Promising Area

Joining thin sheets of aluminium and its alloys is a promising area in the field of joining materials. Nowadays, joining methods that do not melt the material itself are increasingly being utilised. This paper deals with adhesive bonding of aluminium alloy A5754 by two-component epoxy resins. Theresults show that joints bonded by Hysol 9466 have appropriate mechanical properties, but that joints bonded by Hysol 9492 have better thermal stability.

Abstract Joining materials by adhesive bonding is used across all industrial branches. The occurrence of adhesive bonds in machine constructions is still more frequent because of the development of adhesives which are able to meet various requirements of designers. This trend is observable also in agriculture - in the construction of agricultural machines. There even exists a cooperation between the companies developing the adhesives and the agricultural machines producers. The production process of machines and equipment must consider a required production tact. Adhesives and the process of their hardening have to meet these requirements. In the sphere of agriculture, epoxy resins hardening based either on hardeners or heating are used. Mechanical properties of two-component epoxy resins depending on variable amount of the hardener starting crosslinking of these reactoplastics are described.

In this article,polyethersulfone and flourene-coating epoxy resin were utilized tomodify both the toughness and the mechanical properties of traditional epoxy resins. The cure kineticsand the thermal stabilityof the resultedblends were tested by differential scanning calorimetry technology and thermogravimetric analysis, respectively. Additionally, the mechanical properties of resulted thermosets were discussed after tested by Dynamic Thermomechanical Analyzer.When compared to the traditional epoxides, the obtained blends exhibit much better heat resistance, thermal stability and mechanical properties.

Nanocomposites of ethylene vinyl acetate (EVA) copolymer, polystyrene (PS) nanoparticles, and montmorillonite (MMT) were prepared by latex compounding. The nanolatex of PS was synthesized by differential microemulsion polymerization and then blended with EVA at EVA/PS dry weight ratios of 90/10, 80/20, and 70/30, before mixing with MMT at 1, 3, or 5 parts per hundred rubbers. The latex composite mixtures were cast on a glass mold and compressed into thin sheets. The nanocomposites were characterized for their structures, mechanical properties, and thermal behaviors. The tensile strength, Young’s modulus, storage modulus, and thermal stability were all improved with the incorporation of MMT, although the extent of such depended upon and varied with the EVA/PS ratio of the nanocomposite.

A new two-component polyurethane adhesive was prepared with castor oil used as main agent and castor oil modified TDI used as curing agent.The effect of castor oil on the mechanical properties, adhesion properties and thermal stability of this adhesive were studied.This paper show us that TDI could be used as curing agent after modification. When the NCO/OH in curing agent and main agent:curing agent were 1.6 and 3:5 respectively, high performance adhesive was obtained.

Epoxy resins have been presenting a lot of scientific and technical interests and organic modified epoxy resins have recently receiving a great deal of attention. For obtaining the composite materials with good mechanical proprieties, a large variety of organic modification agents were used. For this study gluten and gelatin had been used as modifying agents thinking that their dispersion inside the polymer could increase the polymer biocompatibility. Equal amounts of the proteins were milled together and the obtained compound was used to form 1 to 5% weight ratios organic agents modified epoxy materials. To highlight the effect of these proteins in epoxy matrix mechanical tests as three-point bending and compression were performed.
