The Implementation of Recycled Composite Powder in Rotational Casting.

Is it possible to grind up used or damaged composite products into powder and use it as filler in rotational casting? Rotational casting is a good candidate for this research method, since the percentage of recycled powder can be confirmed and maintained during this process. The exact amount of virgin plastic and recycled powder is placed directly into the mold and then closed, allowing all of the material to stay in the mold. The approach in this current study was not to return the fiberglass with polyester resin back to pre-mixed conditions, but to grind a used composite product into powder and use it as a filler. This concept could have a positive impact in two areas: it could reduce the amount of composite products in landfills or junkyards, and it can reduce the amount of virgin material needed to produce each new part. The samples with filler were evaluated using three methods: observational, drop test, and compression test.
