Vedno bolj pomembno je recikliranje in krožno gospodarstvo ter s tem zmanjšanje pritiska na naravne vire, ustvarjanje trajnostne rasti in zaustavitev izgube biotske raznolikosti. S tem ciljem v mislih, je Evropska Unija sprejela akcijski načrt, katerega del je tudi projekt START CIRCLES. V povezavi s podjetjem M Sora, smo v okviru tega projekta izdelali inovativni hibridni material z imenom »Comet«, ki naj bi se uporabljal v pod okenski odprtini za preprečevanje toplotnega mostu. Za izdelavo smo uporabili odpadne materiale iz proizvodnje lesenih oken – les in steklo ter jih povezali s taninom in poliuretansko matrico. Raziskavo smo zastavili tako, da smo spreminjali le eno spremenljivko naenkrat in opazovali vpliv na fizikalne in mehanske lastnosti izdelanega kompozita. Spreminjali smo deleže PU, tanina, stekla, gostoto, velikost gradnikov in različne deleže določenih velikosti gradnikov. Za vsako izdelano ploščo smo določali lastnosti, ki so najbolj pomembne za ciljno uporabo – gostota, tlačna trdnost (pri 10 % deformaciji), toplotna prevodnost in upogibna trdnost. V vsakem koraku smo določili vzorec z najboljšimi lastnostmi in jo uporabili v nadaljnjih preizkusih. Na tak način smo prišli do končnih vzorcev, ki smo jih nato primerjali z materiali, ki so že na trgu in se v praksi uporabljajo v pod okenski odprtini. Glede na lastnosti, ki smo jih izmerili, smo prišli do zaključka, da je izdelan material primeren za uporabo v pod okenski odprtini.

• Title: Innovative hybrid composites from window production residues

Abstract

Recycling and the circular economy are becoming increasingly important for reducing the pressure on natural resources, creating sustainable growth and halting the loss of biotic diversity. With this goal in mind, the European Union put in motion an action plan which includes the START CIRCLES project. In connection with the company M Sora, within the framework of this project, an innovative hybrid composite material, called “Comet”, was created. It was meant for use under windows to prevent thermal bridges. Waste materials from window production were used, namely wood and glass, which we bonded with tannin and polyurethane matrix. The research was set in such a way that it was possible to change one variable at a time and observe it's impact on the physical and mechanical properties of the composite. We altered the proportions of PU, tannin, glass and changed the density, wood particle size and the proportions of each size of wood particles. For each manufactured panel, we determined the properties that are the most important for the intended use – density, compressive strength (at 10 % deformation), thermal conductivity and flexural strength. In each step we determined the sample with the best properties and used that for further testing. Using such a procedure, we arrived at the final samples, which we then compared with materials that are already on the market and are being used in practice. Based on the properties we measured, we came to the conclusion that the manufactured material is suitable for use under windows.
