UV Aging Behavior of Functionalized Mullite Nanofiber
In this study the effect of accelerated ultraviolet (UV) aging on the properties of polypropylene (PP) as well as its blend with PP-graft-maleic anhydride (PP-g-MA) and composite with amine-functionalized mullite nanofibers (AMNF) was compared. Solid-state NMR exhibited some changes in the macromolecular chain structure after aging whereas the formation of degradation products was

Preparation and Characterization of SiC Whisker-Reinforced
SiC porous ceramics (SCPCs) were fabricated by a dry press forming method and in situ reaction-bonding technique using ZrO2 as sintering aids activated carbon as pore-forming agent and SiC whiskers as reinforcing agent. The effects of the amount of SiC whiskers on the porosity bending strength microstructure and gas permeability of the SCPCs were investigated. The results showed

Toughening Mechanism of Mullite Matrix Composites A Review
Mullite has high creep resistance low thermal expansion coefficient and thermal conductivity excellent corrosion resistance and thermal shock resistance and plays an important role in traditional ceramics and advanced ceramic materials. However the poor mechanical properties of mullite at room temperature limit its application. In order to improve the strength and toughness of mullite the

Highly porous mullite particulate filter substrateGEO2
The mullite fiber wall traps particulates in its pores as shown in block 459. The gas is then exhausted into another channel as shown in block 461 and vented out the outlet port as shown in 471. If the filter has a flow-through filtering then the gas is passed along a porous wall comprising mullite fibers are shown in block 464.
