Abstract

The surface of a unidirectional carbon tape has been coated by two types of metal coatings (copper and zinc) by a magnetron sputtering technique. The strength of elementary carbon fibers with these metal coatings and interlaminar shear strength of carbon plastics based on them are evaluated. The carbon plastics with epoxy binder are produced via a vacuum infusion technique. It is found that copper coating allows one to increase strength of elementary fibers on 15–22% and leads to similar rise in interlaminar shear strength of carbon plastics. To the contrary, zinc coating deteriorates strength of the elementary carbon fibers and composites based on them. The results of structural analysis of the elementary carbon fibers with metal coatings are given, and their thicknesses after long-term storage of the metallized carbon tapes are determined.

铜锌涂层对碳纤维及其复合材料性能的影响

摘要

单向碳带的表面已通过磁控溅射技术被两种类型的金属涂层（铜和锌）覆盖。对具有这些金属涂层的基本碳纤维的强度和基于它们的碳塑料的层间剪切强度进行了评估。带有环氧粘合剂的碳塑料是通过真空灌注技术生产的。发现铜涂层可以使基本纤维的强度提高15-22％，并导致碳塑料的层间剪切强度得到类似的提高。相反，镀锌会使单质碳纤维和基于它们的复合材料的强度下降。给出了具有金属涂层的基本碳纤维的结构分析结果，并确定了长期存放金属化碳带后的厚度。
