Unsaturated polyester resin yog ib qho thermosetting resin, uas tuaj yeem ua kom muaj zog rau hauv cov khoom siv hluav taws xob tsis sib xws hauv cov khoom siv hluav taws xob los yog cov khoom siv hluav taws xob. Nyob rau hauv qhov kev txiav txim ntawm kev ntxhov siab, cov hlau feem ntau muab faib ua ob theem: elastic deformation thiab yas deformation.
Nyob rau hauv qhov kev txiav txim ntawm kev ntxhov siab, UPGM203 feem ntau tsis muaj qhov tseem ceeb ntawm cov yas deformation theem, tsis muaj qhov taw tes tawm, delamination nyob rau hauv cov txheej txheem ntawm kev ntxhov siab, thiab yog ib qho yooj yim tawg tam sim ntawd nyob rau hauv overload. Qhov thib ob, lub modulus ntawm UPGM203 yog tsawg, uas yog 10 lub sij hawm phem tshaj cov hlau. Yog li ntawd, cov khoom uas muaj rigidity siab yuav tsum tau ua tib zoo tsim. Thib peb, qhov kub tsis kam ntawm UPGM203 yog qhov sib txawv ntawm cov khoom siv hlau. Txog tam sim no, qhov kev pabcuam mus sij hawm ntev ntawm UPGM203 tsuas yog chav F.
