Abstract In this work, new bio-based copoly(ester amide)s were synthesized by a two-step melt polycondensation process, using 2,5-furanedicarboxylic acid dimethyl ester (DMFDC), 1,3-propanediol (PDO), and 1,3-diaminopropane (DAP), with different DAP content. The chemical structure of the obtained poly(trimethylene 2,5-furandicarboxylate)-co-poly(propylene furanamide) (PTF-co-PPAF) copolymers wa...

This research is focused on manufacturing and characterization of hybrid composite laminates obtained different stacking sequences basalt flax fabrics with silane treatments embedded in a partially bio-sourced epoxy resin as matrix. They were manufactured by the vacuum-assisted infusion molding mechanical properties tested tensile, flexural impact conditions. The effect coupling agent fiber/mat...

Abstract A dynamic mechanical thermal analyser (DMTA) was used to develop insight into the properties of bioinspired asymmetric helicoidal carbon fibre reinforced plastic (CFRP) composites as a function architecture using inter-ply stacking angles 0° (UD), 0/90° (cross-ply), 5°, 15°, 10°, 20°, 25° and 30°. Here, we show that CFRP are linearly correlated their oriented ply fractions between 45° ...

Polyethylene’s application for insulating is highly advanced but due to thermoplastic properties, its application confronts constraints such as the limited 70°C temperature of the conductor. Polyethylene thermosetting procedure in which molecules are knotted and a 3D-molecular-network formed is developed to conquer the mentioned problem and to raise the applicable temperature of the i...

In this research, polyvinyl chloride (PVC) with excellent shape-memory effects is 4D printed via fused deposition modeling (FDM) technology. An experimental procedure for successful 3D printing of lab-made filament from PVC granules introduced. Macro- and microstructural features are investigated by means wide-angle X-ray scattering (WAXS), differential scanning calorimetry (DSC), dynamic mecha...

In this study, application relevant toughened epoxy-amine formulations were investigated regarding their mechanical behavior at low temperatures and compared to a non-toughened reference. The application-oriented resins are based on reactive diluent-modified diglycidylether of bisphenol A (DGEBA) which tested 22 °C ?50 in regard fracture toughness (KIC) fatigue crack propagation (da/dN) behavio...

The goal of the work was to prepare thermoplastic starch (TPS), for first time plasticized with ternary deep eutectic solvents (DESs) based on urea/resorcinol/choline chloride (URCC) in a 2:1:1 molar ratio and enriched lignin as an environmentally friendly functional alternative agricultural plastics. Potato effectively modified DES via twin-screw extrusion presence up 10 pph (L10) without sign...

In the present study, we investigated possibility of value-added recycling ultrafine ground tire rubber (uGTR) produced from water jet milling, with an average particle size a few tens microns. Our goal was to compare properties blends different uGTR and conventional fine (fGTR) contents prepared by blending low-density polyethylene (LDPE). We also aimed explore property changes caused larger s...

The aim of this work is synthesis a novel nanocomposite containing Polylactide (PLA) and polyamide 6 (PA6) reinforced with graphene oxide (GO) poly ethylene-butyl acrylate-glycidyl methacrylate) (PTW) compatibilizer during solvent-based method. For purpose, GO was added to the 0.1, 0.3, 0.5, 0.7 1 phr. Morphology, rheology mechanical properties nanocomposites were studied scanning electron micr...
