2. Acoustic foam - Wikipedia

   en.wikipedia.org/wiki/Acoustic_foam

   Acoustic foam is a lightweight material made from polyurethane (either polyether or polyester) or extruded melamine foam. [8] It is usually cut into tiles. One surface of these tiles often features pyramid, cone, wedge, or uneven cuboid shapes. Acoustic foam tiles are suited to placing on sonically reflective surfaces to act as sound absorbers ...

3. Bracket (architecture) - Wikipedia

   Depending on their material, decorated ones can be carved, cast, or molded. They can be of cast stone or resin-foam materials with faux finishes for use on new buildings in historic revival styles of architecture. Some brackets and corbels are only ornamental, and serve no actual supporting purpose. [4] [5]

4. Aluminium foam sandwich - Wikipedia

   en.wikipedia.org/wiki/Aluminium_foam_sandwich

   Aluminium foam sandwich (AFS) is a sandwich panel product which is made of two metallic dense face sheets and a metal foam core made of an aluminium alloy. AFS is an engineering structural material owing to its stiffness-to-mass ratio and energy absorption capacity ideal for application such as the shell of a high-speed train .

5. Sandwich-structured composite - Wikipedia

   en.wikipedia.org/wiki/Sandwich-structured_composite

   Sandwich structures can be widely used in sandwich panels, with different types such as FRP sandwich panel, aluminium composite panel, etc. FRP polyester reinforced composite honeycomb panel (sandwich panel) is made of polyester reinforced plastic, multi-axial high-strength glass fiber and PP honeycomb panel in special antiskid tread pattern ...

6. Sandwich panel - Wikipedia

   en.wikipedia.org/wiki/Sandwich_panel

   The density of sandwich panels range from 10 kg/m 2 up to 35 kg/m 2, depending on the foam and metal thickness, decreasing time and effort in: transportation, handling and installation. All these geometric and material properties influence the global/local failure behavior of the sandwich panels under different loading conditions such as ...

7. Building insulation material - Wikipedia

   en.wikipedia.org/wiki/Building_insulation_material

   Insulation may be categorized by its composition (natural or synthetic materials), form (batts, blankets, loose-fill, spray foam, and panels), structural contribution (insulating concrete forms, structured panels, and straw bales), functional mode (conductive, radiative, convective), resistance to heat transfer, environmental impacts, and more.
