패널 조립체(10)는 다양한 응용례에서 사용될 수 있으며, 그러한 예로는 소음이나 진동을 줄이거나 단열을 제공하거나 구조적 완전성을 향상시키는 다양한 차량에의 응용례가 있다. 예시적인 실시예에 따르면, 패널 조립체(10)는 금속으로 제조되는 메인 패널(12), 역시 금속으로 제조되는 하나 이상의 음향 감쇠 패치(14,16) 및 구속층 구조물에서 패치(14,16)를 메인 패널(12)에 결합시키는 접착층(18)을 포함한다. 음향 감쇠 패치(14,16)는 그것의 음향 감쇠 특성을 현저히 손상하지않고 패널 조립체(10)의 성형성을 향상시키도록 설계된 하나 이상의 성형부(30,32)를 포함할 수 있다. 상이한 형태의 성형부로 패치의 내부에 위치된 내부 성형부(30)(예컨대, 개구, 홀, 슬릿, 슬롯 등) 및 패치의 외주를 따라 위치된 외부 성형부(32)(예컨대, 돌출부, 핑거부, 리세스, 파형부 등)가 포함된다.

    A panel assembly for use in any number of different applications, including a variety of vehicle applications, that reduces noise or vibrations, provides thermal insulation, and/or improves structural integrity. According to an exemplary embodiment, the panel assembly includes a main panel made from a metal, one or more sound damping patches also made from a metal, and an adhesive layer that joins the patches to the main panel in a constrained layer construction. The sound damping patches may include one or more forming features, which are designed to improve the formability of the panel assembly without significantly impairing its sound damping characteristics. There are different types of forming features, including internal forming features (e.g., openings, holes, slits, slots, etc.) located within the interior of the patch and external forming features (e.g., projections, fingers, recesses, waveforms, etc.) located along the perimeter of the patch.
