“…Flexural strength was measured by 3-point bending tests on 3 mm × 4 mm × 36 mm bars with a span of 30 mm at a crosshead speed of 0.5 mm/min. Fracture toughness was evaluated using single-edge notched beam (SENB) on 2 mm × 4 mm × 22 mm bars with a 16 mm span and a crosshead speed of 0.05 mm/min [19,20]. The reported averages and standard deviations of flexural strength and fracture toughness were calculated from a minimum of six bars.…”

Microstructural evolution and performance of carbon fiber-toughened ZrB2 ceramics with SiC or ZrSi2 additive

ZrB 2 -SiC/ZrSi 2 ceramics containing 30 vol% carbon fiber (C f ) additive were fabricated by hot pressing at low temperature (1500 ℃) using submicron ZrB 2 powders, and their microstructural evolution and performance were investigated. The addition of SiC or ZrSi 2 significantly reduced the onset sintering temperature and enhanced the densification of ZrB 2 . ZrB 2 -ZrSi 2 -C f showed poor performance owing to the serious fiber degradation, while the fiber degradation was effectively inhibited in ZrB 2 -SiC-C f resulting in high fracture toughness, substantial fiber pull-out, and non-brittle fracture mode for such material. The critical thermal shock temperature difference of ZrB 2 -SiC-C f was up to 741 ℃, significantly higher than those of ZrB 2 -SiC/ZrSi 2 and ZrB 2 -ZrSi 2 -C f . Moreover, this composite displayed a good oxidation resistance at 1500 ℃ in air.

“…It has also been reported that other mechanisms of toughening are activated, either crack deflection [275] or, in weak matrix composites such as porous Cf-ZrB2 [279] , with a fracture mechanism similar to that which occurs in oxide-oxide CMCs [282]. Table 9 [275], [276], [278], [279], [281], [283] summarises the thermomechanical behaviour achieved by hot pressed UHTCMCs, including microstructural and physical properties.…”

“…(1) The continuous fibrous reinforcement is coated with interphase layers, typically pyrolytic carbon [276] or ceramic [275,277] to enhance the fracture toughness of the composite and protect the fibres during pressing. As a result of the high refractoriness of UHTCs, the temperature and the pressure applied need to be much higher compared to other manufacturing processes, e.g.…”

April 1 st 2019 he was also the Deputy Head of the College of Engineering & Physical Sciences. He has been active in ceramics processing research since 1981 and has published ~220 refereed papers, as well as editing or contributing to 19 books and holding 7 patents with an 8 th recently submitted. He has attracted 129 research grants to date, totalling ~£16.5M, this includes a current portfolio of about £1.9M. The focus of his research is the generation of both the necessary scientific understanding and the required engineering solutions for the design and development of materials and process routes that display technical and/or economic advantages over existing approaches. The range of products worked on ranges from nanostructured to traditional ceramics, interpenetrating composites to ultra-high temperature ceramic matrix composites. He has worked closely with industry to translate key developments, e.g. through the creation of a spin-out company to develop a ceramic sensor for measuring soil matric potential (1991), or via licensing, e.g. manufacturing routes for producing engineering ceramic foams (1995) and nanostructured ceramics (2012). He has supervised 35 Ph.D. students and 2 M.Phil. students to successful completion and 38 postdoctoral researchers. A further 7 Ph.D. students and 6 postdoctoral researchers are currently being supervised with more positions currently advertised. His research has received both national and international recognition; he has given ~65 keynotes, plenary and invited talks at international conferences, whilst the Institute of Materials, Minerals and Mining has awarded him the Holliday Prize (1995), Ivor Jenkins Medal
