Due to global environmental regulations, the change to electric vehicles is getting faster from internal combustion institutions to eco-friendly electric vehicles and the technology and new products for soundproofing and lightweight materials are required.
The core technology of developing soundproofing material that overcomes sound meta structure is based on
: Securing acoustic meta-structure design technology that increases the effective density of air (patent application), securing multi resonant mode technology that can block ultra light weight and broadband (patent registration), developed wheel guard products for road sound blocking undercover and tire composite noise blocking and developed multi-functional(Soundproof, electromagnetic shielding, antibacterial) composite wave-meta material products.
