“…For the matrix of UHTCMCs, ZrB2/SiC powder mixtures were prepared by wet ball milling and drying. With these mixtures, water-based slurries were prepared, according to previous works [12]. The composites were fabricated infiltrating the UD fabrics with the slurries by hand lay-up and subsequently stacking layers in 0/90° configuration (Fig.…”

“…Previous works have already identified the several steps involved in the development of these composites, such as the design of matrix compositions, development of new processes including manual fibre preform impregnation or filament winding [12], densification of the composites through hot pressing or spark plasma sintering [10], mechanical characterization at room and elevated temperature, oxidation studies from 1500 to 2100 °C and arc jet tests in plasma wind tunnel facilities [10,[13][14][15][16]. Results obtained have shown that similar microstructures and properties can be achieved by HP and SPS, with a reduction of temperature and processing time in case of SPS [17,18].…”

“…Carbon coating was shown to be able to modulate the fiber-matrix bonding well to balance the trade-off between strength and toughness. The flexural strength and fracture toughness of C f /ZrB 2 -based composite can reach 631 MPa and 15.7 MPa·m 1/2 at RT, with flexural strength of 676 MPa at 1800 °C, showing the potential performance development of C f /ZrB 2 -based composites 52 . In this work, the work of fracture of C-PDA coated C f /ZrB 2 -based composite is clearly higher than those of C f /ZrB 2 -based composites, also 2 orders of magnitude higher than that of ZrB 2 -based ceramics (~ 100 J/m 2 ) 53 and more 13 times than that of non-C-PDA coated C f /ZrB 2 -based composite (~ 754 J/m 2 ) 35 .…”

“…In contrast, for the non-C-PDA coated fiber-reinforced high-temperature composite 35 , the load rapidly drops to a very low level after To clarify the position of the properties of the composites, the data were compared with those reported in the literature. Figure 7i shows the data for room temperature (RT) properties of fiber/ZrB 2 -based composite 16,19,43- 52 . In this work, the work of fracture of C-PDA coated C f /ZrB 2 -based composite is clearly higher than those of C f /ZrB 2 -based composites, also 2 orders of magnitude higher than that of ZrB 2 -based ceramics (~ 100 J/m 2 ) 53 and more 13 times than that of non-C-PDA coated C f /ZrB 2 -based composite (~ 754 J/m 2 ) 35 .…”

The low deposition time efficiency and small thickness limit the expansion of polydopamine (PDA) application to fiber-reinforced high-temperature ceramic composites. In this work, the electric field-assisted polymerization (EFAP) route was developed to improve the deposition time efficiency of PDA coating and overcome the thickness limitation. Carbonized polydopamine (C-PDA) coating was used as the interphase of carbon fiber-reinforced ZrB2-based composites (Cf/ZrB2-based composite) to bond rigid fibers and brittle ceramics, where C-PDA coating was prepared by the carbonization of PDA coating. Firstly, uniform and dense PDA coatings were deposited on carbon fibers (Cf) by EFAP. The thickness of PDA coating reached the micron level (over 1800 nm) for the first time. Benefiting from the EFAP route promoting the oxidation process of dopamine (DA) and accelerating the aggregation and in-situ polymerization of DA and its derivatives on the surface of Cf, the deposition rate of PDA coating reached 5589 nm/h, which was 3 orders of magnitude higher than that of the traditional self-polymerization process. By adjusting the EFAP parameters (e.g. DA-concentration, current, and deposition time), the thickness of PDA coating could be conveniently designed from nano-scale to micro-scale. Then, PDA coating was pyrolyzed to obtain C-PDA coating. C-PDA coating was well bonded on Cf without visible cross-sticking among neighboring fibers. C-PDA coating presented a layered structure and the thickness of C-PDA coating could be designed by controlling the thickness of PDA. C-PDA coating was used as the interfacial phase of the Cf/ZrB2-based composite, which ensured that the composite possessed good load-bearing capacity and thermal stability. Moreover, extraordinary damage resistance of the composite was achieved, with work of fracture up to 9936 ± 548 J/m2 at room temperature and 19,082 ± 3458 J/m2 at 1800 °C. The current work provides a high time efficiency processing route for depositing PDA coating on carbon fibers and demonstrates the attractive potential of PDA coating in fiber-reinforced high-temperature ceramic composites.

“…Finally, a hot-pressing cycle was carried out at 1900 ℃ for 20 min and a 35 MPa of pressure was applied from 900 ℃, similar to those of Refs. [39][40][41]. To control the thickness of the sheet and to obtain the same dimensions, each sheet was created by introducing the same amount of ceramic powder loading and dispersant into a mould of 15 cm × 15 cm.…”

A new additive technique for manufacturing of short fibre-reinforced ultra-refractory ceramics is presented. This technique allows the fabrication of solvent-free, thin (~100 µm), flexible, and easy-to-handle sheets suitable for fabricating homogeneous or layered structures. A large range of compositions, in terms of matrix and fibre volumetric contents, from 0% to 100% is possible. The amount of short carbon fibres incorporated in the sheets ranged from 20 to 50 vol%, whereas the fibre length ranged from 3 to 5 mm. The matrix composition investigated with this technique consisted of ZrB 2 /SiC/Y 2 O 3 . By increasing the fibre amount from 35 to 50 vol%, an improvement of mechanical properties was observed. Four-point flexural strength (σ) ranged from 107 to 140 MPa, depending on the amount of carbon fibres (C f ). The same holds true for the work of fracture, ranging from 108 to 253 J/m 2 . Functionally graded composites were fabricated by overlapping sheets with a fibre gradient (0%-50%).
