Epoxy resins constitute a very significant portion of all high-performance plastics due to their excellent thermal and mechanical properties that appear in wide range applications. Nevertheless, traditional epoxy networks show limitations regarding chemical recycling covalently crosslinked structures. The current methods recycle are not indeed through sustainable ways, but this issue could be s...

Epoxy resins are thermosetting polymers with an extensive set of applications such as anticorrosive coatings, adhesives, matrices for fibre reinforced composites and elements electronic systems automotive, aerospace construction industries. ?he use epoxy in many high-performance is often restricted by their brittle flammable nature, the relatively low fracture toughness poor thermal electrical ...

Molecular dynamics and molecular mechanics simulations have been used to study thermo-mechanical response of highly cross-linked polymers composed of epoxy resin DGEBA and hardener DETDA. The effective cross-linking approach used in this work allowed construction of a set of stress-free molecular models with high conversion degree containing up to 35000 atoms. The generated structures were used...

This paper investigated the effect of the amine-functionalized carbon nanotubes (CNTs) on the thermomechanical properties of CNT/epoxy nanocomposites. Mechanical stirring and ultra-sonication were utilized to uniformly disperse CNTs into the epoxy matrix. Non-functionalized and amine-functionalized CNTs with different weight percentages (wt. %) were mixed into the epoxy resin. Using standard te...

epoxy – polysulfide copolymers without or with low amounts of epoxy in their structure have poor mechanical properties in oxidative curing system.to strengthen the mechanical properties of polysulfide elastomer inclusion of epoxy resin (epon828) as hard segment was studied. ft-ir spectroscopy and rheometry were used to verify the formation of epoxy-polysulfide copolymer.  results obtained from ...

Over a billion microwave ovens are used every day thus witnessing the importance of microwave heating in the world today. Microwave processing of polymers is a comparatively recent and vastly expanding field in industry due to economical advantages through energy saving and accelerated manufacture. Factors that hinder the use of microwaves in materials processing are decreasing every day. Epoxy...

Preforming processes can be used for automated manufacturing of fiber reinforced polymers. Different technologies are processing dry textile fabrics into 2D or 3D preforms. Due to missing tack fabrics, auxiliary binder systems fixation the onto a substrate material and in order achieve sufficient adhesion between layers. In this study, seven reactive non-reactive tackifying agents have been dis...

The design and necessity of corrosion-resisting nanocarbon nanocomposites have been investigated for cutting-edge aerospace applications. In this regard, nanofillers, especially carbon nanotubes, graphene, nanodiamond, etc. used to fill in various polymeric matrices (thermosets, thermoplastics, conducting polymers) develop anti-rusting space-related nanocomposites. This review fundamentally emp...
