Comportamento Mecânico Do Epóxi de Fibra de Bambu Usando XRD
A bamboo fiber reinforced epoxy composite is a promising material due to its high strength and low weight. In this article, we will explore the mechanical behavior of this composite using X-ray diffraction (XRD) analysis.
The XRD analysis was performed to determine the crystal structure and phase composition of the bamboo fiber reinforced epoxy composite. The sample was prepared by cutting the composite into small pieces and mounting it on a sample holder. The XRD patterns were then obtained by scanning the sample from 10° to 80° with a step size of 0.02°.
The mechanical properties of the composite, including tensile strength, flexural strength, and impact strength, were evaluated using standard testing methods. The samples were prepared according to the ASTM standards and tested using a universal testing machine.
XRD Analysis Results
The XRD analysis revealed the presence of bamboo fibers and epoxy resin in the composite. The diffraction peaks corresponding to the bamboo fibers indicated a crystalline structure, while the diffraction peaks corresponding to the epoxy resin indicated an amorphous structure.
Mechanical Testing Results
The tensile strength of the bamboo fiber reinforced epoxy composite was found to be [value] MPa, which is higher than that of pure epoxy. The flexural strength and impact strength were also significantly improved with the addition of bamboo fibers.
