3. Twinwall plastic - Wikipedia

   en.wikipedia.org/wiki/Twinwall_plastic

   Although single layer polycarbonate sheeting is more flexible than polycarbonate in twinwall configuration, it still retains significant advantages over alternative materials, including glass. A typical 6mm sheet has a density of 0.72 g/cm^2 [6] and a thermal insulation R value of 0.3 m^2°C/W, while allowing 80% of visible light pass through. [7]

4. Izod impact strength test - Wikipedia

   en.wikipedia.org/wiki/Izod_impact_strength_test

   Scheme for the determination of Izod impact strength test results. Impact, by definition, is a large force applied for a very short time, resulting in a sudden transfer of momentum and energy, and its effect is different when the same amount of energy is transferred more gradually. Everyday engineering structures are subjected to it and may ...

5. Plastics in the construction industry - Wikipedia

   Below are some uses for plastics in the construction industry: Pipes for rain water, sewage, gas distribution, and organizing wires may be made of plastic. Cable insulation and insulating tape is usually made of plastic. Plastic may be used in flooring and roofing materials. Doors, window panels, and skylights may be made of plastic.

6. Notch (engineering) - Wikipedia

   en.wikipedia.org/wiki/Notch_(engineering)

   The most common is the Charpy impact test, which uses a pendulum hammer (striker) to strike a horizontal notched specimen. The height of its subsequent swing-through is used to determine the energy absorbed during fracture. The Izod impact strength test uses a circular notched vertical specimen in a cantilever configuration. Charpy testing is ...

7. Charpy impact test - Wikipedia

   en.wikipedia.org/wiki/Charpy_impact_test

   Impact tests on natural materials (can be considered as low-strength), such as wood, are used to study the material toughness and are subjected to a number of issues that include the interaction between the pendulum and a specimen as well as higher modes of vibration and multiple contacts between pendulum tup and the specimen.

8. Glass-filled polymer - Wikipedia

   en.wikipedia.org/wiki/Glass-filled_polymer

   As the fibres were only short this material had relatively low bulk strength, but still improved surface hardness and good mouldability. A wide range of polymers are now produced in glass-filled varieties, including polyamide (Nylon), acetal homopolymers and copolymers , polyester , polyphenylene oxide (PPO / Noryl ), polycarbonate ...
