Constrained Layer Damping (CLD) is a system used to suppress vibrations in various machineries such as ship structures, vibrations caused due to propellers, mounted machinery, etc. It is made of two sheets that are rigid, however, have poor damping properties. A damping material such as viscoelastic is placed between the two sheets. When the surface vibrates, it is trapped between the two sheets and degenerated in the constrained layer as sheer energy. Vibration damping materials are widely used in automotive applications to dampen the vibration and sounds of the engine, thus reducing road noise.
Global constrained layer damping market was valued at US$ 429.83 Mn in 2021 in terms of revenue, exhibiting a CAGR of 6.35 % during the forecast period (2022 to 2030).
Drivers
The automotive industry constantly aims at reducing vehicle weight while striving to improve the noise, vibration, and harshness performance. This increases the demand for improved vehicle acoustic performance with lightweight acoustic materials, treatments, and components. CLD comprises viscoelastic material layers with high stiffness, which help dissipate vibratory energy in the structure through sheer deformation of the viscoelastic layer. Thus CDC proves to be an efficient technique to subdue throbbing and sound in these structures, due to which the demand for CDC is in turn increasing. This is a major factor driving growth of the constrained layer damping market. Integration of lightweight acoustic materials allows for enhanced vehicle efficiency, especially in heavy vehicles such as pickup trucks and SUVs, while reducing the noise, vibration, and harshness (NVH) impacts. Increasing demand for lightweight automotive materials to lower fuel consumption, in turn, is boosting demand for constrained layer damping.
The Covid-19 virus has caused widespread disease in countries around the world since the start of the epidemic in late fall 2019, leading to the declaration of a global health emergency by the World Health Organization. The losses in the global constrained layer damping market will be severe, with coronavirus disease already affecting it.

Market Trends
Among product type, the steel segment is the largest segment among product types which is expected to a revenue of US$ 744.88 Mn by 2030. Steel manufacturers working with composites engineers and laminates to develop vehicle parts are increasingly focusing on weight reduction, noise reduction, and cost saving. To reduce structure-borne noise in the vehicle, silent steel (sandwich steel) is used. Sandwich steel is used as a damping material in various applications to control noise and vibration in vehicles such as power train application. The excellent properties of steel such as high durability, stiffness, and toughness enables it to act as an excellent layer that helps in the protection of damping material.

Constrained Layer Damping (CLD) is a system used for the suppression of vibrations in automotive and marine applications. The rampant growth of the automotive and construction sectors coupled with the rising demand for lightweight vehicles in order to increase the fuel efficiency of vehicles are increasing the demand for damping systems. Increasing demand for premium interiors in emerging economies such as India, China, and ASEAN countries is augmenting growth of the CLD market. Moreover, several consumers are increasingly inclined towards integrating premium grade interiors in non-premium cars, to enhance the aesthetic appeal of the interiors and improve comfort. Due to this, several automobile companies are increasingly adopting constrained layer damping systems to offer aesthetically appealing products of lower quality, made from plastic from companies such as GM & Daimler Chrysler underdevelopments which include dash panels, roof panels, floor panels, floor pans & trunk floors.
Market Dynamics
North America is projected to hold the second dominant position in global constrained layer damping market, followed by Europe and Asia Pacific over the forecast period. The growth of this market is driven by increasing demand for lightweight acoustic materials to improve vehicle performance, rampant growth in automotive sales, and growing consumer preference for premium materials in automotive interiors. Increasing demand for economical and long-lasting vehicles due to rising fuel prices in North America. According to Energy Information Administration (EIA) the gas prices is expected to average $1.19 per litre over the year (2018) which is highest since 2014. Thus, manufacturers are increasingly focusing on reducing the overall weight of vehicles by incorporating CLDs, this in turn, is boosting growth of the constrained layer damping market. High cost benefits associated with rapid adoption of such materials for both suppliers and buyers is expected to positively impact the economic growth of the CLD market during the forecast period.
