BACKGROUND AND AIMS Effect of surface treatments on repair bond strength of aged composite resins might be different due to their dissimilar fillers. The aim was to evaluate the effect of different surface treatments on repair micro-shear bond strength (µSBS) of silica- (Spectrum TPH) and zirconia-filled (Filtek Z250) composite resins. MATERIALS AND METHODS Twenty-seven composite resin blocks...

In order to study the mechanical performance and friction slip mechanism of interface a composite timber column under inclined deformation, unilateral contact model an ancient deformation is proposed in this paper. According limit inclination angle point surface, failure modes combination’s can be divided into three stages: fully sticky stage, partially stage sliding stage. The theoretical resu...

The present article uses the finite element analysis (FEA) software ABAQUS to model a bamboo-based advanced composite column for construction. Different numerical models were analysed be able predict behaviour of tested by same group. Bamboo-based composites maintain inherent excellent mechanical properties raw bamboo whilst adding certain degree processing and engineering. Thus, individual sam...
