AI Technical Summary

Technical Problem

Particle composite sound-absorbing plates are prone to structural deformation and cracking when exposed to large noise vibration for a long time, which affects their service life, and at the same time, their own structural strength is insufficient.

Method used

A perforated aluminum plate is used as the support base plate, and a honeycomb core structure is adhered to the surface, and the particle raw material and binder are mixed in the honeycomb core, so that it can fully and evenly enter the honeycomb core through vibration and pressing to form a particle composite sound-absorbing plate.

Benefits of technology

Through the embedded skeleton structure of the aluminum honeycomb core, the structural strength and stability of the particulate composite sound-absorbing plate are improved, while maintaining good sound absorption and noise reduction performance and extending service life.
