The load transfer effectiveness from matrix to reinforcement is depended on the interface condition of the fiber surface and matrix. Chemical treatment can change fiber properties. The current study aims to evaluate the influence of chemical treatment using silane solution on interface shear strength (ISS) of Sansevieria cylindrica fiber (SCF) reinforced epoxy composite. The research procedure includes silane treatment on SCF with percentage silane concentrations of 0.0, 2.5, 5.0, 7.5, and 10.0%. ISS was evaluated by a single fiber pullout procedure. SCF crystallinity, functional group, and morphology were evaluated using X-ray diffraction, Infrared spectrometry, and electron microscope. The result shows that the surface morphology of SCF became rough and the surface rougher after silane treatment of 7.5%. SCF with no treatment has a degree of crystallinity of 66.0%, but after being treated with silane treatment, the degree of crystallinity increased, and the highest value of 75.0% was obtained from the silane treatment of 10.0%. The ISS increases following the increasing silane concentration. The highest ISS of 91.3 MPa was obtained at a silane treatment of 10.0%, with an increasing ISS of 129.0% compared to the control specimen. © 2023 School of Science, IHU. All rights reserved.
