PULTRUDED COMPOSITES WITH A NOVEL CERAMIC RESIN MATRIX EXPOSED TO TEMPERATURES UP TO 1000C

摘要

Traditionally the processing of ceramics involves high temperatures, thereby contributingrnsignificantly to global warming. This paper presents the science and manufacturing ofrnchemically bonded phosphate ceramic resin and its composites. The materials are exposed to airrnin a temperature range of 200C to 1000C. CBPC (Chemically Bonded Phosphate Composite)rnmanufacturing can be performed at room temperature without requiring further thermalrntreatment. The ceramics were produced by mixing a phosphoric acid formulation withrnwollastonite powder and fly ash. Glass, basalt, and carbon fibers with a CBPC matrix werernfabricated by pultrusion. Bending strength, microstructure and different manufacturing processrnparameters were evaluated. The temperature effect was evaluated up to 1000C. Both the ceramicrnresin matrix and the fibers show damage due to new oxide formation. Macroscopic cracks appearrnmainly due to a structural shrinkage.
