Mechanical Properties of Bifunctional/Tetrafunctional Epoxy Blends

초록

Diglycidyl ether of bisphenol A(DGEBA)와 4,4'-tetraglycidyl diaminodiphenyl methane(TGDDM)으로 구성된 에폭시 블렌드를 여섯가지 각기 다른 조성을 갖도록 배합하여 각기 다른 다섯가지 경화조건을 이용하여 경화시켰다. 에폭시 블렌드의 경화를 위하여 당랑비 만큼의 diaminodiphenyl methane(DDM)을 경화제로 첨가하였다. 에폭시 블렌드의 조성변화에 따른 유리 전이온도의 변화를 differential scanning calorimeter(DSC)를 이용하여 측정하였다. 에폭시 블렌드의 조성에 따른 밀도의 변화가 고찰되었다. 경화된 에폭시 블렌드의 인장강도 및 충격강도에 미치는 블렌드의 조성 및 경화조건 변화의 영향이 고찰되었다. 충격강도 시험에 의해서 생긴 에폭시 블렌드의 파단면을 관찰하기 위하여 광학 현미경을 이용하였다.

Epoxy/epoxy blends composed of diglycidyl ether of bisphenol A(DBGBA) and 4.4'-tetraglycidyl diaminodiphenyl methane(TGDDM) were formulated with six different blend compositions and cured under five different cure conditions. Stoichiometric amount of diaminodipheny1 methane(DDM) was used to cure the epoxy blends. Glass transition temperatures of the epoxy blends were measured using a DSC(differential scanning calorimeter). Density Change with blend compositions was investigated. Effects of blend compositions and conditions on the tensile and impact strength of the cured epoxy/epoxy blend were investigated.
