  2. Polycarbonate - Wikipedia

    en.wikipedia.org/wiki/Polycarbonate

    Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much higher impact-resistance. Polycarbonate lenses also protect the eye from UV light.

  3. Izod impact strength test - Wikipedia

    en.wikipedia.org/wiki/Izod_impact_strength_test

    Brittle materials have low toughness as a result of the small amount of plastic deformation they can endure at any rate. However, ductile materials may behave like brittle materials under high-energy impact, hence the need for this kind of test. The test conditions are governed by many variables, most importantly:

  4. 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 ...

  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. Fracture toughness - Wikipedia

    en.wikipedia.org/wiki/Fracture_toughness

    Cracks cannot easily propagate in tough materials, making metals highly resistant to cracking under stress and gives their stress–strain curve a large zone of plastic flow. Ceramics have a lower fracture toughness but show an exceptional improvement in the stress fracture that is attributed to their 1.5 orders of magnitude strength increase ...

  7. Relative thermal index - Wikipedia

    en.wikipedia.org/wiki/Relative_thermal_index

    A maximum correlation time of 60.000 hours is considered acceptable for many electrical applications, however it may also become as low as 5.000 hours according to UL 746B. If a material has not been investigated (yet), the RTI shown is based on the generic class (polymer type) of the material. Though the RTI is an index, it is given in Celsius ...

  8. Sheet moulding compound - Wikipedia

    en.wikipedia.org/wiki/Sheet_moulding_compound

    Sheet moulding compound (SMC) or sheet moulding composite is a ready to mould glass-fibre reinforced polyester material primarily used in compression moulding. [1] The sheet is provided in rolls weighing up to 1000 kg. Alternatively the resin and related materials may be mixed on site when a producer wants greater control over the chemistry and ...

  9. Siding (construction) - Wikipedia

    en.wikipedia.org/wiki/Siding_(construction)

    The environmental impact of masonry depends on the type of material used. In general, concrete and concrete based materials are intensive energy materials to produce. However, the long durability and minimal maintenance of masonry sidings mean that less energy is required over the life of the siding.
