“…Filler particles in dental restorative materials substantially enhance fracture toughness by increasing crack propagation resistance via several possible toughening mechanisms, such as crack deflection, crack pinning/bowing, matrix-filler interactions and crack bridging. 26,[43][44][45][46] Silanisation and nanoparticles improve the fracture toughness of dental polymer nano-composites through a combination of enhanced interface toughness through silanisation, crack deflection and crack bridging. 35 The fracture toughness of dental composites can be increased by improving the interfacial bond between the nanoparticles and matrix through a larger surface area-to-volume ratio and high particle strength.…”

“…PMMAseashell powder composites were evaluated for dental applications and the micro hardness values were noted to increase beyond 2% of the seashell powder. More significant gains in micro hardness values were noted beyond 4% seashell powder, while the values achieved were the highest at 12% seashell powder [10].…”

Singamneni et al., Bioceram Dev Appl 2018, 8:1 DOI: 10.4172/2090 Volume AbstractBinder-jet 3D printing responses of sea-shell powder based ceramic composites have been evaluated considering the material consolidation mechanisms and mechanical characterisations. Initial experimental printing trials are done manually, varying the composition of the composite powders from 5% to 50% of the seashell powder and the rest plaster. Overall, the seashell and plaster combinations worked well in terms of achieving the necessary green strengths within the binder-jet process conditions. Scanning electron microscopy and 3-point bending results indicated no significant loss of properties at lower levels of the seashell component, but the strength decreased beyond the 25% mark. The optimum levels of seashell powder are found to be within 15-20% by weight in terms of the best compression strengths. Neat sea-shell powder however goes too sticky immediately after the interaction with the binder liquid and does not show evidence of any binding mechanism that can be accelerated.

“…A maximum tensile strength of 8400N was reported at 5% sea shell filer content. Karthick et al [12] have studied the mechanical and wear properties of Sea shell/ PMMA bio composite at different filler loading. It was shown that the addition of sea shell nano powder at 12% loading resulted in better wear resistance of the composite which can be useful for dental applications.…”

The properties of polymer composites can be tailor made by incorporating suitable filler and fiber as a reinforcement in the polymer matrix. In this work, craft shell powder had been used a natural filler in the Epoxy resin and the composites were prepared at various proportions(4%, 8%, 12%, 16% and 20%) of craft shell powder using hand layup method. The specimens were subjected to various mechanical testing such as tensile test, flexural test, impact test as per ASTM standards. The test results revealed that particulate filler reinforcement resulted in marginal increase in tensile strength but the properties decrease at higher volume fraction of the fiber. But, the values of mechanical moduli had shown better improvement due to filler addition. SEM images were taken to analyse the interfacial bonding between the matrix and filler particles.
