摘要

植物纤维是替代合成纤维在聚合物基复合材料中的应用前景广阔。然而，仍然有一个重要的问题需要克服:纤维/基质界面的粘附质量差。已经开发了许多植物纤维的表面处理方法，其中大多数是基于非环境友好的工艺。本文提出了一种100%自然处理方法。大麻纱线浸泡在自来水中，直到附着在其表面的石灰石珠自然生长。形态学分析表明，这些碳酸钙晶体具有纳米针状结构，大麻纤维充当这些高度有序的珊瑚状结构的成核剂。对±45°编织麻/环氧复合材料的拉伸试验表明，CaCO3珠的存在改善了纤维/基体界面的粘附质量，从而提高了杨氏模量值。

The Natural Growth of CaCO3 Crystals on Hemp Yarns: A Morphology Analysis and the Mechanical Effects on Composites

Plant fibres are promising candidates to replace synthetic fibres in polymer matrix composites. However, there is still an important issue to overcome: the poor quality of adhesion at the fibre/matrix interface. Many surface treatments of plant fibres have been developed, most of them based on non-environmentally friendly processes. In this paper, a 100% natural treatment is proposed. Hemp yarns are immersed in tap water until the natural growth of limestone beads attached to their surface occurs. The morphology analysis reveals that these calcium carbonate crystals have a nanoneedle architecture, with hemp fibres acting as nucleators for these highly ordered coral-like structures. Tensile tests on ±45° woven hemp/epoxy composites show that the presence of CaCO3 beads improves the adhesion quality of the fibre/matrix interface and, therefore, increases Young’s modulus value.

期刊介绍： Fibers (ISSN 2079-6439) is a peer-reviewed scientific journal that publishes original articles, critical reviews, research notes and short communications on the materials science and all other empirical and theoretical studies of fibers, providing a forum for integrating fiber research across many disciplines. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files or software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. The following topics are relevant and within the scope of this journal: -textile fibers -natural fibers and biological microfibrils -metallic fibers -optic fibers -carbon fibers -silicon carbide fibers -fiberglass -mineral fibers -cellulose fibers -polymer fibers -microfibers, nanofibers and nanotubes -new processing methods for fibers -chemistry of fiber materials -physical properties of fibers -exposure to and toxicology of fibers -biokinetics of fibers -the diversity of fiber origins
