摘      要：This work aims at studying the effect of hygrothermal and UV cyclic aging on the tensile properties and esthetic characteristics of non-woven *** composite materials were thermo-compressed from non-woven mats made up of PP and flax or kenaf *** works included evaluating the change in color appearance and analyzing the variations in tensile properties and damage mechanisms,depending on the aging *** presence of the UV protection film on the composite surface showed its effectiveness against *** visual observations and measurement of colorimetric parameters,it has been proved effective in the reduction of the bleaching and yellowing of the *** regards the tensile tests,the UV protection film enabled to stabilize the Young’s modulus after 1-week aging for Kenaf/PP and after 3-weeks for Flax/*** 4-weeks aging,it halved the number of acoustic emission events related to interfacial decohesion and fiber slippage/pull out for Flax/PP and Kenaf/PP composites.
