Mechanical and Thermal Properties of Chemically Modified Epoxy Resin
Diglycidyl ether of bisphenol-A (DGEBA), having number average molecular weight (Mn) 375, was modified by incorporating the hydroxyl terminated polybutadiene (HTPB) based prepolymer using isophorone diisocyanate as a coupling agent. To increase the compatibility between the epoxy resin and HTPB part, polar groups were introduced in the later to achieve physical and chemical interactions between...
متن کاملKinetics and Mechanism of Curing Epoxy/anhydride Systems
The paper reports the results of studying the kinetics of DGEBA reactions with maleic anhydride catalyzed by N, N-dimethyl aniline (DMA). This stuffs are used as photoelastic model materials. The origination of monoester was studied separately on a model reaction of maleic anhydride with isopropyl alcohol. The subsequent reaction of epoxy groups with monoester was examined on a system of epoxy ...
متن کاملSynthesis and characterization of oxazolidones with improved thermal stability
To increase thermal stability for high performance applications of epoxy resin system – Diglycidal Ether of bisphenol-A (DGEBA), the epoxy backbone is modified to incorporate aromatic and heterocyclic rings i.e. the oxazolidone ring. FTIR studies were conducted during the synthesis at various intervals. Appearance of peak at 1754 cm confirms the presence of oxazolidone ring and absence of peak ...
متن کاملThermal Stability of Imidazolium Modified Clay and Tgddm-based Epoxy Nanocomposites
High performance epoxy resin (tetra-glycidyl-4,4’diamino-diphenyl methane-TGDDM) is brittle and is sensitive to moisture absorption and thermooxidative effects. An approach to mitigate polymer sensitivity towards moisture and thermal effects is to add clay. The addition of clay to resin systems (e.g. diglycidyl ether bisphenol A-DGEBA) has often yielded an overall improvement in properties of t...
متن کاملThermal Conductivity of Polyimide/carbon Nanofiller Blends
INTRODUCTION Combining polymers with an organic or inorganic filler to produce a polymer composite is common in the production and processing of modern plastics. Recently, filler sizes have been reduced to nanometer dimensions resulting in a new class of materials termed polymer nanocomposites (PNC). PNCs are commonly defined as the combination of a polymer matrix resin with inclusions that hav...
