Benefits of technology
This patented technology describes an absorbent element used in vehicle radar systems that can be easily assembled without requiring expensive tools or complicated processes. It achieves this through combining different materials together into one unit instead of adding separate parts like metal foils. Additionally, it simplifies its design while improving production efficacy. Overall, these technical improvements improve performance and cost-effectiveness compared to existing designs.
Problems solved by technology
This patented technical problem addressed by this patents relates to improving the performance of microswitches due to their ability to reduce reflection caused by metals or other substances that may come within small cavities inside them.

Abstract
The invention relates to an integral forming process of a zigzag hollow structure composite material wave-absorbing component. The integral forming process comprises the following steps: S1, a carbon fiber prepreg meeting design requirements is selected, layer design is carried out, and the number of layers and the angle of the layers are determined; S2, a reflecting plate is designed to be of a flat plate structure, prepreg is laid on a forming tool according to the designed layer number and angle, the forming tool designs a flange and a pressing plate, and the reflecting plate is subjected to net-size curing forming firstly; S3, after the reflecting plate is cured, an adhesive film, a wave-absorbing body inner skin, a wave-absorbing body honeycomb core and a wave-absorbing body outer skin are laid on the reflecting plate in sequence, then a vacuum bag is manufactured, and the vacuum bag is co-glued, cured and formed through an autoclave; S4, demolding is carried out after molding; and S5, sawteeth and assembling connecting holes are machined to obtain the sawtooth-shaped hollow structure composite material wave-absorbing component. The strength meets the requirement, and the weight is light; the manufacturing difficulty is low and the efficiency is high; the processing cost is low; the process stability is good, and the bonding strength reliability is improved; and the gluing quality and stability are improved.
