Characterization of hydroxyapatite- and bioglass-316L fibre composites prepared by spark plasma sintering
Guo, Hongbo, Miao, Xigeng, Chen, Yanming, Cheang, P., & Khor, Khiam A. (2004) Characterization of hydroxyapatite- and bioglass-316L fibre composites prepared by spark plasma sintering. Materials Letters, 58(3-4), pp. 304-307.
To improve the mechanical properties of pure hydroxyapatite (HA) ceramics and pure 45S5 bioglasses, HA-316L fibre composites and bioglass 45S5-316L fibre composites were produced by spark plasma sintering (SPS) at 950 oC and 850 oC respectively. While the HA phase in the HA-316L fibre composites did not decompose after the SPS process, microcracks were found around the 316L fibres in the composites. Consequently, the HA-316L fibre composites could not effectively improve the mechanical properties of the pure HA ceramics. In contrast, the bioglass 45S5-316L fibre composites showed no microcracks around the 316L fibres and thus exhibited bending strengths of up to 115 MPa.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
