Epoxy Resin Casting; Aluminium Filled

Aug 20 2001

Advantages

Highest oxygen index, good thermal conductivity, low mould shrinkage and density compared with other modified casting epoxy resins.

Disadvantages

Presence of aluminium fillers can sometimes inhibit cure. No resistance to acids. Lowest tensile strength, flexural modulus and notched impact strength and highest linear expansion compared with other modified casting epoxy resins.

How are Graphene Batteries Made?

The primary distinction between graphene-based batteries and solid-state batteries lies in the composition of either electrode. Although the cathode is commonly changed, carbon allotropes can also be employed in fabricating anodes.
