For such applications an utmost impact strength is required in order to imple- .. increase of the composite's tensile strength compared to the pure PP reference

The results show a significant increase in tensile strength and elastic modulus with the amount of fiber. Increase in total deformation is observed above 10 vol%

strength of composites were also studied for both uniform and non-uniform fibre but then increases with increasing scatter of fibre strength when the yield

Ultimate tensile strength (UTS), often shortened to tensile strength (TS), ultimate strength, or Ftu in which the stress increases again with increasing strain, and they begin to neck, as the cross-sectional area of very high at 6,370 MPa, the UTS of a derived composite is 3,040 MPa – less than half the strength of the fiber.

groundwood fibers was improved by treating the fibers with 5% of sodium hydroxide, resulting in a noticeable increase of the tensile strength of the composites,

used as reinforcements for nylon-6.6 unidirectional composites. Improvement of fibers (12), led to an increase of up to 38.2% in tensile strength of Kevlar-.
