Stir casting was utilized to generate the composites. The AA 2618–10wt% zirconium carbide 10wt% rice husk ash hybrid composite had the highest hardness value. In comparison to pure AA 2618, it had a 72% increase. The rule of mixture was used to compute theoretical density, whereas the Archimedes rule was utilized to evaluate real density. For AA 2618, AA 2618/zirconium carbide, and rice husk ash hybrid composites, simple carbide inserts were used for turning. Surface roughness, metal removal rate, and tool wear were among the numerous responses examined. RSM was utilized to analyze and optimize the test outcomes. Feed rate was the most critical issue for surface roughness and material removal rate. Tool wear was shown to be most strongly controlled by tool speed, whereas metal removal rate was found to be least significantly influenced by the weight percent of reinforcement.

“…Laser protection materials can be classified into three types, namely, high-reflection, ablation, and thermal insulation laser protection materials. [12] High-reflection laser protection materials are mainly multilayer-structured [12,13] with low protection thresholds. Most of the previous high-reflectivity materials used for laser protection require a completely smooth surface to be maintained.…”

Aerogels are ultralight solid materials with three‐dimensional interconnected porous structures that offer considerable advantages for various protective applications. Lasers have led to various technological revolutions in aerospace, medical science, and industrial manufacturing. However, shielding against high‐energy laser irradiation using aerogels has rarely been reported. A super‐white (reflectivity >98%) boron nitride (BN) aerogel constructed using BN nanoribbons is developed in this study for high‐energy laser protection. Large numbers of BN nanoribbons serve as randomized and disordered optical nanobarriers for intense backlight scattering, which contribute to high broadband reflectivity. Combined with the low thermal conductivity of the aerogel structure and the excellent high‐temperature stability of BN, the resulting BN aerogel exhibits a high protective threshold of 2.1 × 104 W cm−2. Moreover, the BN aerogel possesses a soft porous network and a low thermal expansion coefficient, which is promising for tolerating the thermal stress and shock of local high‐temperature fields caused by laser irradiation. The successful laser shielding by the super‐white BN aerogel may be helpful for designing and fabricating advanced aerogel‐based lightweight anti‐laser materials.

Given the increasing requirements for ablative thermal protection materials, there is an urgent need for boron phenolic resin (BPR) composites with excellent high‐temperature strength properties as well as ablation performance to address the structural failure during the ablation process of these devices. Herein, modified pickling asbestos (MPA) was successfully incorporated into BPR to prepare MPA‐modified BPR (MPABPR). In addition, one‐dimensional MPA with improved dispersion and compatibility was used to fabricate a fiber‐reinforced network inside of BPR for the first time, which effectively increased the high‐temperature strength and ablation resistance of BPR. The results demonstrated that the high‐temperature strength of MPABPR was optimally improved by 25% compared to pure BPR. Meanwhile, when the content of MPA was only 5 wt%, the linear and mass ablation rates of MPABPR could reduce to 0.046 mm/s and 0.043 g/s, which were 34.3% and 23.2% lower than that of pure BPR, respectively. This study has the enormous potential to provide a new strategy for preparing high‐performance BPR matrix materials.Highlights The dispersion and compatibility of PA are improved by modification. MPA constructs a fiber‐reinforced network that can strengthen the carbon layer. The ablative properties of MPABPR have great advantages over the BPR. The compressive strength of carbonized MPABPR5 is 25% higher than that of BPR.
