| Summary: | Fiber-reinforced composite (FRC) is a material composed of a matrix and a
reinforcing fiber. The fiber widely used for the manufacture of fixed partial dentures
is a synthetic one. Sisal (Agave sisalana) fiber is used as a reinforcing material on
FRC, for it is cheap and it comes from the renewable resources. Alkalization on
sisal fiber can increase adhesion between the fiber and matrix. This can increase the
mechanical strength of the FRC. The purpose of this research was to explore the
difference between the compressive strength of the FRC with alkalized sisal fiber
and that of the FRC with non-alkalized sisal fiber.
The material of this research was FRC with matrix consisting of flowable
composite resin (Master Flow, Brazil), sisal fiber (Balittas, Malang), and 5% NaOH
solution. The research sample which was the FRC with sisal fiber (cylindrical, 8mm
height, 4mm internal diameter) was cured using a light curing unit for 20 seconds.
The number of the samples was 8 and they were divided into two groups |
