A single specimen of an epoxy/amine thermoset-glass fiber composite was examined, using a freely oscillating torsion pendulum operating at Ç 1 Hz, for different conversions (as measured by T g ) from T g 0 Å 0ЊC to T gϱ Å 184ЊC during cooling and heating temperature scans. T g was increased for succ
The effect of water immersion at 70°C on undercured epoxy thermosets obtained from tris [ 4-(2,3-epoxypropoxy)phenyl] methane and 4,4'-diaminodiphenylsulphone and from N,N-bis (2,3epoxypropyl) aniline and 1,3-diaminobenzene was investigated. It is concluded from water absorption studies, Tg measurem
