本文的目的是证明一个简单但智能的超声脉冲回波技术作为复合材料处理器的质量保证工具的实用性。超声波脉冲回波技术应用于四个复合板;两个片材的每一种类型的玻璃纤维增强塑料，酚醛树脂和聚酯，在不同的加工条件下制造：一个是由正常的程序和其他故意的缺陷。实验在双盲测试方案下进行。在系统地分析数据并考虑光束发散效应后，我们能够确定材料的真实属性，从而轻松准确地区分缺陷和对照，同时定义所涉及的不同类型的缺陷。Polym.比较器：2010.© 2009年塑料工程师协会
The objective of this article is to demonstrate the practical usefulness of a simple but smart ultrasound pulse-echo technique as a quality assurance tool to composite processors. The ultrasound pulse-echo technique was applied to four composite slabs; two sheets for each type of fiberglass reinforced plastics, phenolic and polyester, manufactured under different processing conditions: one was made by the normal procedures and the other with deliberate flaws. The experiment was conducted under the double blind test protocol. After systematically analyzing the data and taking care of beam divergence effect, we are able to determine true properties of materials which allows to easily and accurately distinguish defects from controls and simultaneously define different types of defects involved.
