Abstract: The present invention discloses a method for producing unidirectional hybrid-braided fabrics, including: preparing a first layer of 0° warps; preparing a second layer of 0° warps to a Nth layer of 0° warps; preparing an auxiliary layer of wefts; preparing binding yarns; laying and hybrid-braiding the materials prepared in steps 1-4 to obtain unidirectional hybrid-braided fabrics; and cutting and winding. The 0° warps and wefts of the invention are made of two or more layers of different fibers that are laid in a single direction and finally hybrid-braided. Therefore, two or more different types of materials can be laid, thereby ensuring the uniform distribution and thickness of the fibers in different areas of the hybrid-braided fabric. The grammage of different 0° warp fiber layers can be adjusted freely in a range of 30-3000 grams/m2, thereby realizing performance and cost designability of a composite material.

Abstract: A laser control circuit, comprising at least two laser tubes and a control unit controlling the at least two laser tubes respectively; the control unit sends control signals to the at least two laser tubes to control startup/shutdown thereof. The control unit comprises: a main pulse signal generator and a logic control unit; the main pulse signal generator, the logic control unit and the at least two laser tubes are connected successively; and the logic control unit classifies the control signals into different types of control signals and sends to the at least two laser tubes, causing the at least two laser tubes to present different working conditions. The laser control circuit has more flexible control over the laser tubes, reduces working current of the laser tubes and allows the working current to be steadier, thus avoiding peak interference.
