摘要： The disclosure relates to pseudo porosity standards, and methods for their manufacture and use, which may substantially mimic the effect porosity has on ultrasonic sound as it passes through a composite laminate. An ultrasonic inspection reference standard for composite materials having porosity may include a member having at least one thickness and at least one discrete wire. The member may be manufactured from a fiber-free polymer resin using a stereo lithography process. The discrete wire may scatter and attenuate ultrasonic energy. The reference standard may replace more costly, porous, fiber-reinforced, composite reference standards in the aircraft industry and in other non-aircraft applications.

摘要： Ultrasonic measurements of porosity in manufactured parts or materials are calibrated using reference standards in which parallel holes are drilled in the backside of a body of material. The holes simulate voids in a part which attenuate incident ultrasonic energy. The number, size and location of the holes determine the simulated level of porosity that may be used to calibrate an ultrasonic tester. Multiple reference standards representing different levels of porosity can be produced in the form of individual coupons, or in a single body having multiple groups of holes.

摘要： An ultrasonic inspection reference standard for composite materials includes a prism that is manufactured from a polymer resin. The ultrasonic inspection reference standard may be a rectangular prism and may be a polymer resin step-wedge reference standard that has similar acoustic properties as prior art fiber-reinforced composite step-wedge reference standards at significantly lower manufacturing cost. A photo-polymer resin reference standard may be created using a stereo lithography process. The polymer resin reference standard may replace a currently used expensive fiber-reinforced composite reference standard. The ultrasonic inspection reference standard manufactured from a polymer resin may be used, for example, for ultrasonic inspection of fiber-reinforced composite parts. The polymer resin reference standard may be used, for example, in the aircraft airframe industry, both commercial and defense.
