Polimēru matricas sfēriskas pildvielas mehānisko īpašību noteikšana netiešā veidā

subject

Elastības modulis Stiepe Maisījuma likums Fizika Mikrokapsulas PVA līme

description

Polimēru kompozītmateriālam tiek realizēta funkcija mehānisko bojājumu indicēšanai ar vizualizācijas paņēmienu, kurai nepieciešams novērtēt komponenšu fizikālās īpašības. Pamata komponente vizualizēšanas procesā ir mikrokapsulas, kurām elastības moduli ir iespējams noteikt tiešā un netiešā veidā. Tiešā veidā pildvielu elastības moduļa noteikšanai, kad pildviela ir mikro izmēra, ir nepieciešama specifiska aparatūra, bet, lai iegūtu sākuma informāciju un priekšstatu par materiālu, pietiek ar mērīšanu netiešā veidā. Darba mērķis¬¬¬¬¬ ir pēc stiepes eksperimenta datiem noteikt mikrokapsulu elastības moduli netiešā veidā. Kā matrica tika izvēlēta PVA līme. Paraugu fizikālo īpašību noteikšanai, bija veikti stiepes eksperimenti un iegūts kompozīta elastības modulis. No iegūtiem datiem ar maisījuma likumu novērtē mikrokapsulu elastības moduli.
