the effects of hydroxy-terminated butadiene-acrylonitrile copolymer(HTBN) on the toughness of epoxy resin were investigated. Only by adding 10 to 20 phr of HTBN
the properties of epoxy resin would be modified greatly
e.g.
lap shear strength
impact strength
tensile strength
elongation and glass transition temperature are 30 MPa
9 ×10-2 J/ cm2
61 MPa
10% and 115℃
respectively
compared with 24 MPa
3.4×10-1 J/cm2
30 MPa
5% and 124℃
respectively for a resin without HTBN. Two-phase structure of tonghened epoxy resin was observed by studies of DSC and scanning electron microscopy.
