2. Twinwall plastic - Wikipedia

   en.wikipedia.org/wiki/Twinwall_plastic

   Twin-wall polycarbonate is able to flex in the demanding conditions of four-season greenhouses and allows for consistent temperature management because of the insulative properties. [ 12 ] Twinwall Polycarbonate sheeting is primarily installed with glazing bars, which secure the sheets down to the frame, whether timber, metal or other framing ...

3. Polycarbonate - Wikipedia

   extrusion with cylinders into sheets (0.5–20 mm (0.020–0.787 in)) and films (below 1 mm (0.039 in)), which can be used directly or manufactured into other shapes using thermoforming or secondary fabrication techniques, such as bending, drilling, or routing. Due to its chemical properties it is not conducive to laser-cutting.

4. Liquid-crystal polymer - Wikipedia

   en.wikipedia.org/wiki/Liquid-crystal_polymer

   If the volume fraction of the polymers exceeds the critical volume fraction, the micellar segregates will be packed to form a liquid crystal structure. As the concentration varies above the critical volume fraction, the liquid crystal generated may be packed in different structures.

5. Wall panel - Wikipedia

   en.wikipedia.org/wiki/Wall_panel

   While there is no set size limit for a piece of material fulfilling these functions, the maximum practical size for wall panels has been suggested to be about 0.6 to 2.4 m (2 to 8 ft), to allow for transportation. [1] Decorative wall panels are also known as charcoal wall panels, PVC wall panels, WPC wall panels, charcoal louver panels, PVC ...

6. Fracture toughness - Wikipedia

   en.wikipedia.org/wiki/Fracture_toughness

   For example, according to ASTM E399, the maximum stress intensity K max should be no larger than 0.6 during the initial stage and less than 0.8 when crack approaches its final size. [ 14 ] In certain cases grooves are machined into the sides of a fracture toughness specimen so that the thickness of the specimen is reduced to a minimum of 80% of ...
