Effect of fiber amount on mechanical and thermal properties of (3-aminopropyl) triethoxysilane treated basalt fiber reinforced ABS composites

This paper investigates the effect of fiber concentration on the mechanical and thermal characteristics of the (3-Aminopropyl) triethoxysilane treated basalt fiber (BF) reinforced acrylonitrile-butadiene-styrene (ABS) composites. The composites are produced with extrusion process and get final shape with injection moulding process. The ratio of the BF used in the composites is 5, 10, 20 and 30 wt\%. The characterization of the composites is performed via tensile, flexural, impact tests, dynamic mechanical analysis (DMA) and thermal gravimetric analysis (TGA). Correlation analyses are also performed to determine the relationships between the tensile, flexural and impact properties. When the test results are considered, a remarkable improvement in the tensile strength is achieved in high BF (20 and 30 wt\%) containing composites. As the concentration of BF increases, the flexural strength improves steadily. The elastic modulus shows a rising trend as the BF ratio increases. The addition of BF causes increase at 4 degrees C in glass transition temperature (T-g). From TGA analysis, the main decomposition step of ABS is not change and the residue yield increases as the added amount of BF increases. An excellent directly linear correlation is determined between the tensile and flexural strength, while the impact strength shows a good inversely linear correlation with the tensile and flexural strength

The mechanical and thermal properties of chopped basalt fiber-reinforced poly (butylene terephthalate) composites: Effect of fiber amount and length

In this study, the effects of basalt fiber (BF) amount and initial fiber length on tensile, flexural and impact properties of poly (butylene terephthalate) (PBT)-based composites are studied. The effect of BF amount on thermomechanical and thermal properties of the composites is also investigated using dynamic mechanical analysis, differential scanning calorimeter and thermal gravimetric analysis. The BF is used at concentrations of 5, 10, 20 and 30 wt% and with different initial lengths of 3, 6 and 12 mm under constant loading of BF (20 wt%). According to the test results, the addition of BF improves the tensile strength and thermal stability of PBT at 20 and 30 wt% loading. Flexural strength and elastic modulus increase steadily as the added amount of BF increases. The addition of BF favors crystallization up to 10 wt% loading. No remarkable effect of initial fiber length is observed on the mechanical properties of the composites

The effect of a phosphorus-based FR on the fire performance and flammability properties of basalt fiber-reinforced acrylonitrile-butadiene-styrene composites

This study focuses on the improvement in fire performance, and flame retardancy (FR) properties of chopped basalt fiber -reinforced acrylonitrile-butadiene-styrene (ABS) composites. For this purpose, different amounts of aluminum diethyl phosphinate (AlPi) compound (5, 10, and 15 wt%) were incorporated in the composites. The FR properties of the composites were examined via limiting oxygen index (LOI), UL-94 standard, and mass loss calorimeter tests. Thermogravimetric analysis was carried out to analyze the decomposition behavior of the composites. SEM inspection was also performed to examine the char surfaces of the composites. The results and findings showed that the introduction of AlPi compound into the composite structure leads to promotion in the char yield and improves the fire performance of the ABS matrix. As the added amount of AlPi into the composite increased, the LOI value of the composite increased. The addition of 15 wt% AlPi resulted in a UL-94 rating of V1 and the LOI value of 31.4%
