PENGARUH POSISI FIBER TERHADAP KEKUATAN FLEXURAL FIBER REINFORCED COMPOSITE JENIS ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE (UHMWPE)

Fiber reinforced composite (FRC) was a material made of matrix that reinforced by fine thin fibers. In fixed partial denture bridge adhesive with FRC, fiber could be positioned in different positions. One of important factors influencing the mechanical properties of FRC was position of fiber. The aims of this study was to determine the effect of fiber position on flexural strength of UHMWPE fibers. Speciments in this research were FRC with UHMWPE fibers (Construct KerrLab, USA). Bar shaped speciments with a size of (25x2x2)mm, cured with ligh curing unit in 40 s (n=4). Fibers were placed with three different position
