Sehlopha sa bafuputsi ba National Renewable Energy Laboratory (NREL, Golden, Colo., US), ba etelletsoeng pele ke moenjiniere ea phahameng oa theknoloji ea moea oa NREL Derek Berry, ba ntse ba tsoela pele ho ntšetsa pele mekhoa ea bona e ncha ea ho etsa mahare a tsoetseng pele a turbine ea moea.ho ntlafatsa motsoako oa bonaea recyclable thermoplastics and additive production (AM).

Ho qala, sehlopha sa NREL se tsepamisitse maikutlo holim'a thepa ea matrix ea resin. Meralo ea hajoale e itšetleha ka lits'ebetso tsa thermoset resin joalo ka li-epoxies, polyesters le vinyl esters, lipolymer tseo, ha li se li phekotsoe, li hokahanya joalo ka marikhoe.

"Hang ha o hlahisa lehare le nang le thermoset resin system, o ke ke oa etsolla ts'ebetso ena," ho bolela Berry. "Seo [hape] se etsa lehareho thata ho botjha.”

Ho sebetsa leSetsi sa Boiqapelo ba Tlhahiso e Tsoetseng Pele ea Likopano(IACMI, Knoxville, Tenn., US) Setsing sa NREL's Composites Manufacturing Education and Technology (CoMET) Setsi, sehlopha sa mekhatlo e mengata se ile sa hlahisa mekhoa e sebelisang thermoplastics, eo, ho fapana le thepa ea thermoset, e ka futhumatsang ho arola li-polymers tsa pele, tse nolofalletsang ho fela. -of-life (EOL) recyclability.

"Ka likarolo tse peli tsa lehare la thermoplastic, u na le bokhoni ba ho li kopanya 'me, ka ho sebelisa mocheso le khatello, li kopane le tsona," Berry o re. "U ke ke ua etsa joalo ka lisebelisoa tsa thermoset."
