Abstract

See full text

A lightweight polymer-based composite product may include a polymer material body and a lightweight filler material that is embedded in the polymer. The polymer material body may be an in-situ polymerized polymer formed via casting of a reactive resin in a mold. The polymer may have a density of at least 1.0 g/cm3. The lightweight filler material may be concentrated on at least a portion of a first surface of the polymer material body. The lightweight filler material may have a density of between 0.1 and 1.0 g/cm3. The lightweight polymer-based composite product may have a density that is less than a comparable product that consists mainly of the polymer.
