  2. Ultra-high-molecular-weight polyethylene - Wikipedia

    en.wikipedia.org/wiki/Ultra-high-molecular...

    LIROS Dyneema hollow. Dyneema and Spectra are brands of lightweight high-strength oriented-strand gels spun through a spinneret. They have yield strengths as high as 2.4 GPa (350,000 psi) and density as low as 0.97 g/mL (0.035 lb/cu in) (for Dyneema SK75). [12]

  3. Dyneema Composite Fabric - Wikipedia

    en.wikipedia.org/wiki/Dyneema_Composite_Fabric

    Dyneema Composite Fabric (DCF), also known as Cuben Fiber (CTF3), is a high-performance non-woven composite material used in high-strength, low-weight applications. It is constructed from a thin sheet of ultra-high-molecular-weight polyethylene ( UHMWPE , "Dyneema") laminated between two sheets of polyester .

  4. Specific modulus - Wikipedia

    en.wikipedia.org/wiki/Specific_modulus

    To emphasize the point, consider the issue of choosing a material for building an airplane. Aluminum seems obvious because it is "lighter" than steel, but steel is stronger than aluminum, so one could imagine using thinner steel components to save weight without sacrificing (tensile) strength.

  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. Specific strength - Wikipedia

    en.wikipedia.org/wiki/Specific_strength

    The specific strength is bounded to be no greater than c 2 ≈ 9 × 10 13 kN⋅m/kg, where c is the speed of light. This limit is achieved by electric and magnetic field lines, QCD flux tubes , and the fundamental strings hypothesized by string theory .

  7. Kevlar - Wikipedia

    en.wikipedia.org/wiki/Kevlar

    Kevlar (para-aramid) [2] is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora.Developed by Stephanie Kwolek at DuPont in 1965, [3] [2] [4] the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires.

  8. Work hardening - Wikipedia

    en.wikipedia.org/wiki/Work_hardening

    An example of undesirable work hardening is during machining when early passes of a cutter inadvertently work-harden the workpiece surface, causing damage to the cutter during the later passes. Certain alloys are more prone to this than others; superalloys such as Inconel require materials science machining strategies that take it into account.

  9. Webbing - Wikipedia

    en.wikipedia.org/wiki/Webbing

    Webbing is less likely to loosen itself off the rock than tubular rope. Note that webbing construction is either utterly flat or flat-tubular; the latter tends to handle better but knots are more likely to jam. The most popular knots in webbing are the water knot and the grapevine knot. The latter is stronger, but uses more webbing for the knot.
