a. Yield Yield is a measurement of the strand length per unit weight. Its units are yards/pound (ypp).
b. 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.
c. Breakage Strength Breakage strength refers to the point at which the specimen will break from applied stress.
d. Moisture Content (Loss On Ignition, LOI) Moisture Content is defined as the percentage of water in a fiberglass product.
e. Combustible Content Combustible Content is defined as the percentage of combustible in a fiberglass product which is expressed by %. .
f. Area Weight Area Weight is defined as the weight per unit area of tape or fabric. Typical units are g/cm^{2}, g/m^{2}, ounces/foot^{2}, and^{ }ounces/yard^{2}.
g. Tensile Strength The maximum tensile stress sustained by a plastic specimen before it fails in a tension (a pulling force) test.
h. Flexural Strength Flexural Strength is defined as the maximum stress the material will withstand in bending at the moment of rupture.
i. 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.
j. 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. |
