Properties Of Composites

In Situ transformed carbon fibers/Al2O3 ceramic matrix nanocomposites with Cao–MgO–SiO2 sintering agent were prepared by hot-pressed sintering technology in vacuum. In the sintering process, pre-oxidized polyacrylonitrile fibers (below named as pre-oxidized PAN fibers) were used as the precursors of In Situ transformed carbon fibers. The micro/nanostructure of composites and interface between In Situ transformed carbon fibers and matrix were investigated, as well as the properties of composites. The results showed that the composites could be sintered well at a relatively low temperature of 1650 °C. During the sintering, the precursors, pre-oxidized PAN fibers, were In Situ transformed into carbon fibers, and the In Situ transformed carbon fibers had the graphitelike structure along the fiber axial direction. The carbon atoms arrangement in the surface layer of the fiber was more orderly than the core. A typical diffraction peak of carbon fiber at 26°, which corresponded to the (002) crystal plane, was observed, and the inter-planar spacing was approximately 0.34 nm. The CaO–MgO–SiO2 sintering agent formed MgAl2O4 and CaAl2Si2O8 phases in the interface between In Situ transformed carbon fibers and matrix, therefore improving the interface bonding, and thereby modifying the mechanical properties of the composites.

Supercritical Carbon

In this paper , a new treatment method based on polyacrylonitrile (PAN) based carbon fiber treated by supercritical carbon dioxide (SCCO2) is proposed. This method aiming to obtain a controlled interface is green and pollutionless . The surface state of carbon fibers both untreated and treated on different temperature was studied by using SEM, AFM and XPS. The results show that SCCO2 can erode the surface of carbon fibers. Roughness of modified carbon fiber is higher than that of the untreated. Interfacial properties of the treated carbon fiber /epoxy microcomposites were improved. Interfacial shear strength (ILSS) of CFRP shows that treated carbon fiber /epoxy at a lower temperature can be increased by 17.35%, which means that an effect of optimized interface is obtained.
