Electrical properties of conductive polymers under stress
Statement of the Problem: With the growing field of application of composites as replacements for hitherto metallic
applications, the need for conductive polymers has increased. In fact, although composites can often replace metals
with gains in weight, some applications require electrical conductive properties. Metallic films and grids have been
envisaged and sometimes applied, but the high density of metals still imposes a significant increase in weight. The use
of electrically conductive polymers might provide an interesting solution, but there is scarce information about the
electrical behavior of such polymers when included in structural members. Additive manufacturing is a technology
that enables the construction of graded materials. The specimens where built with layers in conductive PLA and regular
PLA. The purpose of this study is to describe the tests and results obtained while measuring the electrical conductivity
of polymers under stress.
Methodology & Theoretical Orientation: Electrical resistance of specimens was measured under different load
conditions. The specimens were obtained by fusion deposition modeling; since this process delivers non-isotropic
parts, the influence of manufacture process parameters was also tested. Specimens were tested for uniaxial and bending
behavior.
Findings: A database of values of the electrical conductivity of the studied polymers was obtained and the influence of
the manufacture parameters on this property was studied.
