Novel low cost, lightweight, sustainable biocomposites based on aligned jute sliver tape reinforcements (BioJUSTICE)

BioJUSTICE项目的目标是通过使用廉价的天然纤维和新颖的直接加工方法，开发低成本、轻量化、高性能的天然纤维生物复合材料。目前，半结构生物复合材料几乎完全基于相对昂贵的亚麻和需要几个加工步骤的编织纱线纺织品。这使得材料昂贵，难以证明许多工业应用的合理性。BioJUSTICE将使用低成本的黄麻纤维和直接的、基于胶带的制造方法，以最少的工艺步骤。新型黄麻胶带的成本和性能将与玻璃纤维相似，而且重量更轻，对环境的影响也更小。这将使可持续天然纤维首次真正与玻璃纤维竞争，显著提高其在建筑、汽车和体育等领域的应用。

The objective of the BioJUSTICE project is to develop low cost, lightweight, high performance natural fibre biocomposites by using inexpensive natural fibres and novel direct processing methods. Currently semi-structural biocomposites are almost exclusively based on flax which is relatively expensive, and woven yarn textiles which require several processing steps. This makes the materials expensive and difficult to justify for many industrial applications. BioJUSTICE will use low cost jute fibres and a direct, tape-based manufacturing method with minimum process steps. The new jute tapes will have similar cost and performance to glass fibres, along with lower weight and lower environmental impact. This will enable sustainable natural fibres to truly compete with glass fibres for the first time, significantly increasing their uptake in a range sectors including construction, automotive and sports.
