| dc.description.abstract | Basalt fiber has been proposed as an environmentally friendly alternative to traditional petroleum-derived fibers such as E-glass and carbon. Composite tubular structures are commonly used E-glass or carbon as a reinforcement materials have led to several effects, such as the substance being non-recyclable and nonbiodegradable. The durability of composite tubular structure is relying on damage resistance and damage tolerance. The primary aim of this research is to investigate the characteristics of Basalt reinforced epoxy composite tubes based on mechanical, impact and post-impact performances. Four different tube winding angles, [±45°]3, [±55°]3, [±65°]3 and [±75°]3 with an average of 3 mm thickness and 50 mm of inner diameter were selected. Hoop tensile and longitudinal tensile tests were conducted on carbon and three hybrid tubes for comparison purposes. Drop-weight impact tests were performed at different energy levels, which are 4, 6, 8 and 10 Joules using hemispherical tip impactor with different diameters of 6.3, 10, 12.7 and 15.9 mm. Compression after impact tests were carried out to determine the damage tolerance based on different parameters, including impact energy, shape of impactor tip, tubes’ reinforcement materials, tubes’ winding angles and compression loading rates. The results show that Basalt tubes produced up to 19.7% and 13.8% higher hoop and longitudinal strength respectively, have 3.8% higher damage resistance and up to 44% higher damage tolerance when compared to E-glass tubes. Scanning Electron Microscope was used to analyze the surface and texture morphology for both normal and damaged modes. There was evidence that matrix cracking and fiber fractures obtained from impact loads has affected up to 47% compressive strength of Basalt composite tubes. In overall, Basalt filament wound tubes show promising characteristics under mechanical, impact and post-impact loads | |
