The aim of this study was to determine the
critical ratios of fiber (vfcrit.) In nettle fiber/polymethyl methacrylate
composites depending on fiber thickness. Polymethyl methacrylate, a brittle
matrix, was used for this purpose. Nettle fiber, produced by natural method,
was used in the production of polymethylmethacrylate composites with nettle
fiber fiber with a ratio of 1,25%, 2,5, 3,75 and 5% by Hand
lay-up.The tensile strength, bending strength, and
impact strength of these compenents were used to obtain critical fiber ratios
based on the thickness of the fiber. The physical properties of the fiber and
its interaction with the matrix were determined by XRD and FITIR tests,
respectively. SEM images were examined with the help of the observed
microstructure of the fracture surfaces. According to the obtained data,
critical fiber diameter values in thick fibers are higher than thin fibers. The
results of the study showed that fine fibers had a positive effect on the
mechanical properties of the materials compared to thick fibers.
