Methods for manufacturing a carbon-containing glass material are disclosed. The method includes flowing a hydrocarbon gas and silane into a reactor, and providing an additive to the reactor. The method includes generating a non-thermal equilibrium plasma based on excitement of the hydrocarbon gas and the silane by a microwave energy, where the non-thermal equilibrium plasma includes a plurality of methyl radicals. The method includes ion-bombarding the glass material with at least the methyl radicals to create an interphase region. The method includes forming a plurality of FLG nanoplatelets within the interphase region based on recombination or self-nucleation of the methyl radicals. The FLG nanoplatelets may be dispersed throughout the interphase region in a non-periodic orientation that at least partially inhibits formation of cracks in the glass material. The method includes doping surfaces of the FLG nanoplatelets with the additive, and intercalating the additive between adjacent graphene layers within the FLG nanoplatelets formed in the glass material.

This piston includes a low thermal conductivity part comprising: a porous member made of a borosilicate glass that has a lower thermal conductivity than the piston base material made of an aluminum alloy material that is the base material impregnated into the porous member. A molded object obtained from a first powder (glass powder) and a second powder (sodium chloride powder) is put in hot water to dissolve away the second powder and form pores in the porous member. The aluminum alloy material is impregnated into these pores to unite the porous member to the piston base material. Furthermore, varnish containing polyimide, etc. is applied to the upper surface of the porous member and impregnated into the pores with a varnish impregnation device assisted by vacuum drawing and atmospheric pressure, thereby preventing the pores from remaining vacant. Due to this, deterioration in exhaust emission performance can be prevented.
