Mechanical Properties of Nano-Laminar Glass/Metal Composite
A nano-laminar glass/metal composite was fabricated. Glass flake powder coated with silver was used as the raw material, and was sintered by hotpressing. Samples fabricated in the optimum condition had a dense, laminar microstructure originating from the aligned flake powder. The result of a three-point bending test for the samples suggested that the alignment of the powder was essential for fracture behavior: When the powder was aligned in advance during the green sample fabrication, the sample fractured stably after the maximum load, while the samples fabricated by simple hotpressing of the powder without pre-alignment fractured unstably. Work of fracture of the sample in which the powder was well aligned was measured with chevron notched specimens; a significantly high value of about 300J/mm2 was obtained.
