TL;DR: In this article, a three-phase composites with excellent electromagnetic wave absorption properties based on carbon black (CB) and BaTiO3 (BT) nanoparticles embedded into polyvinylidene fluoride (PVDF) were prepared using a simple blending and hot-moulding technique.
Abstract: Novel three-phase composites with excellent electromagnetic wave absorption properties based on carbon black (CB) and BaTiO3 (BT) nanoparticles embedded into polyvinylidene fluoride (PVDF) were prepared using a simple blending and hot-moulding technique. When the composites have filler contents of CB 10 wt% and BT 5 wt%, the reflection loss can reach −38.8 dB at 9.2 GHz, and the reflection loss is less than −10 dB in the frequency range from 3.5 to 18.0 GHz with an absorber thickness of 1.5–5.0 mm. Compared to the two-phase composites of CB/PVDF and BT/PVDF, the three-phase composites showed superior absorption properties. The Debye relaxation theory was used to explain the enhanced absorption properties.

TL;DR: In this paper, the electric resistance of woven SiC fiber-reinforced SiC matrix composites was measured under tensile loading conditions and the results showed that the electrical resistance is closely related to damage and that real-time information about the damage state can be obtained through monitoring of the resistance.

TL;DR: In this paper, a fractal approach to crack branching (bifurcation) in glass and the fracture behavior of machineable hydroxyapatite is presented. But the authors focus on the effects of micro-structural effects in ceramics.
Abstract: Topics addressed include finite element stress analysis and crack path prediction of imploding CRT; fractography and fracture mechanics of combustion growth diamond thin films; the fracture behavior of machineable hydroxyapatite; a fractal approach to crack branching (bifurcation) in glass; the fracture of glass-ionomer cements; the effect of quartz particle size on the strength and toughness of whitewares; and a proposed standard practice for fractographic analysis of monolithic advanced ceramics. Also treated are thermal exposure effects on ceramic matrix composites, fractography applied to rock core analysis, fractography of flexurally fractured glass rods, the fractographic determination of K(IC) and effects of microstructural effects in ceramics.
