| Abstract: | Recycled plastics are considered low performance materials because their properties are expected to decrease drastically with
recycling. The objective of this study was to characterize a 15 wt.% glass filled polyethylene terephthalate (rPET-15GF) using
six recycle generations and four recycle ratios. Mechanical properties such as tensile strength, elastic modulus, and percent
elongation to failure of the PET composite were determined for various recycle generations and recycle ratios. Results show
that the mechanical properties of rPET-15GF decrease slightly per recycle generation. In contrast, thermal properties of rPET-15GF
were not at all affected by the recycling process. This data demonstrates that recycled glass filled PET can be used effectively
to fabricate components without significantly affecting their mechanical performance. |
