Description

ResoNix CLD Squares

 

 

ResoNix CLD Squares is a constrained layer damper that is a combination of butyl rubber and aluminum that is adhered onto panels of the car to lower structure-borne vibration and resonance.

It works by using a viscoelastic layer (the butyl) and a constraining layer (the aluminum) to convert mechanical energy (the vibration of a panel) into heat via the viscoelastic properties of butyl while the constraining layer helps the panel keep its shape and resist deformation.  The primary way that CLD achieves this is through shear forces in the butyl layer caused by being constrained between the panel and the constraining layer while the panel is vibrating (bending). When the panel flexes and deforms, the viscoelastic layer naturally resists and wants to “snap” back into place. See Figure 1.

ResoNix CLD Squares should be used where you want to cut down on any structure-borne vibration and resonance. Long, flat, and thin panels, like outer door skins, door panels, quarter panels, and roof skins are the biggest offenders. Reducing structure-borne vibration helps lower the overall noise floor of the vehicle while also lowering the resonance caused by sound systems to an acceptable level.  This can result in a faster decay of bass and midbass frequencies.  Slow decay in these frequencies can cause “muddy” sounding bass response or can make it seem like repeated fast bass notes are blending together.  See figure 2.

ResoNix CLD Squares are the best choice for all applications where you want to attack structure-borne vibration to reduce undesirable resonance and vibrations. We chose a butyl compound specifically designed for vibration damping and paired it to an aluminum layer thickness that is as stiff as possible, without risking weakening the adhesive bond on contoured panels.
