Conclusions

  1. 1.

    Increasing the wire diameter has a slight deleterious effect on the strength properties of materials fabricated from knitted gauzes.

     
  2. 2.

    With a material produced from unidirectionally arranged gauzes, the strength in the direction of loop rows is different from that in the direction of loop columns. The difference grows with increasing porosity. Cross stacking gives intermediate values of strength properties.

     
  3. 3.

    The directional anisotropy of the shear strength of the material may be employed as a characteristic of its porosity anisotropy.

     
  4. 4.

    Because of the continuity of its fibers the material possesses excellent ductility. In bending tests specimens with porosities greater than 70% are able to bend with-out cracking until their sides are parallel.

     
  5. 5.

    The material exhibits little notch sensitivity. Changing the radius of a stress raiser in the material from 1 to 0.1 mm has virtually no effect on its impact strength.
