Development trend of advanced composite high temperature thermal equipment
2023-10-27The so-called composite material refers to a multiphase new material system prepared by two or more component materials using a certain process technology, and its comprehensive performance is better than the respective component materials. Advanced composite material refers to the composite material composed of high performance reinforcement such as carbon fiber, aramong and other high performance heat resistant polymers, including metal base, ceramic base and carbon (graphite) base and functional composite material. Each component material of composite material plays a synergistic role in performance. Compared with traditional materials, it has high specific strength, light weight, high specific modulus and good fatigue resistance. And good vibration damping performance and many other advantages, widely used in the national defense industry, aerospace, automobile manufacturing and other fields.

Recent progress and challenges of transparent AlON ceramics
2023-05-10Ceramics and their composites have been widely investigated for various applications due to their unique chemical and physics properties [1−7]. Among them, transparent ceramics have an extensive application in the business domain and the military industries due to their outstanding optical, physical, and mechanical properties [8−10]. Among the transparent ceramics, transparent aluminum oxynitride (AlON) ceramics have been considered as one of the most important ceramics in the domes, infrared and visible windows, and transparent armors, etc [11−13]. Compared with the single crystal sapphire, which is well-known as the hardest transparent ceramics, the polycrystalline AlON ceramics have similar characteristics on strength, hardness, and optical properties, but offer more flexibility in size and shape [14,15]. Therefore, AlON ceramics have attracted a growing investigation. γ-AlON is a solid solution of Al2O3and AlN [16,17]. Many methods have been explored to prepare AlON powder or AlON ceramics, such as solid-state reaction [18], carbonization method for Al2O3[19,20], chemical vapor deposition [21], sol−gel method [22,23], and solution combustion synthesis [24]. The band gap of AlON was measured to be 6.2 eV [25]. TU et al [26] employed a first-principles density functional theory (DFT) to study the on-site preference of Al vacancy and Natoms in γ-AlON. The band gap and bulk modulus structural model of γ-AlON, as the local structure of the Al23O27N5were calculated to be 3.99 eV of N atoms and Al vacancies in γ-AlON is not and 200.9 GPa, respectively. Given a wide band clear. The properties of γ-AlON are displayed in gap together with low photon energy and high Table 1 [14].
