Abstract
In this work, we investigate the thermomechanical behavior of flax-fabric/epoxy composites by means of DMA experiments. Fabrics from flax fibers have undergone different chemical treatments: leaching, bleaching or mercerization. We study the influence of these chemical treatments on the dynamic mechanical relaxation spectra of the composites around the main relaxation mode. We construct master plots for the loss modulus for each sample using the time-temperature superposition (TTS) principle. The master curves were fitted with the Havriliak-Negami model and we show that both interface and interphase of composites are modified as a result of the chemical treatments. Best mechanical properties were found for mercerized treatment.
