Special Issue Information

Dear Colleagues,

Advances in the field of natural fiber composites have gained significant attention in recent years, and this Special Issue aims to showcase cutting-edge research and the latest developments in this area. Natural fibers have emerged as promising materials in the composites industry due to their excellent properties, such as renewability, biodegradability, and high specific strength. Furthermore, these materials have demonstrated remarkable potential across a wide range of applications due to their low environmental impact and cost-effectiveness.

The primary objective of this Special Issue is to provide a platform for academic exchange and present innovative research findings in the realm of natural fiber composites. We cordially invite experts and scholars engaged in relevant research to submit their manuscripts. The scope of this Special Issue encompasses, but is not limited to, the following:

  • Preparation, characterization, and performance evaluation of natural fiber composites;
  • Interface optimization and modification of natural fiber composites;
  • Novel reinforcement strategies for natural fiber composites;
  • Exploration of natural fiber-based functional materials for applications in filtration, separation, biomedical engineering, and other related fields.

Moreover, this Special Issue welcomes research articles and review papers that contribute to the advancement of knowledge in this rapidly evolving field. We encourage submissions that highlight the sustainability aspects of natural fiber composites, as well as their potential to replace conventional synthetic materials in various applications.

By publishing your valuable research findings in this Special Issue, you will have the opportunity to share your work with a global audience and contribute to the progress of natural fiber composites. We look forward to receiving your submissions and facilitating the dissemination of groundbreaking research in this exciting field.

Within this study, the impregnation behavior and resulting mechanical properties of unidirectional flax fiber-reinforced polyamide 11 biocomposites were investigated. Therefore, different grades of bio-based polyamide 11 have been evaluated regarding their eligibility as composite matrix material. The production of the unidirectional flax fiber-reinforced biocomposites was investigated using a continuous film-stacking method. It was found that the flow behavior of the polyamide 11 matrix polymer significantly affected the impregnation quality and the resulting mechanical properties as tested by tensile and bending tests. A lower shear viscosity and stronger shear thinning behavior led to better impregnation, a 15% higher stiffness, and 18% higher strength. This was also analyzed with morphological analysis by scanning electron microscopy. Additionally, the effect of the fiber volume content of the flax fibers on the mechanical properties was tested, showing a positive correlation between the fiber content and the resulting stiffness and strength, leading to an increase of 48% and 55%, respectively. In result, a maximum Young’s modulus of 16.9 GPa and tensile strength of 175 MPa at a fiber volume content of 33% was achieved. Thus, the unidirectional flax fiber-reinforced polyamide 11 biocomposites investigated can be a sustainable construction material for lightweight applications, e.g., in the automotive industry.
