Continuous SiC fiber-reinforced SiC matrix composites (SiCf /SiC) have been considered to be a key material as structural components for aerospace and energy fields. This paper reviews novel fabrication process of continuous SiCf /SiC composites with high performance based on interfacial and microstructure control and our approach to improvement of mechanical and thermal properties of SiCf /SiC composite based on modeling and analysis. The simple fabrication process of two-dimensional SiCf /SiC composite using sheet stacking and hot-pressing based on interfacial and microstructure control was developed, and dense SiCf /SiC composite with excellent mechanical and thermal properties was successfully obtained. Furthermore, novel fabrication process of SiCf /SiC composite using EPD process was proposed and it was demonstrated that EPD process is expected to be an effective way to control the fiber/matrix interface and the microstructure of SiCf /SiC composite with high performance. Interfacial properties of SiCf /SiC composite were quantitatively evaluated by push-in test using nanoindenter, and these quantitative results well agreed with the results on their mechanical properties, and these results lead to the material design of the SiCf /SiC composite with high mechanical properties and the optimization of its fabrication process. Simple model of thermal conductivity of SiCf /SiC composite based on series model of multilayered structure was suggested by our experimental data, and higher thermal conductivity of SiCf /SiC composite was successfully achieved by microstructure control.

“…The effect of microfiber/matrix interface on mechanical properties of composites has been widely explored [1e7]. Several established methods, including the push-out test [6,8], the pull-out test [9e11], the microbond test [12,13], the microindentation test [14,15], and the fragmentation test [7,16,17], etc, have been employed to characterize the interfacial strength. For example, Rebillat et al used push-out tests to investigate the interface and interphase characteristics of strongly bonded twodimensitonal (2D) SiC/C/SiC composites [5].…”

a b s t r a c tCarbon nanotubes (CNTs) have been considered an ideal reinforcement for light-weight and highstrength ceramic matrix composites. Understanding the interfacial properties between CNTs and the matrix is crucial for engineering the desired properties in such composites. Here in-situ pull-out experiments with a polymer derived ceramic (PDC) matrix are carried out with both pristine CNTs and CNTs coated with Al 2 O 3 (CNT/Al 2 O 3 ) produced by Atomic Layer Deposition (ALD), using micro-fabricated devices in a scanning electron microscope. This carefully designed comparative study makes it possible to better understand the interfacial interactions between CNTs and PDC matrices. The interfacial shear strength (IFSS) of CNT-PDC is 9.99 ± 2.84 MPa, while the IFSS of (CNT/Al 2 O 3 )/PDC with~3 nm Al 2 O 3 coating thickness is 14.52 ± 2.66 MPa, demonstrating a 45.3% improvement. The non-linear failure observed with the coated CNTs is also indicative of energy dissipation mechanisms that promote toughening in ceramic matrix composites. The improved properties in (CNT/Al 2 O 3 )/PDC are believed to originate from increased surface roughness, which leads to mechanical interlocking at the interface during the pull-out process. The combination of special interlayer structures such as ALD Al 2 O 3 and strong CNTs opens up interesting opportunities for improving the mechanical properties of ceramic nanocomposites reinforced by CNTs.

“…It is characterised by the simplified consideration of three-dimensional fibres as one-dimensional entities. The debonding load P d in pull-out tests can be related to τ d by Eq.1 using a shear lag analysis [16], [17], which also can be extended to push-out tests [18].…”

We investigate SiC fibre reinforced copper as an additional layer at the highly loaded zone between plasma facing material (W) and heat sink (CuCrZr) for a fusion reactor divertor.Copper has a high thermal conductivity of 380 Wm -1 K -1 but a very low strength and creep resistance at 550°C. Therefore copper is reinforced with SiC long fibres (SCS6, Specialty Materials) having excellent high temperature strength.The fibres were galvanically coated with an 80-µm-thick copper layer as matrix. Hot isostatic pressing at 650°C was applied to form the composite material. The interfacial shear strength calculated from push-out tests was ̴ 6 MPa.Adding a 100-nm-thin titanium interlayer deposited by magnetron sputtering led to a higher adhesion of the SiC fibres in the copper matrix. Titanium reacted with the carbon surface of the fibre to TiC and formed with copper the alloy Cu 4 Ti during heat treatment and increased the interfacial shear strength to 70 MPa.
