n this research, the unsaturated polyester resin (polylite

420-852) is used in combination with bidirectional jute

ber to generate composites materials by a contact molding

technique. The parameter which was carried out on the

prepared samples was impact test to plot the S-N curve,

which is based on Wöhler equation. Two-parameter Weibull

probability was used for analysis statistically the fatigue

life results of composite jute/polyester samples. Weibull

graphic was plotted for each loading level using fatigue

data. Then, S–N curves were drawn for different reliability

levels (Ps=99%, Ps=90%, Ps=50%, Ps=36.8% and Ps=10%)

using Weibull data. These S-N curves were introduced to the

identification of the first failure time as reliability and safety

limits of the material.
