Tensile Properties of Highly Filled Magnetic Polymeric Composites

Abstract

The mechanical properties of ferrite filled thermoplastics at high filler loadings of 75-85% by weight are reported. Barium ferrite was used as the filler in the magnetic polymeric composites. Three types of thermoplastic elastomers, namely, styrenic, polyester-ether, and polyurethane were investigated as matrix materials. Low density polyethylene was also studied as a non-elastomeric reference matrix. The dependence of the strength at break, elongation and modulus on the matrix type, filler amount and strain rate is presented. The experimental results are compared with a few theoretical model predictions to explore the validity of the models at high filler loadings.

“…However, theoretically there are other factors that might influence tensile properties such as shape of particles, filler dispersion and filler-matrix adhesion. [24][25][26][27][28] The shape of the filler particle also may affect the properties of the composites. It is reported that spherical filler reinforced composite has higher tensile strength while the composite reinforced with irregular filler showed lower tensile strength.…”
