  • Patent number: 12251862
    Abstract: A metal-resin composite, a surface treatment method, and a substrate of a printed circuit board (PCB) for high-frequency and high-speed signal transmission comprise a surface-treated metal, and the surface-treated metal includes a nano-scale pore array that is used for filling of a resin and vertically extends from a surface to an interior of a metal, where nano-scale pillars are provided to extend from bottoms to openings of nano-scale pores of the nano-scale pore array. The pillar-in-pore structure makes a resin entering a nano-scale pore have an ultra-high anchoring effect on a resin body outside the nano-scale pore. Therefore, on the premise of not using an additive such as a T liquid or a coupling agent, the present disclosure greatly improves a tensile bonding strength at an interface between a resin body and a metal substrate, and also eliminates a decline in an interfacial bonding strength of a composite.

  • Patent number: 12214556
    Abstract: Some embodiments of the disclosure disclose a space assembly system based on fusion of on-orbit additive manufacturing and ground-based launch. In some examples, an operator establishes a space manufacturing center to achieve on-orbit manufacturing of spacecraft structural components and assembles the components manufactured on orbit with spacecraft enabling modules launched from the ground to form a target spacecraft. The system includes a physical subsystem, a digital twin subsystem, and a communication subsystem. The physical subsystem includes a control unit, a communication unit, a sensor unit, an imaging and positioning device, a data storage unit, a data processing unit, an additive manufacturing unit, a space robot unit, and a raw material bin. The digital twin subsystem remotely monitors the physical subsystem. The communication subsystem establishes a connection between the physical subsystem and the digital twin subsystem and a connection between all units and devices of the physical subsystem.

  • Publication number: 20230351068
    Abstract: Some embodiments of the disclosure provides an intelligent modularized reconstruction system for a spacecraft based on analysis of a task text. In some examples, the intelligent modularized reconstruction system includes a modularized spacecraft component library, a modularized spacecraft component recommendation subsystem, a target spacecraft generation subsystem, and a three-dimensional simulation environment. In other examples, for a new spacecraft reconstruction task, the modularized spacecraft component recommendation subsystem recommends a type and a quantity of required modularized components from the modularized spacecraft component library for input task text. Each modularized component recommended by the modularized spacecraft component recommendation subsystem is used to generate three-dimensional model data of a target spacecraft by the target spacecraft generation subsystem. The three-dimensional simulation environment displays the generated three-dimensional model data of the target spacecraft.
