Abstract: Abstract Mold‐cast, metal‐filled composites made of poly(methyl methacrylate) and aluminum or nickel exhibited electrical resistance qualitative behavior as predicted by the percolation and tunneling mechanisms. A precipitous change in resistivity of about 104 ohm‐cm was found at volume concentrations of filler in the range of 18.5 to 19.8 vol%. Details of the electrode system are given for making these measurements. Using different polymers does not change the resistance behaviour of the composite to any gre…
