Abstract:
In this paper, the influence of pre-tension on elongation percentage at specified load for knits was studied .First of all, initial elongation and elongation percentage at specified load for different retractility knits were tested and analyzed at different pre-tension. And then significance of influence of pre-tension on initial elongation and elongation percentage at specified load for knits were analyzed by means of variance analysis. Results show that the pre-tension has significant influence on initial elongation for different retractility knits, and it has no significant influence on elongation percentage at specified load for little retractility knits, and it has significant influence on elongation percentage at specified load for well retractility knits. The greater the pre-tension is, the more significant the influence is, Therefore it is suggested that pre-tension is generally less than 0.1N in the test.The research results can provide a certain reference to stretch and recovery test for knits and test standard recension .

Abstract:
Abstract This experimental study reveals the effects of CaF2, FeMn and NiO additions to the base fluxes on tensile strength and percentage elongation of the weld metal. The aim of this study is to develop suitable flux for mild steel for high tensile strength, impact strength and ductility. Bead on plate welds were made using submerged arc welding process. Mathematical model for percentage elongation and UTS of mild steel welds were made. The elements transfer to the welds have been correlated with the above mechanical performance characteristics. The effect of oxygen content on weld elongation and UTS also has been deduced. This study shows that CaF2 and NiO are the significant factors for tensile strength while FeMn is not significant for tensile strength. However, for elongation besides CaF2, the interaction of CaF2 and FeMn was also found significant. The effects of basicity index of the flux and carbon equivalent of the welds on tensile strength and percentage elongation of the welds have also been evaluated.

Abstract:
The effect of maleated polypropylene (MAPP) as binder on the mechanical properties of kenaf fibre/polypropylene (KF/PP) composites is studied. Ratios between kenaf fibre and PP having 10:90, 30:70 and 50:50 in weight ratio were selected. Further, MAPP having 1, 3 and 5 percent in percentage of weight ratio was mixed in KF/PP composites. Hot press machine was used to produce tensile test samples of KF/PP composites. The mechanical properties that are tensile strength, tensile modulus and elongation at break of KF-PP composites were obtained from tensile test result. It is found that the tensile strength and tensile modulus increase with increasing the kenaf fibre loading and higher percentage of MAPP. Further, the elongation at break for KF/PP composites shows lower result when increasing of kenaf fibre loading. However, when percentage of MAPP added in KF/PP composites increases, the elongation at break increased slightly. Thus, result shows that kenaf fibre/PP composites with binder were better in tensile strength, tensile modulus however the elongation at break shows weak result unless the binder was added.

Abstract:
To compare maximum load, percentage of elongation, physical characteristics of 4 types of dental floss: (1) Thai Silk Floss (silk, waxed), (2) Oral B® Essential Floss (nylon, waxed), (3) Experimental Floss Xu (nylon, unwaxed), (4) Experimental Floss Xw (nylon, waxed). Four types of floss were tested (n=30) with a Universal Testing Machine (Instron®). Each sample (30 cm long, 5 cm segment) was fixed, and pulled apart with load cell of 100 N and a test speed of 100 mm/min. Physical characteristics were investigated by digital microscope under 2.5×10 magnification, and scanning electron microscope under 1×100 and 5×100 magnification. The size of the filaments was measured in micron (μm) and the fineness was measured in Denier. For mechanical properties, the maximum load and the percentage of elongation were presented as mean ± SD. The distribution of the data was calculated by the Kolmogorov-Smirnov test. One-way ANOVA and multiple comparison (Tukey HSD) were used to analyze the differences among the groups with the level of a statistical difference at p < 0.05. The maximum load of Floss Xu, Floss Xw, Oral B and Thai Silk were 47.39, 46.46, 25.38, and 23.70 N, respectively. The percentage of elongation of Oral B, Floss Xw, Floss Xu and Thai Silk were 72.43, 44.62, 31.25, and 16.44%, respectively. All 4 types of dental floss showed statistically differences in both the maximum load and percentage of elongation at p < 0.05, except for maximum load between Floss Xw and Floss Xu that showed no statistically significant difference. Physical characteristics of Thai silk revealed the most disintegrated, the smallest, and the least fine filaments. Floss Xu had the highest maximum load. Oral B had the highest percentage of elongation. Wax coating on Floss X increased the elongation but had no significant effect on the maximum load. The physical characteristics of Thai Silk resulted in the lowest mechanical properties values.

Abstract:
AbstrakPada proses produksi, pengaturan parameter poses memegang peranan penting terhadap tercapainya mutu produk yang dihasilkan. Pada proses pengelasan, salah satu parameter proses pengelasan yang harus diperhatikan adalah besar arus pengelasan. Kajian ini dilakukan untuk mengetahui besar kuat arus yang sesuai pada proses pengelasan material ST 37 menggunakan proses pengelasan MIG (Metal Inert Gas). Pengujian dilakukan dengan memvariasikan besar kuat arus pengelasan yaitu pada 90A, 100A, 110A serta 120A. Pengujian tarik dilakukan terhadap hasil pengelasan tersebut. Hasil pengujian tarik menunjukkan, pengelasan menggunakan kuat arus sebesar 110A memberikan nilai yang maksimum pada beberapa besaran pengujian. Untuk nilai tegangan tarik, σ memiliki nilai 16.9 kg/mm2, modulus elastisitas, E, 3.14 kg/mm2 serta Regangan ε, 5.42%. Kata kunci: pengelasan, Metal Inert Gas, Tegangan Tarik, modulus elastisitas AbstractThe appropriate production parameter process plays an important role in fulfill the quality of the products such as mechanical properties like tensile strength and percentage of elongation of MIG welded joints. Likewise, in the welding process, one of the welding process parameters that is welding current must be considered, since the welding current is most influential parameters affecting weld penetration, deposition rate, weld bead geometry and quality of weld metal. Variation of welding current on MIG (Metal Inert Gas) welding process on ST 37 specimen was to examine the effects on like tensile strength and percentage of elongation and elasticity modulus. From the experiment, it is found that when welding current increased up to 110 Ampere the tensile strength tends to incline then slightly decline when welding current increased, modulus elasticity value and percentage of elongation value as well. The maximum value of tensile strength 16.9 kg/mm2 percentage of elongation value 5.42%. and modulus of elasticity 3.14 kg/mm2 were gained at 110 ampere welding current Keywords: welding process, Metal Inert Gas, Tensile strength, elasticity modulus ,percentage of elongation

Abstract:
Non-treated and silane-treated kenaf bast/natural rubber latex foam (NRLF) were prepared using the Dunlop method at different filler loading (0, 3, 5, and 7 pphr). The properties were investigated in terms of mechanical properties, tensile, compression, hardness, and swelling behavior. Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) were used to characterize kenaf bast/NRLF. With the modulus at 100% elongation (M100), the compression strength and hardness showed increments in value with increments of kenaf loading. However, different results showed in tensile strength, elongation at break, swelling percentage, and recovery percentage, which decreased at higher filler loading. Silane-treated kenaf bast/NRLF showed higher value in all properties except for elongation at break, swelling, and recovery percentage. The improvement of properties was supported by SEM surface morphological studies that showed better adhesion between the rubber matrix and kenaf filler.

Abstract:
Coir fiber (CF) reinforced polypropylene (PP) composites were fabricated using an extruder machine. The fiber contents were varied 5 to 20% and physico-mechanical properties as well as bio-degradability were also tested. Ultimate tensile strength and flexural strength decreases with the increases of percentages of fiber addition. Lowest percentage elongation is observed at 20% CF+PP composite which are rigid in nature. Leeb rebound hardness also decreases with the increase of percentage of raw fiber addition. The bio-degradation of different percentage of CF and PP composites in soil and saline water increased with increase of coir fiber content. Thus, it showed that higher percentage of coir fiber was produced more biodegradable and eco-friendly byproducts. However, higher percentages of coir fiber decrease the mechanical properties. A moderate percentage of coir fiber i.e. 15% CF +PP showed the good mechanical properties as well as considerable amount of bio-degradability in soil and saline water.J. Environ.

Abstract:
The present study focuses on improving the ultimate tensile strength of friction stir welded carbon steel (AISI 1018). The effect of the process parameters (welding speed, tool RPM, and shoulder diameter) on the response parameters (ultimate tensile strength, percentage elongation and percentage reduction in area) were studied. Response surface methodology was used to develop the mathematical model for response parameters, and the adequacy of the model was checked using analysis of variance (ANOVA). The welding speed and tool RPM were found to affect the ultimate tensile strength significantly. The percentage elongation was affected only by welding speed. The percentage reduction in the area was affected by welding speed and shoulder diameter. The microstructure and microhardness of the weld have been studied and reported in the study.
