  • Shear Strength

    Shear Strength is defined as the value of shear stress, which causes contiguous parts of a body to slide with respect to each other in a direction parallel to their plane of contact, reached when the material ruptures.

  • Compressive Strength

    Compressive Strength is defined as the value of uniaxial compressive stress reached when the materials fails completely. 
    Compressive Strength is a key mechanical parameter, representing the material’s ability to resist deformation under load.
  • Flexural Strength

    Flexural Strength is defined as the maximum stress the material will withstand in bending at the moment of rupture.

  • Tensile Strength

    The maximum tensile stress sustained by a plastic specimen before it fails in a tension (a pulling force) test.

  • Area Weight

    Area Weight is defined as the weight per unit area of tape or fabric. Typical units are g/cm2, g/m2, ounces/foot2, and ounces/yard2.

  • Combustible Content

    Combustible Content is defined as the percentage of combustible in a fiberglass product which is expressed by %. .

  • Moisture Content

    Moisture Content is defined as the percentage of water in a fiberglass product.

  • Breakage Strength

    Breakage strength refers to the point at which the specimen will break from applied stress.

  • Linear Density

    Liner density is defined in term of the weight per unit length. Its unit is tex, which is equal to the mass in grams of 1 km of yarn, filament, fiber or other textile strand.
  • Yield

    Yield is a measurement of the strand length per unit weight. Its units are yards/pound (ypp).
