説明
Carbon fiber reinforced ceramics (CFRCs) were prepared from PAN based carbon fiber (CF) and aluminum-phosphate solution (ACIDOPHOS 120M: ACP) as a matrix precursor.<BR>ACP was easily impregnated for CF, because it was water soluble. Therefore, these CFRCs showed high-volume fiber contents. As a result, it gave higher mechanical properties of CFRCs.<BR>The unidirectional sheets of high performance carbon fibers impregnated with ACP were dried at 80°C to make the prepreg sheets. These prepreg sheets then were laminated into CFRC plate by a hot-press molding (processing pressure>10MPa, maximum processing temperature from 200 to 280°C) and were subsequently heated in Argon up to 500°C.<BR>Addition of small amounts of metal oxides, for example: Al2O3 (10 wt %) or MgO (2 wt %) or ZnO (4 wt %) into the ACP remarkably improved the operation efficiency.<BR>The result of X-ray analyses indicate that the 500°C heat-treated matrices were mainly composed of aluminum phosphate (AlPO4) and certain amount of amorphous contents. But the amorphous contents was slightly observed in the matrix which was added with Al2O3.<BR>The obtained CFRCs exhibited the following characters: fiber volume of 40-50 wt %, maximum bending strength of 553 MPa, and maximum bending modulus of 80 GPa.
