The relaxation modulus of the material can be taken as a linear function of crosslinkingdensity.
材料的松驰模量可以表示为交联度的线性函数。

The results shows that epoxy resins containing rigid rod structure or many epoxy groups have a high glass transition temperature (Tg) because of high cross-linkingdensity.
In the material with relatively low cross-linkingdensity, extensive fracture process stripe is formed which is induced by the combined stress field near the rubber particles.
