Abstract
Synthetics fibers have been presenting a high cost of production and are non-biodegradable. For this reason, other alternatives such as natural fibers are being studied for replacing them, in some applications, as reinforcing of composite materials. Natural fibers are biodegradable, abundant, and have low-cost production. Among the natural fibers, the bamboo fiber has been highlighting due to their specific mechanical properties are comparable with specific mechanical properties of glass fiber, are a perennial and abundant resource around the world. This work aims to determine the physical, thermal, and mechanical properties of bamboo fiber (\textit{Guadua Augustifolia}), which was extracted using an unconventional method and were not submitted to surface treatment. The gas pycnometer test was carried out to measure the bamboo fiber density. Then, the thermal degradability was analyzed by thermogravimetry analysis (TGA) to evaluated the thermal stability of bamboo fiber. The manufactures specimens, according to ASTM D3379, were submitted an experimental static test using a universal testing machine was performed to obtaining the tensile strength, elastic modulus, and elongation at break. Finally, it was highlighted the potentialities of the bamboo fiber extracted by veneer rotary-peeling (BFVRP) as reinforcing of composite materials.
