摘要

The main goal of this article is to present the pultrusion process for glass fiber- and carbon fiber-reinforced chemically bonded phosphate ceramics (CBPCs). Samples were fabricated with 15% of fibers by volume. An improvement (with respect to the matrix) of 29 times for the bending strength of CBPCs pultruded graphite fibers composites and 17 times for CBPCs pultruded glass fiber composites is shown. Bending strength was obtained with the three-point bending test. The CBPCs were fabricated by mixing special formulations of both wollastonite powder and phosphoric acid, through resonant acoustic mixing. The microstructure was analyzed with optical and scanning electron microscopes. X-ray compositional maps were obtained for the cross-section of pultruded samples with SEM-EDS. Pultruded sample response at high temperature and thermal shock were also analyzed. The structural characterization of samples was conducted by using X-ray micro tomography.
