“…The composites possessed relatively good dielectric properties and high flexural strength, but the fibers were susceptible to oxidation at 700°C, which was difficult to resolve 20–22 . High silica fibers have the advantages of low thermal conductivity, low coefficient of expansion, and low density, and can generally be used above 1200°C, and thus have been widely used as reinforcing materials 23,24 …”

ZrP2O7 ceramics exhibit poor mechanical properties after firing, as a major drawback. In this study, ZrP2O7 matrix composites reinforced with high silica fibers were prepared through pressureless sintering by varying the content and length‐to‐diameter ratio of the high silica fibers added to ZrP2O7 powder. After heat treatment at 1200‒1300°C, the room temperature flexural strength of the ZrP2O7 matrix composites with different amounts high silica fibers having different aspect ratios was 14.9‒45.2 MPa, the bulk density was 1.90‒3.03 g·cm−3, the apparent porosity was 2.37%‒39.39%, and the room temperature thermal conductivity was .47‒.95 W/(m·K). With an increase in the heat‐treatment temperature, driven by sintering and fiber crystallization, strength of the interfacial layer between the fibers and the matrix inside the ZrP2O7 matrix composites decreased and then increased. The transfer and blocking effects of the interface enabled effective transfer of the stress of the matrix to the fiber‐reinforced phase and prevented crack extension. The problem of inherent crystallization affecting high silica fibers at high temperatures was relieved by the ZrP2O7 ceramic matrix composites.

“…It has become a commonly used material in the aerospace industry after metal alloys. Quartz fiber was not only light in weight, but also has good load-bearing capacity and maintains high stability [7][8][9]. In recent years, the outstanding mechanical and dielectric properties of quartz fiber have been used in aerospace high temperature radome system, which need high strength and toughness.…”

This manuscript reported the synthesis of Al2O3 coating onto quartz fiber fabric by plasma electrolysis spray for enhanced thermal conductivity and stability. The nano- and micro-sized clusters were partially observed on the coating, while most coating was relatively smooth. It was suggested that the formation of a ceramic coating was followed as the nucleation-growth raw, that is, the formation of the coating clusters was dependent on the fast grow-up partially, implying the inhomogeneous energy distribution in the electrolysis plasma. The deposition of the Al2O3 coating increased the tensile strength from 19.2 to 58.1 MPa. The thermal conductivity of the coated quartz fiber was measured to be 1.17 W m−1 K−1, increased by ~45% compared to the bare fiber. The formation mechanism of the Al2O3 coating was preliminarily discussed. The thermally conductive quartz fiber with high thermal stability by plasma electrolysis spray will be widely used in flexible thermal shielding and insulation materials.

“…In this manner chills remain broadly utilized by foundry engineers for the generation of comprehensive and excellence castings. Smaller scale contraction or scattered penetrability in the composite can be reduced by the reasonable area of chills [7][8][9]. Chills extract heat at a faster rate and promote directional solidification.…”

Spectral broadening and self-compression of negatively chirped visible femtosecond pulses in fused silica A I Aristov, Ya V Grudtsyn, L D Mikheev et al. ABSTRACTA review of a host of relevant literature on the composites leads to some important observations on the gap that prevails for developing the composite with increased strength to weight ratio, improved thermal properties and reduced corrosion rate with the addition of fused SiO2 dispersoid for the nickel based alloy. In the arena of engineering, metallurgists look for techniques to improve the thermal, corrosion and chemical properties of the materials. In this connection an investigation has been carried out to fabricate and evaluate the corrosion, chemical and thermal properties of chilled composites consisting of nickel matrix with fused silica particles (size 40-150 μm) in the matrix. The main objective of the present research is to obtain fine grain Ni/SiO2 chilled sound composite having very good properties. The dispersoid added ranged from 3 to 12 wt. % in steps of 3%. The subsequent composites cast in molds containing metallic and non-metallic chill blocks (MS, SiC & Cu) were tested for their microstructure, chemical, thermal properties and corrosion behavior.
