Tear strength and tensile strength of model filled elastomers
Journal of Polymer Science: Polymer Physics Edition, 1980 AbstractMeasurements have been made of the tear strength, tensile strength, and energy dissipated during stretching for model filled elastomers consisting of polybutadiene with glass beads incorporated. The glass beads were pretreated with various silanes, some of which could, in principle, form covalent bonds with the polybutadiene matrix during free ...

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

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.

Tear and Tensile Strength Development of PGW and CTMP Pulps Mixed With PLA or Viscose Fibres
Nordic Pulp and Paper Research Journal, 2014 The objective was to evaluate the effects on paper properties when replacing a minor share of wood fibre by synthetic fibre. The aim was to increase tear strength and stretch while minimizing the loss of tensile strength in paper consisting of mechanical

The fracture energy of moulded sheets of polyethylene has been found to depend strongly upon the thickness of the sheet, increasing linearly over the range 0.05 to 1.0 mm. This variation is attributed to a dependence of the volume of the plastic zone at the crack tip upont2, wheret is the torn thickness.

Tear strength of elastomeric impression materials
The Journal of Prosthetic Dentistry, 19781. Under simulated clinical conditions the maximum tear strength of those materials tested was reached in 10 to 15 minutes. 2. The polysulfide materials showed three to six times the tear strength of the silicones. 3. The polyether material displayed a tear resistance slightly higher than that of the silicones but one third to one fifth as high as that

Structural Parameters Affecting Tear Strength of the Fabrics Tents
AEJ - Alexandria Engineering Journal, 2018 The tearing strength is more vital in heavy duty fabrics. So it is important to know the effects of the fabric structural parameters on the tearing resistance of these types of fabrics.

Threshold tear strength of elastomers
Journal of Polymer Science: Polymer Physics Edition, 1982AbstractTear 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
