We use molecular dynamics simulations to study the thermo-mechanical response of a thermosetting polymer (diglycidyl ether of bisphenol A with 3,30diamino-Diphenylsulfone) subject to cyclic loading for a family of tri-axial deformation paths and two different load levels and strain rates. We focus on how the relative amount of deviatoric and volumetric deformation affects strain accumulation an...

The toughening of an aromatic amine-cured diglycidyl ether of bisphenoI-A epoxy with particles of crystalline polymers was studied. The crystalline polymers were poly(butylene terephthalate), nylon 6, and poly(vinylidene fluoride). Nylon 6 and poly(vinylidene fluoride) were found to toughen the epoxy about as well as did an equivalent amount of CTBN rubber. Poly(butylene terephthalate) was foun...

In this paper, we report on the development of a new and broadly applicable strategy to produce thermally mendable polymeric materials, demonstrated with an epoxy/poly(-caprolactone) (PCL) phase-separated blend. The initially miscible blend composed of 15.5 wt % PCL undergoes polymerization-induced phase separation during cross-linking of the epoxy, yielding a "bricks and mortar" morphology whe...

The synthesis of polymers from renewable resources is a burning issue that is actively investigated. Polyepoxide networks constitute a major class of thermosetting polymers and are extensively used as coatings, electronic materials, adhesives. Owing to their outstanding mechanical and electrical properties, chemical resistance, adhesion, and minimal shrinkage after curing, they are used in stru...

Surface metallization is amongst the recent trends in polymer and matrix composites (PMCs) research industries to improve electrical thermal properties exploit subsequent utilization aerospace sector. Specifically, have been subjected limitations form of high temperature exposure substrate deterioration. The present study encompasses a new strategy manufacturing process. first stage hybrid ther...

High-performance fiber-reinforced thermoset composites processed by additive manufacturing (3D printing) are attracting substantial attention in both academic and industrial fields a market currently dominated thermoplastic matrices. Thermoset polymers have, nevertheless, several advantages over ones. This study aims at recommending suitable fibers processing conditions that effectively improve...

Abstract Fusion assembly is a highly promising technique for joining thermoplastic composite to thermoset composites, enabling the use of both most affordable material and process each substructure. However, some major challenges need be addressed such as functionalizing surface through co-curing with an appropriate interlayer or realizing fast robust welding that meets all quality mechanical r...
