THE MANNER OF PRODUCTION OF COMPOSITE WITH A SANDWICH PANEL STRUCTURE ON THE BASIS OF AEROGEL MAT, POLYURETHANE OR EPOXY RESIN MODIFIED WITH GLYCOLISATE OBTAINED ON THE BASIS OF WASTE POLYETHYLENE TEREPHTHALATE AND ENCAPSULATED PHASE CHANGE MATERIAL (PCM)

The manner of production of composite with a sandwich panel structure on the basis of aerogel mat and\ resin consists in the modification of resin with glycolisate obtained on the basis of waste polyethylene terephthalate and encapsulated phase change material (PCM), its hardening and adding encapsulated phase shift material to it. The aerogel mat surface is prepared by applying glass fibre veil soaked with a composition of modified resin with PET glycolisate in the amount of 10 weight %. The composition of modified resin with PET glycolisate is mixed with a glass rod in a glass or polypropylene recipient and it is heated during at least 30 minutes at the temperature of 70-90 degrees C. The hardener in the amount of 10 weight % of resin quantity is added to the modified resin. Encapsulated PCM has the phase shift temperature within the range of 21-25 degrees Celsius and it is bound using modified epoxy or polyurethane resin using the weight ratio of PCM/resin within the range of 0.6- 0.7.
