Interface modification of clay and graphene platelets reinforced epoxy nanocomposites: a comparative study [PDF]

open access: yes, 2014
The interface between the matrix phase and dispersed phase of a composite plays a critical role in influencing its properties. However, the intricate mecha-nisms of interface are not fully understood, and polymer nanocomposites are no exception.

EPOXY RESINS AND TOUGHENING METHODS OF EPOXY RESINS

open access: yes, 2023
Epoxy resins (EPs) stand at the forefront as the preeminent thermosetting materials, owing to their inherent stability, both mechanically and chemically, coupled with resistance attributes to heat, corrosion, and electrical challenges (Zhao et al., 2022; Sukanto et al., 2021; Kim et al., 2018; Chen et al., 2020).

Curing kinetics and effects of fibre surface treatment and curing parameters on the interfacial and tensile properties of hemp/epoxy composites [PDF]

open access: yes, 2009
The curing kinetics of neat epoxy (NE) and hemp fibre/epoxy composites was studied and assessed using two dynamic models (the Kissinger and Flynn-Wall-Ozawa Models) and an isothermal model (the Autocatalytic Model) which was generally supported by the ...

The effect of epoxy excess on the kinetics of an epoxy–anhydride system

open access: yesJournal of Applied Polymer Science, 2002
AbstractThe uncatalyzed cure of a commercial tetrafunctional epoxy monomer TGDDM (N,N,N′,N′‐tetraglycidyl‐4,4′‐diaminodiphenylmethane) with hexahydrophthalic anhydride (HHPA), using variable stoichiometric ratios is reported. The reaction was followed by differential scanning calorimetry (DSC). Two kinds of experiments were performed: (1) fresh samples
