mechanical properties of geocomposite retained nearly 50 to 60%, after thermal exposure up to 1000 °C, in comparison with these of the geocomposite tested at 20 °C. The microstructure of the geocomposites was analyzed by means ofScanning Electron Microscope (SEM) after calcination, at temperature higher than 800 °C the microstructure of geocomposite looks like foamed composites and the adhesion between the fiber and matrix still s
