2. 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 ...

3. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   Polycarbonate is a durable material. Although it has high impact-resistance, it has low scratch-resistance. Therefore, a hard coating is applied to polycarbonate eyewear lenses and polycarbonate exterior automotive components.

4. Acrylonitrile styrene acrylate - Wikipedia

   en.wikipedia.org/wiki/Acrylonitrile_styrene_acrylate

   It has good chemical and heat resistance, high gloss, good antistatic properties, and is tough and rigid. It is used in applications requiring weatherability, e.g. commercial siding, outside parts of vehicles, or outdoor furniture. [4] ASA is compatible with some other plastics, namely polyvinyl chloride and polycarbonate. ASA-PVC compounds are ...

5. Strength of materials - Wikipedia

   en.wikipedia.org/wiki/Strength_of_materials

   The strength of materials is determined using various methods of calculating the stresses and strains in structural members, such as beams, columns, and shafts. The methods employed to predict the response of a structure under loading and its susceptibility to various failure modes takes into account the properties of the materials such as its yield strength, ultimate strength, Young's modulus ...

6. Charpy impact test - Wikipedia

   en.wikipedia.org/wiki/Charpy_impact_test

   The impact energies of high-strength materials other than steels or BCC transition metals are usually insensitive to temperature. High-strength BCC steels display a wider variation of impact energy than high-strength metal that do not have a BCC structure because steels undergo microscopic ductile-brittle transition. Regardless, the maximum ...

7. Relative thermal index - Wikipedia

   en.wikipedia.org/wiki/Relative_thermal_index

   For a full study, the candidate material (B) is aged together with a reference material A (control) with already known RTI value in the same ovens. The RTI is the rounded temperature in degrees C , at which the properties of B have decreased to 50 percent of their initial value in about the same amount of time (correlation time) than it takes ...

8. Twinwall plastic - Wikipedia

   en.wikipedia.org/wiki/Twinwall_plastic

   Twin-wall plastic, specifically twin-wall polycarbonate, is an extruded multi-wall polymer product created for applications where its strength, thermally insulative properties, and moderate cost are ideal. [1] Polycarbonate, which is most commonly formed through the reaction of Bisphenol A and Carbonyl Chloride, is an extremely versatile ...

9. Engineering plastic - Wikipedia

   en.wikipedia.org/wiki/Engineering_plastic

   The currently most-consumed engineering plastic is acrylonitrile butadiene styrene (ABS), used for e.g. car bumpers, dashboard trim and Lego bricks. Engineering plastics have gradually replaced traditional engineering materials such as metal, glass or ceramics in many applications. Besides equalling or surpassing them in strength, weight, and ...
