“…[3,4] Especially ballistic vests are one of the research fields in applications of these two materials. [1,2,5] The two materials are also used in combustion nozzles, gas turbines, neutron radiation absorbent, and abrasive tools. [1,3] The microstructures must be as dense as possible to provide the full potential of the properties.…”

“…Reaction-bonded silicon carbide (RBSC), reaction-bonded boron carbide (RBBC), and reaction-bonded silicon-boron carbide (RBSBC) were produced by this approach. [5,11,12] As silicon melts at %1414 °C, no high temperatures are needed to fabricate these materials. [6] Combining LSI with the advantages of additive manufacturing, parts with complex shapes can be realized.…”

Co‐extrusion by robocasting is a suitable process for fabricating multi‐material ceramic structures. In the present work, the robocasting process is used to fabricate core‐shell structures, combined with subsequent liquid silicon infiltration (LSI). Thus, reaction‐bonded silicon carbide (RBSC), reaction‐bonded boron carbide (RBBC), and reaction‐bonded silicon‐boron carbide (RBSBC) composites are produced. The LSI process offers the possibility to circumvent high temperatures and pressures used in traditional fabrication.Pastes with high solid loading and necessary carbon content are used in order to combine the robocasting with the subsequent LSI process. The influence of the paste rheology on the sample fabrication of multi‐material core‐shell structures of reaction‐bonded carbides is investigated. The key rheological data, such as the viscosities of the combined pastes, are correlated with the observations from the microstructural investigation using SEM. A correlation between the difference in viscosity and the core geometry could be established. Crack formation in the material combination of RBSC and RBBC is found and compared with layered multi‐material structures of reaction‐bonded carbides. Residual stresses, which can be used to explain the crack formation, were investigated using Raman spectroscopy.This article is protected by copyright. All rights reserved.

“…There is also a large number of investigations over the application of Silicon nitride (Si 3 N 4 ), Titanium boride (TiB 2 ), Aluminium nitride (AlN), sialons (SiAlON), glasses [4,6], and ceramic composites reinforced with metal or intermetallic phases [3]. Ceramic layers are most often joined with other layers absorbing the energy, by the adhesive bonding method [1]. In literature the stress is put on the role of adhesive joints in the shaping of protective properties of multilayer armours [5,7].…”
