Correlation between accelerated aging and natural aging of a bio-sourced flax fiber/unsaturated polyester composite

International audienceAccelerated aging tests were carried out on flax fibers, unsaturated polyester and the composite combining these two constituents in order to study their degradation mechanisms. From these tests correlations were derived between the behavior of the composite and those of its constituents under different hydrothermal conditions. The results indicate that accelerated aging tests parameters used for synthetic fiber composites are not always suitable for studying the natural aging of plant fiber composites
