Abstract
Several studies have reported the use of conductive Poly Lactic Acid (PLA) plastics in
various industries; however, there are limited research studies on magnetic PLA. In this
research, PLA with electrical and magnetic properties are fabricated. In addition, a neural
network is also developed to estimate the parameters required to fabricate a given composite
PLA with unique electrical and magnetic properties. Carbon and iron particles are used as
electrical and magnetic reinforcements during the fabrication of the composite PLA plastics.
The properties of the composites are characterized using an impedance analyzer. The
characterization data from the experiment show that the conductivity and magnetic properties
of the pure PLA is improved by combining it with carbon and iron particles. Furthermore, it
is observed that, at a certain weight percent of carbon, the conductivity threshold is reached.
Therefore, any further increase in carbon does not significantly improve the conductivity of
the composite PLA. In addition, the developed neural network is able to estimate the
parameters required to fabricate a given composite PLA with acceptable accuracy. Between
80 - 90% of the neural network predicted output parameters are within an error of +/- 10% of
the actual experimental values.
