Methods we focused on this week were Eddy currents and capacitance. A paint thickness gauge, which is highly used in the automotive industry to measure the thickness of the paint of the outer body, was used to measure eddy currents to calculate the thickness on our test samples. From the experiment, we were able to see a noticeable difference between the thickness of the non-defect section to the defect section on both unidirectional and woven carbon fiber prepreg.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.ippd.ufl.edu\/blogs\/ay2223team14\/wp-content\/uploads\/sites\/126\/2022\/10\/Paint-Thickness-Gauge-Test-766x1024.jpg\" alt=\"\" class=\"wp-image-1146\" width=\"287\" height=\"384\" srcset=\"https:\/\/www.ippd.ufl.edu\/blogs\/ay2223team14\/wp-content\/uploads\/sites\/126\/2022\/10\/Paint-Thickness-Gauge-Test-766x1024.jpg 766w, https:\/\/www.ippd.ufl.edu\/blogs\/ay2223team14\/wp-content\/uploads\/sites\/126\/2022\/10\/Paint-Thickness-Gauge-Test-224x300.jpg 224w, https:\/\/www.ippd.ufl.edu\/blogs\/ay2223team14\/wp-content\/uploads\/sites\/126\/2022\/10\/Paint-Thickness-Gauge-Test-768x1027.jpg 768w, https:\/\/www.ippd.ufl.edu\/blogs\/ay2223team14\/wp-content\/uploads\/sites\/126\/2022\/10\/Paint-Thickness-Gauge-Test-1149x1536.jpg 1149w, https:\/\/www.ippd.ufl.edu\/blogs\/ay2223team14\/wp-content\/uploads\/sites\/126\/2022\/10\/Paint-Thickness-Gauge-Test-1532x2048.jpg 1532w, https:\/\/www.ippd.ufl.edu\/blogs\/ay2223team14\/wp-content\/uploads\/sites\/126\/2022\/10\/Paint-Thickness-Gauge-Test-157x210.jpg 157w, https:\/\/www.ippd.ufl.edu\/blogs\/ay2223team14\/wp-content\/uploads\/sites\/126\/2022\/10\/Paint-Thickness-Gauge-Test-scaled.jpg 1915w\" sizes=\"(max-width: 287px) 100vw, 287px\" \/><figcaption>Testing samples using a paint thickness gauge<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-2 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-video\"><video controls loop src=\"https:\/\/www.ippd.ufl.edu\/blogs\/ay2223team14\/wp-content\/uploads\/sites\/126\/2022\/10\/Colpitts-Circuit.mp4\" playsinline><\/video><figcaption>Colpitts oscillator with RC oscillator<\/figcaption><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p>To improve our capacitance measurement method that we have been testing for the past few weeks, we refined the circuit to include a Colpitts oscillator in addition to the RC oscillator.
