Quasi-static mechanical characterization and fatigue of a composite laminates

摘要

This present work focuses on the quasi- static mechanical characterization and or fatigue of a composite materialsud(laminate) jute/polyester manufactured under vacuum and with stacking sequences of 0/ 90. The obtained results ofudtensile tests on the laminate, showed a similar behavior on two levels: a linear portion up to 20 MPa and audnonlinear portion to rupture at 47 MPa σ max , followed by elongation of 2.08 % with a break elongation up toud2.50 %. Also, it was noted that increasing the temperature of the samples (5-6 ° C ) when the fatigue test remainsudin ISO 13003 , which requires a temperature increase of less than 10 ° C. the results of fatigue test showed also thatudwith a loading of 50% of the maximum load reached more than one million cycle, the more load is increasing theudcycle numbers of decreases
