High tear strength polyurea foams with low compression set and shrinkage properties at elevated temperatures

International Journal of Mechanical Sciences, 2019
The mechanical properties of low-density polyurea (PU) foams (150–300 kg/m3) are presented. The hardness, tensile strength, elongation, compression set, resilience, tear strength, and shrinkage were investigated according to the American Society for ...

Threshold tear strength of elastomers

Journal of Polymer Science: Polymer Physics Edition, 1982
AbstractTear strengths have been measured for a wide variety of molecular networks under threshold conditions; i.e., at high temperatures, low rates of tearing, and with swollen samples. For all of the polymers examined, the threshold tear strength was found to be proportional to the square root of the average molecular weight Mc of network strands, in

Tear Strength of Stretched Rubber

Rubber Chemistry and Technology, 1978
Abstract Highly stretched rubber sheets can be split apart quite easily, indicating that the originally isotropic material becomes “fibrous” in character—i.e., much weaker for a tear running in the direction of extension than for one running at right angles to it. This anisotropy of strength is shown most clearly by elastomers which crystallize

Prediction of tear strength of bed sheet fabric using machine learning based artificial neural network

Journal of the Textile Institute, 2022
Fabric tear strength is an important parameter in textile materials since it is linked to the fabric’s life. When it comes to bed sheets, a consumer’s main concerns are mechanical comfort and durability.

Analysis of Tear Strength

Textile Research Journal, 1947
An analysis has been made of the factors involved in the A.S.T.M. Trapezoid Tear-Strength Test. The tear strength of a fabric measured by this test is dependent mainly on the extensibility of the threads, the breaking strength of the threads, the effective specimen length, and the number of threads per inch of fabric.
