Method & Evidence

AimTo investigate the influence of composition and preparation methods on the adhesion strength between particle-filled composites (PFC) and fiber-reinforced composites (FRC) and to correlate these findings with mechanical properties and failure mechanisms.

MethodExperimental investigation with material characterization and micromechanical modeling.

ProcedureModel bi-material composite bodies were fabricated using different compositions of PFC and FRC. Mechanical properties were assessed using 3- and 4-point bending tests. Adhesion strength was measured using a modified pull-off test. Structural and fractographic analyses (TGA, SEM) were performed. Existing micromechanical models were used to analyze experimental data and establish relationships between material properties, geometry, and adhesion strength.

ContextMaterials science, composite manufacturing, biomaterials (dental prosthetics).
