复合材料行业产生大量各种形式的废物，从副产品的生产到报废部件。本文重点介绍了再制造的干纤维下脚料，在复合织物织造过程中产生的，高度对齐的不连续纤维预浸带与高性能不连续纤维（HiPerDiF）技术。单向层压板试样的制备使用各种组合的纤维长度和拉伸测试，获得80 GPa的刚度，800 MPa的强度，和1%的失效应变。设想了所生产的胶带的几种应用：粘合剂膜、长丝缠绕的原料和机织织物的丝束。这项工作证明了从目前被认为是制造业废物中提取价值的可能性。
The composites industry generates considerable volumes of waste in a wide variety of forms, from the production of by-products to end-of-life parts. This paper focuses on the remanufacturing of dry fibre off-cuts, produced during the composite fabric weaving process, into highly aligned discontinuous fibre prepreg tapes with High Performance Discontinuous Fibre (HiPerDiF) technology. Unidirectional laminate specimens are prepared using various combinations of fibre lengths and tested in tension, obtaining a stiffness of 80 GPa, a strength of 800 MPa, and a failure strain of 1%. Several applications are envisaged for the produced tape: adhesive film, feedstock for filament winding, and tow for weaved fabrics. This work demonstrates the possibility to extract value from what is currently considered manufacturing waste.
