Zylon is used by NASA in long-duration, high-altitude data collection. Braided Zylon strands maintain the structure of polyethylene superpressure balloons. Zylon is the material of choice due to its low weight, high tensile strength, and thermal properties. [21]
This concluded that water, long-term use, and temperature exposure significantly affect tensile strength and the ballistic performance of PBO or Zylon fiber. This NIJ study on vests returned from the field demonstrated that environmental effects on Zylon resulted in ballistic failures under standard test conditions. [15]
Ultimate tensile strength of the polymer Zylon: 10 10 Pa. 10 GPa Pressure at which octaoxygen forms at room temperature (100,000 bar) [81] 18 GPa
The properties of Zytel will vary with the specific formulation. Formulation Zytel HTN 35% Glass Reinforced Resin, consisting of 35% glass fibre by weight, has a tensile strength of around 30kpsi and a flexural modulus of 1500kpsi under room temperature conditions.
It is also known as the strength-to-weight ratio or strength/weight ratio or strength-to-mass ratio. In fiber or textile applications, tenacity is the usual measure of specific strength. The SI unit for specific strength is Pa ⋅ m 3 / kg , or N ⋅m/kg, which is dimensionally equivalent to m 2 /s 2 , though the latter form is rarely used.
This concluded that water, long-term use, and temperature exposure significantly affect tensile strength and the ballistic performance of PBO or Zylon fiber. This NIJ study on vests returned from the field demonstrated that environmental effects on Zylon resulted in ballistic failures under standard test conditions. [43]
Inert, thermally stable, tough and high tensile strength: Bottles, pipes, inner insulation (dielectric) of coax cable (see also PTFE), plastic bags, etc. Polypropylene: PP: Resistant to acids and alkalies, High tensile strength: Auto parts, industrial fibers, food containers, liner in bags, dishware and as a wrapping material for textiles and food
Adsorption by enzymatic digestion and starts losing tensile strength on implantation from 18–21 days of catgut chromic: Adsorption by hydrolysis complete between 60 and 90 days. Always predictable and reliable: Wound support can remain up to 42 days, however tensile strength decreases to about 70% at 14 days and 25% at 42 days Tissue reaction ...
