| Abstract: | Mechanical properties of an epoxy resin system (neat resin castings) based on
diglycidyl ether of bisphenol-A (DGEBA) cured with different amounts of
phosphorous based amine, tris(3-aminophenyl) phosphine oxide (TAP) are
reported. Influence of stoichiometric imbalance on the thermoelastic properties
of the epoxy-amine system is also discussed. Testing of dynamic mechanical
properties has been done using Rheovibron DDV-III-EA from ambient temperature
to 250 °C. The results show that variation in stoichiometry can affect material
properties such as modulus (Em) and glass transition temperature
(Tg). Various parameters, viz.
molecular weight between crosslinks (Mc), apparent
front factor ( a), and crosslink density (ρc) have been
calculated for all the compositions. Also, the effect of thermal and boiling
water ageing on material properties for 100 h are reported. |
