description

Tiek piedāvāts jauns koncepts tehniskā stāvokļa monitoringam (TSM) kompozītmateriāla elementiem. Koncepta realizācijai tika izstrādāta Bojājumu Vizuālās Indikācijas Sistēma (BVIS). Tā sastāv no auduma pamatnes, kas piesūcināta ar krāsvielu un krāsu aktivatoru mikrokapsulās. No pieliktās ārējas slodzes mikrokapsulas saplīst un saturs nonāk kontaktā, ķīmiskās reakcijas rezultātā notiek krāsu izmaiņa un slodzes vieta var tikt vizuāli identificēta. BVIS bija notestēts dažādiem pielietojumiem un tās izturība tika apstiprināta. Piedāvātais koncepts ļaus samazināt kompozītmateriālu tehniskā stāvokļa pārbaudes laiku, vienkāršos virsmu pārbaudi bez aparatūras. Šādi tiks paaugstināta ekspluatēšanas drošība un vienkāršots polimēru kompozītu TSM process. Bojājuma vizuālā indikācija, polimēra kompozīts, tehniskā stāvokļa monitorings, mikrokapsulas.
