Abstract

ABSTRACT Advanced applications of polymer additive manufacturing (AM) require knowledge of the material acoustic and complex elastic properties. Recently, ultrasound nondestructive evaluation (NDE) methods have been applied to the understanding of AM polymers manufactured with a variety of methods. Nonetheless, the available information is still limited to a few materials and frequency ranges, and knowledge of shear acoustic properties and complex elastic properties of AM polymers is lacking. In this study, ultrasound measurements of compressional and shear phase velocity and attenuation are used to experimentally determine the complex elastic properties of 14 AM photopolymers manufactured using PolyJet systems. The results provided here are expected to aid in design of advanced polymer AM structures, and highlight the value of ultrasound NDE for the characterization of AM polymers.

增材制造光聚合物的超声无损评价

聚合物增材制造(AM)的高级应用需要材料声学和复杂弹性特性的知识。近年来，超声无损评价(NDE)方法已被应用于各种方法制造的AM聚合物的理解。尽管如此，可用的信息仍然局限于少数材料和频率范围，并且缺乏对AM聚合物的剪切声学特性和复杂弹性特性的了解。在这项研究中，超声测量的压缩和剪切相速度和衰减被用来实验确定14 AM光聚合物的复杂弹性性能使用PolyJet系统制造。本文提供的结果有望帮助设计先进的聚合物AM结构，并突出超声无损检测对AM聚合物表征的价值。

期刊介绍： Research in Nondestructive Evaluation® is the archival research journal of the American Society for Nondestructive Testing, Inc. RNDE® contains the results of original research in all areas of nondestructive evaluation (NDE). The journal covers experimental and theoretical investigations dealing with the scientific and engineering bases of NDE, its measurement and methodology, and a wide range of applications to materials and structures that relate to the entire life cycle, from manufacture to use and retirement. Illustrative topics include advances in the underlying science of acoustic, thermal, electrical, magnetic, optical and ionizing radiation techniques and their applications to NDE problems. These problems include the nondestructive characterization of a wide variety of material properties and their degradation in service, nonintrusive sensors for monitoring manufacturing and materials processes, new techniques and combinations of techniques for detecting and characterizing hidden discontinuities and distributed damage in materials, standardization concepts and quantitative approaches for advanced NDE techniques, and long-term continuous monitoring of structures and assemblies. Of particular interest is research which elucidates how to evaluate the effects of imperfect material condition, as quantified by nondestructive measurement, on the functional performance.
