Effects of Fiber-Resin Interface Property on Shape Recovery and Mechanical Properties of Denture-Base-Resin Matrix Smart Composite

Article Preview

NiTi shape memory alloy fiber-embedded denture-base-resin matrix smart composites were developed as a new denture base material for a “smart denture”, whose shape could be recovered simply by heating after fracture. Three types of fiber surface treatment were applied for the composites and their properties were evaluated by the fiber-pull-out test and bending test, and shape change after repair was examined. A high interface debonding strength increased the fracture strain but did not affect bending strength, and a low interface sliding strength minimized shape change after repair. These results indicate that the fiber-matrix interface with a strong bonding but easy sliding after debonding could improve the preciseness of “smart repair”.
