The main objective of the research was to replace the commonly-used pieces in railways transportation, specially railways insulator with phenolic/fiberglass nanocomposite. The insulator should have high environmental resistance because it is imposed to various climate conditions during the year.

According to the researchers, the proposed pieces can be used in the body and top of spaceships and spacecraft, which require high strength at harsh environmental conditions, as well as in railways as a composite insulator. The reason is high resistance of phenolic resin against temperature and pressure.

Observations of the researchers showed that the use of clay nanoparticle in the structure of phenolic resin significantly increases the mechanical properties even at low compositions, to the extent that using only 2.5% of the weight of both types of clays in the composite structure results in 45% increase in the value of elasticity module and also an increase in tensile and shear strengths and impact resistance. On the other hand, the replacement of linen fibers that are widely used in railways with fiberglass results in an increase in the strength and environmental resistance.
