Abstrak Pengujian ini bertujuan untuk mengetahui pengaruh prosentase fraksi volume serat lidah mertua ( senseviera trifasciata) pada komposit berpenguat CNTs dan non-CNTs terhadap uji mekanik (Bending dan Morfologi) dengan fraksi volume serat yaitu 40%, 50% dan 60% dan pengujian nya adalah kekuatan bending dan Scanning Electron Microscope (SEM). Hasil penelitian menunjukan dari spesimen continous memiliki nilai rata-rata tertinggi yaitu 18.01 Mpa pada fraksi volume serat 50% kekuatan bending 20.75 Mpa dan spesimen komposit flake medapatkan nilai rata-rata terendah sebesar 13.15 Mpa fraksi volume 50% kekuatan bending sebesar 8.41 Mpa.  Kata Kunci : Serat Sensivera, Fraksi Volume, Kekuatan Bending,dan SEM AbstractThis test aims to determine the effect of the volume fraction percentage of mother-in-law's tongue (senseviera trifasciata) fiber in CNTs and non-CNTs reinforced composites on mechanical tests (Bending and Morphology) with fiber volume fractions namely 40%, 50% and 60% and the test is strength bending and Scanning Electron Microscope (SEM). The results showed that continuous specimens had the highest average value of 18.01 Mpa at 50% fiber volume fraction, bending strength was 20.75 Mpa and flake composite specimens had the lowest average value of 13.15 Mpa, 50% volume fraction bending strength was 8.41 MPa.Keyword: Sansivera fiber, Fraksi volum, Flexural strength, SEM
