Shape memory polymers (SMP) have piqued the interest of research and development sector due to their new features immense potential. The polymer matrix epoxy was changed using varied weight percentages aliphatic monomer-neopentyl glycol diglycidyl ether (NGDE), optimal percentage NGDE identified. NGDE-CNT are 0, 0.3, 0.6, 0.9, 1.2, 1.5. use nanofillers such as carbon nanotubes (CNT) has been pr...

In the present work, a specific three-point bending test is applied to evaluate how roughness can impact bond strength (adherence) and mechanism of interfacial failure initiation. The study conducted using an aluminum alloy 2024-T3 as substrate DGEBA (polyepoxide bisphenol A diglycidyl ether) /DETA (diethylenetriamine) adhesive, considering different abrasive surface treatments. An optimal reac...

In this experimental investigation, the influence of graphene nanoplatelets (GNPs) on dynamic behavior polymeric material such as diglycidyl ether bisphenol A (DGEBA) epoxy is investigated using Split Hopkinson Pressure Bar (SHPB). Nanocomposite samples with a different weight percentage GNPs i.e. 0, 1, 2, 5 wt% were fabricated and tested under compression to understand nanofillers mechanical p...

AIMS To evaluate effects of exposure to bisphenol A diglycidyl ether (BADGE) on urinary excretion of bisphenol A, and plasma gonadotrophic hormones and testosterone in male epoxy resin sprayers. METHODS Cross sectional study of 42 workers whose job was to spray epoxy resin hardening agents including BADGE and mixed organic solvents, and 42 matched control workers without BADGE use in the same...

A strategy for toughening epoxy thermosets via topological rearrangement of cross-linked networks is presented. Amine-cured systems were modified by mixing partially reacted substructures (mPRS), which synthesized curing tetraglycidyl ether diaminodiphenylmethane (TGDDM) and polyether monoamine (Jeffamine M1000) to provide free unbound surfaces that enhance protovoid formation during deformatio...
