Experimental study on parameter optimization of the maximal influencing factor layer of alternately laminated anisotropic damped structures was carried out with dynamic mechanical analyzer (DMA Q800).

In the multi-layer circuit board manufacturing process, the laminating technology is an important aspect of the quality and reliability of laminated board carving the final quality plays a key role.

A composite interlayer suitable for using laminated glass includes a layer of plasticized polyvinyl butyral sandwiched between second and third polymeric layers.
