Summary: With the rapid advancement of intelligent electronics, traditional low dielectric polymer matrix composites are no longer sufficient to satisfy the application requirements of high-end electronic information materials. Resin-based composites with exceptional low dielectric properties have garnered unprecedented attention, and benzoxazine-based composites in particular have piqued the interest of scholars due to their remarkable attributes. This article focuses on the design and development of modification of polybenzoxazine based on low dielectric polybenzoxazine modification methods.

Summary: The study investigated the laser-induced ablation mechanism and products of SiCf/SiC composites through numerical simulation and experiments, finding that the ablation depth could be controlled by adjusting laser parameters, with continuous-wave (CW) mode resulting in greater depth. Adjusting the scanning speed and spacing were significant factors in controlling the depth of laser-induced ablation.

Summary: Four series of benzoxazines based on nonylphenol were synthesized and utilized for water-repellent fabrics, low-k and anticorrosion applications. The chemical structure of benzoxazines was determined by spectroscopic methods. The thermal properties of benzoxazines were evaluated using TGA and DSC. It was found that poly(NPoda) exhibited excellent water-repellent properties, and poly(NP-ffa) and poly(NP-ddm) had high char residue values and low dielectric constant when incorporated with silica or SBA-15.

Summary: This study investigates the damage characteristics and ablation mechanism in fiber laser trepan drilling of 2.5D C-f/SiC composites. The findings show that low laser scanning speed can result in obvious cone angles at the exit of micro-holes, while different types of fiber in the composites exhibit specific damage characteristics during the drilling process. The research identifies layered accumulation, adherent morphology, thin shell, and bubble-like morphology as the main mechanisms of recasting layers, providing a theoretical basis for achieving high-quality micro-hole machining of 2.5D C-f/SiC composites with fiber laser drilling.

Summary: The bending property of C/C-ZrC-SiC, C/C-SiC, and C/C composites after ablation was studied, and it was found that C/C-ZrC-SiC composites exhibited better laser ablation resistance and higher bending strength retention compared to the other two. The excellent ablation resistance and residual bending strength of C/C-ZrC-SiC composites were attributed to the lowest ablative temperature and the effective protection of ZrO2 grain and ZrO2-SiO2 layer. However, the ablation damage induced a fracture behavior transformation in the composites.

Summary: We propose a novel technique for in-vacuum cavity-enhanced UV spectroscopy that minimizes mirror degradation and decreases laser-induced background. By pulsing the cavity's internal power, the UV intensity is increased only when the atom is within the cavity mode volume, while keeping the average power low. The approach demonstrates minimal impact on radiation frequency and shows potential for high-precision spectroscopy in harsh UV environments.

Summary: This study investigates the laser ablation behavior of C/SiC materials under high flow velocity conditions. A numerical simulation approach is presented by integrating a hypersonic aerothermodynamics program with finite element analysis software. Modified ablation equations for C/SiC materials incorporate wall shear stress, local pressure, and dynamic pressure. The numerical simulations are validated through a series of C/SiC ablation experiments, with the 3.0 Ma and 6.0 Ma experiments showing better ablation prediction results.

Summary: In this study, carbon-phenolic composites modified with Ti3SiC2 and Ti3AlC2 were prepared, and their ablation behavior was investigated. The addition of Ti3AlC2 particles significantly reduced the linear ablation rate and formed a protective coating during ablation. Ti3AlC2 showed better modification effect than Ti3SiC2, and increasing the volume ratio of resin and Ti3AlC2 particles further enhanced the ablation resistance.

Summary: In this study, a composite coating with reflection and energy consumption characteristics was designed and prepared to resist high-energy laser damage. The initial reflectivity of the composite coating reached 78.8% and the residual char formed during irradiation maintained its protective performance. Additionally, BN was found to improve the anti-laser performance due to its high conductivity and energy consumption properties. This study provides a new design for protecting conventional materials against laser damage.
