Characterization of fiber/matrix interfaces in composites with a boron nitride matrix

Fabrication and properties of borazine derived boron nitride matrix wave-transparent composites reinforced by 2.5 dimensional fabric of Si–N–O fibers

“…The combination of these two microstructure features gave rise to the massive energy-dissipated fiber pull-out. In addition, it is believed that the arrangement preference of the BN matrix surrounding the reinforcing fibers also plays an important role in controlling the fracture behavior of the BN base composites [37]. While most of the derived BN matrix was non-directional distributed within the present composites, a thin layer matrix surrounding the reinforcing fibers seemed to display an arrangement preference.…”

Polymer-Derived Boron Nitride: A Review on the Chemistry, Shaping and Ceramic Conversion of Borazine Derivatives

“…Then, the same group published several papers in which they focused on the characterization of C/BN composites, i.e. , thermal stability and mechanical properties (Friction and wear properties) [ 78 , 79 , 80 , 81 ]. In our group, carbon fibers-reinforced BN matrix composites (C/BN composites) were manufactured after 10 polymer impregnation pyrolysis (PIP) cycles with PB60 ( Table 1 , first PIP cycles) and PB50 ( Table 1 , last PIP cycles) and dissolved in THF [ 82 ].…”

High-temperature properties and associated structure evolution of continuous SiNO fiber-reinforced BN composites for wave transparency

“…5 shows large amounts of fibers pulled-out from the matrix, and the surfaces of the fibers display good adherence with some of the matrix remaining, which can effectively transfer the stress from the matrix to the fibers. Generally, the mechanical properties of fiber-reinforced composites are determined by the combination of fiber strength, matrix properties, and the behavior of the fiber/matrix interface [25,34,35]. For continuous fiber-reinforced CMCs, the fiber/matrix interface is especially critical.…”
