Cov ntawv sib xyaw uas cov khoom siv hluavtaws siv los ua cov khoom siv matrix. Raws li qhov sib txawv matrix resin siv, nws tuaj yeem muab faib ua epoxy resin, unsaturated polyester resin, phenolic resin thiab lwm yam. Epoxy resin yog tus cwj pwm los ntawm siab compression thiab tensile lub zog. Nws tseem tuaj yeem tuav cov khoom siv kho tshuab zoo nyob rau hauv qhov kub thiab txias rau lub sijhawm ntev. Nws muaj qhov zoo arc tsis kam, UV aging kuj thiab huab cua tsis kam. Unsaturated resin yog tus cwj pwm los ntawm lub teeb yuag, siab zog, zoo corrosion kuj, zoo hluav taws xob kev ua tau zoo, tshwj xeeb thermal kev ua tau zoo, kev ua haujlwm zoo heev thiab cov khoom tsim tau zoo.
Qhov tsis zoo ntawm epoxy resin yog tus nqi siab, uas yog ntau tshaj ob zaug ntawm unsaturated polyester resin, thiab lub sij hawm kho yog ntev (unsaturated polyester resin tuaj yeem kho tsis pub dhau 1 teev, thaum epoxy resin xav tau ntau tshaj 10 teev).Ob qho khoom siv tsis zoo notus nqi thiab nqi zog ntawm epoxy resin yog siab duaunsaturated polyester cob.UPGM203 (GPO-3) daim ntawv sivunsaturated polyester cob.
