  • Recently, various kinds of study on light weight structure are performing in the world. The Al honeycomb sandwich structural type adopt for improvement of lightness and structural stability to major part structure of aircraft or spacecraft. Adhesion badness properties of adhesive and adhesion properties of fillet mainly studied about al honeycomb structure. But study for adhesive properties of sandwich construction with surface treatment of Aluminum alloy barely performed. In this study, adhesive film was used between Al and honeycomb core of honeycomb panel[1]. The study for adhesive properties of sandwich construction with surface treatment of AA 5052 skin was performed.

  • Resorcinol-tannin-formaldehyde-latex(RTFL) adhesive was prepared to bond SBR to nylon in reinforced rubber composites. A key factor of adhesive contributes to the adhesion strength between SBR and nylon was the toughness of adhesive itself. Although the stiffness and strength of adhesive film decreased slightly with increasing level of tannin substitution for resorcinol in a standard RFL adhesive, the maximum toughness of adhesive film, which showed yield behavior and high dissipative capacity, was obtain by 60% tannin substitution. However, a marked softening and reduction in toughness occurred at sufficiently high substitution. Also, the adhesive film, which was heat-treated to simulate cure, showed higher strength than the unheated film. Thus, the properties of tannin containing adhesives could be optimized by using 40/60 weight ratio of the resorcinol/tannin in RTFL adhesive composition as well as heat treatment of adhesive film.

  • In the variation of physical properties of adhesive fabrics, the objective of this study is to analyze fitness of fusible interlining to four sorts of fabrics for men's suit with various structural parameters. Four fusible interlinings are used for adhering to fabrics for men's suit. Mechanical properties of these 16 adhesive fabrics fused with these interlinings are measured by KES-FB system for analysing appearance and wearing properties of garments and for examining the fitness of fusible interlining to the fabrics for men's suit. The variation of bending property for adhesive fabrics are found to be higher in the order of interlining 1(Cotton30/Rayon70, plain), interlining 2(Polyester30/Rayon70, warp knit), interlining 4(Polyester, shingosen fabrics with drawing textured yarn) and interlining 3(Polyester, double dot coating interlining). The variation of adhesive effect shows the same results with bending property and shows negative relation with extensibility in weft direction per extensibility in warp direction(EM2/EM1). The variation of peel strength of adhesive fabrics, woolen fabrics in the case of face fabrics and interlining 3 in the case of interlining shows the largest value respectively.

  • This study is to investigate adhesive properties depending on the temperature, humidity, and freeze-thraw of the Steel plate adhesive strengthening method by the epoxy resin. The results are summarized as following. For the temperature variation, the debonding failure appear only after 1 cycle of temperature varoation because the coefficient of thermal expansion of the epoxy resin is comparatively large, and the bonding strength is decreased. The deformation properties and ultrasonic pulse velocity on each materials are similar until 4 cycles on the dry and moisture test. As the freeze-thraw test, the epoxy resin is degraded easily subjected to freeze-thaw cycle, comparatively easy, so the debonding failure may occur in short term because of the freeze-thaw repeatition.p

  • Structural stability and shock absorption are important properties for corrugated board. In order to maintain structural stability, adhesive properties between top/bottom liners and corrugated medium are not only essential but also important for productivity and product quality. Borax has been an essential ingredient in corrugating adhesive solution. Borax increases viscosity, bonding between starchs and green adhesive bond. The objective of this research is to improving adhesive strength and viscosity stability by adding cross-linking agent instead of borax. Rheology and penetration of main starch gelatinization slurry were affected by borax addition level. Borax increased viscosity and decreased viscosity stability, while cross-linking additives increased viscosity stability and adhesive strength by anchoring effect.

  • Over the last decade, Sick Building Syndrome has become a significant social issue in Korea and many methods have been considered to maintain comfortable indoor air quality. To reduce toxic substances emitted from wood composite products, the source control is an efficient method through the reduction of formaldehyde content by using natural material-based adhesives for composite wood products production. Among alternative materials, soybean protein is considered an appropriate natural material to replace formaldehyde-based resin and many efforts have been made to produce new products, such as soap, shampoo, ink, resin, adhesive and textile through changing the chemical or physical properties of soybean. To process soybeans into these useful products, the beans are dehulled and the oil is removed by crushing at very high pressure or by solvent extraction. For use soybean as an adhesive, it is processed at temperatures below $70^{\circ}C$ to preserve the alkaline solubility of the proteins. In addition, soybean-based adhesive is undergone treatment process to improve mechanical properties using urea, urease inhibitor N-(n-butyl) thiophosphoric triamide and sodium dodecyl sulfate. The modified soybean-based adhesive exhibited sufficient mechanical properties to use as an adhesive for composite wood products. This paper is a review article to discuss the possibilities of soybean-based adhesive for environment-friendly furniture materials.

  • To find a new use of wood tar which is obtained from the manufacturing process of wood charcoal, a resol type of phenol adhesive using wood tar was made and some adhesion tests on plywood were examined. Phenol adhesive synthesized with pine tar was almost same as an original phenol adhesive in physical properties such as solid content and viscosity and tensile-shear adhesive strength of plywood made of phenol adhesive synthesized with pine tar was not much lower than the original one in non-waterproof and waterproof tests. Phenol adhesive synthesized with oak tar, however, was different from original phenol adhesive in physical properties. Adhesive strength of plywood made of oak tar was $50\%$ lower than the original one on waterproof tests. The amount of emitted formaldehyde increased as the amount of wood tar increased.

  • In making emulsion type pressure sensitive adhesive (PSA), environmentally friendly Tween series nonionic surfactants were used to find out the possibility of substituting the traditional nonyl-phenyl nonionic surfactant (NP-40) by comparing their adhesive properties. Results exhibited that the PSA used Tween series nonionic surfactants showed much better adhesive properties in peel strength and holding power than that used NP-40.
