自动纤维铺放（AFP）是一种用于制造具有定制纤维路径的可变角度丝束（VAT）复合材料的尖端技术。然而，其工艺缺陷阻碍了VAT复合材料结构的广泛应用。作为一种替代的制造方法，连续丝束剪切（CTS）技术，利用剪切干丝束的能力，已经开发出来。结果表明，CTS可以显着减少工艺引起的缺陷，如纤维缠结，树脂丰富的地区和纤维不连续。在本文中，它的制造特性，如材料特性，铺层精度，和厚度变化进行了实验研究。(C)2014爱思唯尔有限公司版权所有。
Automated fibre placement (AFP) is well-known as a cutting-edge technology for manufacturing variable angle tow (VAT) composites with tailored fibre paths. However, its process-induced defects prevent the wide application of VAT composite structures. As an alternative manufacturing method, the continuous tow shearing (CTS) technique, utilising the ability to shear dry tows, has been developed. It was shown that CTS could significantly reduce process-induced defects such as fibre wrinkling, resin rich areas and fibre discontinuities. In this paper, its manufacturing characteristics such as material characteristics, layup accuracy, and thickness variation are investigated experimentally.(C) 2014 Elsevier Ltd. All rights reserved.
