In this contribution, we reported the investigation of the formation and confined crystallization behavior of polyethylene nanophases in epoxy thermosets. The nanostructured epoxy thermosets were prepared by the use of a poly(e-caprolactone)-block-polyethylene-block-poly(e-caprolactone) (PCL-b-PE-b-PCL) triblock copolymer. The crystalline midblock (viz. PE) of the triblock copolymer was prepared from an α,ω-diacetoxy-terminated polycyclooctadiene with the molecular weight as high as Mn = 11,000,...

The indentation test is a popular experimental method to measure a material’s mechanical properties such as elastic modulus and hardness, and the Oliver–Pharr method is commonly used in commercial indentation instruments to obtain these two quantities. To apply the Oliver–Pharr method correctly in all of these cases, it is essential to know the limitations of this method. The present study focuses on the applicability of the Oliver–Pharr method to measure the mechanical properties of particles i...

Dynamic vulcanization was successfully applied to epoxy resin reinforced polypropylene (PP)/ethylene-octene copolymer (POE) blends, and the effects of different compatibilizers on the morphology and properties of dynamically cured PP/POE/epoxy blends were studied. The results show that dynamically cured PP/POE/epoxy blends compatibilized with maleic anhydride-grafted polypropylene (MAH-g-PP) have a three-phase structure consisting of POE and epoxy particles dispersed in the PP continuous phase, ...

A new method concerning the simultaneous reinforcing and toughening of polypropylene (PP) is reported. Dynamic cure of the epoxy resin with 2-ethylene-4-methane-imidazole was successfully applied in the PP/maleic anhydride grafted styrene–ethylene–butylene–styrene (MAH-g-SEBS) triblock co-polymer, and the obtained blends were named as dynamically cured PP/MAH-g-SEBS/epoxy blends. The stiffness and toughness of the blends are in a good balance, and the smaller size of the epoxy particle in the PP...

Neste trabalho foi estudada a reacao entre polietileno glicol (PEG) e uma resina epoxidica a base de diglicidil eter de bisfenol A (DGEBA), na presenca de N,N-dimetilbenzilamina (DMBA), sendo os produtos desta reacao avaliados por espectroscopia no infravermelho (FTIR), espectroscopia de ressonância magnetica nuclear de proton (RMN-1H) e medidas de viscosidade cone-prato. Amostras curadas com um endurecedor a base de poliamina foram tambem submetidas a ensaios de tracao e calorimetria explorator...

Hydrophilic and anti-fouling HDPE/PE-b-PEG microporous membranes were prepared by blending high density polyethylene (HDPE) and amphiphilic copolymer polyethylene-block-poly(ethylene glycol) (PE-b-PEG) through the liquid–liquid thermally induced phase separation (L–L TIPS) process. Compared with pure HDPE membrane, HDPE/PE-b-PEG blend membranes exhibit larger water permeation flux due to the segregation of the hydrophilic PEG segments at the membrane surface, which was confirmed by X-ray photoel...

Reactive mixing of epoxy resin with polypropylene (PP) and talc were carried out on a co-rotating twin screw extruder. The prepared samples were injection molded to produce the specimens for the measurements of the shrinkage rate. The microstructure of the composites was studied by scanning electron microscope and correlated to the orientation of filler particles and shrinkage behavior. The nano size epoxy resin particles are obvious in SEM images both in the PP matrix and also adhered on the ta...

A method concerning with the simultaneous reinforcing and toughening of polypropylene (PP) was reported. Dynamical cure of the epoxy resin with 2-ethylene-4-methane-imidazole (EMI-2,4) was successfully applied in the PP/maleic anhydride-grafted ethylene-vinyl acetate copolymer (MAH-g-EVA), and the obtained blends named as dynamically cured PP/MAH-g-EVA/epoxy blends. The stiffness and toughness of the blends are in a good balance, and the smaller size of epoxy particle in the PP/MAH-g-EVA/epoxy b...

Abstract One of the main limitations in application of polymers, particularly thermoplastic polymers such as high density polyethylene (HDPE) and polypropylene (PP), is their poor thermal properties. To promote mechanical and thermal properties of HDPE, ceramic phases are added to it. In the current research, to enhance thermal properties of HDPE, nano-sized calcium carbonate was used. For this purpose, HDPE/10%CaCO 3 nanocomposite was fabricated using a twin screw mixer–single screw extruder. T...

Block copolymer modified epoxy resins have generated significant interest since it was demonstrated that the combination could lead to nanostructured thermosets through self-assembly. Over moderate to high polymer concentration the system behaves as expected for a block copolymer in a solvent selective for one block. Two types of copolymers have been studied: non-reactive and reactive modifiers. Morphologies such as copolymer vesicle and spherical/wormlike micelles can be formed under the approp...

Abstract This paper presents the development of an ABAQUS™ plug-in for estimation of the effective properties of heterogeneous three-dimensional periodic media using the asymptotic homogenization method (AHM). The developed plug-in is user-friendly and requires only basic skills in ABAQUS™. All aspects of the plug-in development are presented, including the solutions found to implement this approach within the finite element package in ABAQUS™. The application of the load cases is performed by u...
