PRODUCT DATA SHEET KU I PERHOLLAND KUIPER SERENE CR-900 SOUNDPROOF PANELS DIMENSION: 250 X 125 CM WEIGHT CORE: ACM 17 / 965 KG/M5 CONSTRUCTION: 4-4-4/ 6-4-6/ 8-4-8/10-4-10/ 6-6-6/8-6-8/10-6-10 Kuiper Serene CR-900 - Rubberlight is a sandwich panel with a ACM 17 layer provided wit a top and bottom layer from okoume plywood. The ACM 17 is an engineerd cork and rubber composte material used to damp vibration before it is radiated as noise and before it is transmitted to other system components. Used as core material in constrained damping layer constructions (sandwich panels). Features: Non-hazardours, meets FMVSS302 fire resistance, Wear-resistant, low water absorption, good dimensional stability, non brittle, no mould growth. Compression Set - 50% def, RT(%)10 Thermal Resistivity (m°K/W)w 5.6 Glass Transition Temperature (Tg) (°C) - 71 Damping Layer Base Layer (Substrate) Constraining Layer Damping Layer CONSTRAINED-LAYER DAMPING During vibration distortion the system flexes creating sheer forces on the constrained layer. It is these shear forces that cause the energy to dissipate and turn into heat. Base Layer (Substrate) PANEL SURFACE WEIGHT Lightweight materials enable vehicles to reduce weight without reduction in size, load-carrying capacity and safety. It also allows the vehicle to acchieve higher speeds. When composite panels are used in the manufacture of such vehicles, the reduction of the panel surface weight is the most cost-effective mean to reduce fuel consumption and release of greenhouse gases to the atmosphere. In the transportation sector and considering that a bus utilize 25m2of composite panel. ACM 17 core material can reduce up to 115kg with an equivalent C02 saving of more than 240kg/ year (a). AIRBORNE SOUND ISOLATION VIBRATION DAMPING ACM 17 is a core material with a very good noise control performance at the mass controlled region and at the medium and high frequency region, while keeping a lower panel weight.
