This study was conducted using epoxy resin as ligature and midrib lontar fibers (borassus flabellifer) as brace. Composite was made by varied fiber volume fraction 10%, 30% and 50% with length variation 10 mm, 20 mm, and 30 mm. The composite production used hand lay-up method. The test result showed the highest composite tensile strength about 31.607 Mpa in volume fraction 10% with fiber length 30 mm. The lowest composite tensile strength was about 16.855 Mpa in fiber volume fraction 10% and 20 mm in fiber length. Moreover, the highest composite impact strength was 0.00163 J/mm in fiber volume fraction 50% with fiber length 30 mm and the lowest impact strength was 0.00214 J/mm 2 in fiber volume fraction 10% and 10 mm fiber length. The kind of composite fracture tended to have brittle fracture with mechanism of fiber pull out.
