一、概述玻璃纤维增强塑料,是一种新型各向异性结构材料,它具有质轻,高强度等多种优越性能。在近代工业,特别是在国防尖端工业上,得到了迅速发展和广泛的应用。由于玻璃钢今后越来越成为大型结构材料,故对于已成型的制品来说,与其基材破坏性检验比较,无损检验就显得十分重要了。所以就有必要研究有效的无损检验手段。
First, an overview Glass fiber reinforced plastic, is a new type of anisotropic structural materials, it has a light weight, high strength and many other superior properties. In modern industry, especially in the defense industry, it has been rapidly developed and widely used. As FRP becomes more and more a large structural material in the future, non-destructive testing becomes more and more important for formed products compared with the destructive testing of the substrate. Therefore, it is necessary to study effective non-destructive testing methods.
