The leading supplier of cutting edge technology

Fibre classification with the Phenom

Description: The Phenom™ has been used to investigate several different cutting edge applications in industries covering filtration, medical equipment, insulation, aerospace, and nanotechnology.

Recommended Product: Phenom G2 Desktop Scanning Electron Microscope

General Construction

The ability to observe general construction reveals information about fiber interaction, density, and count. Failure analysis of carbon fiberslike the one found in Figure 1 can help researchers improve the construction of their design to yield a stronger and lighter product.

Diameter

Fiber diameters can range from the micron to the nano scale. The diameters of fiberscan help forensics scientists identify crime scene evidence (figure3) as well as provide a quality control measurement for high-tech filtration devices (figure 4).

Morphology

Morphology is another characteristic that gives insight into manufacturing quality, surface roughness, and even fiberstrength. The images below depict fiberswith very different surface morphologies. The different morphologies of these fibersaffect their strength, interaction volume, absorption rate, and heat resistance.
