| Summary: | Typha is a fast-growing and invasive plant that spreads in the humid areas. Its proliferation has a negative impact on the local ecosystems. This study aims at the valorization of the by-products of this plant as biocomposites’ reinforcements. A mechanical extraction technique and retting in distilled water and sea water processes were developed to extract fibers from the leaves and stems of the Typha plants. SEM, FTIR analyses and monotonic tensile tests have been carried out to assess fibers’ properties. Morphological observations revealed that fibers extracted from the leaves were on average 48% finer than those from the stems. This fineness was more significant for the fibers retted in distilled water, that presented a smoother surface. The leaf fibers tensile properties (502, 247 and 372 MPa for the strength, 20.5, 14.2 and 12.8 GPa for the Young’s modulus and 2.47, 1.68 and 2.73% for maximum strain, respectively for the mechanical, distilled water and sea water retting processes) were on average 50% higher than for stem fibers, regardless of the extraction method. The results showed that the fibers elaborated had promising properties for biocomposite reinforcement. The extraction methods developed are low cost and without the use and generation of polluting chemicals |
