The Composite Materials Based on Expanded Perlite and Unsaturated Polyester Resin: A Chemical Analysis Technique

Abstract

For this objective, composite materials based on unsaturated polyester resin and expanded perlite (organic resins that have been recycled) were created. The use and development of a various materials, whose composition and properties lend themselves to technological constraints, has been motivated by the optimization and streamlining of certain structures, parts manufacturing combined with high technical qualities (mechanical strength and physicochemical), recycling or reuse of solid wastes, and lowering maintenance costs.

The basic idea is to combine in the same mass of different materials by their chemical and structural natures aiming to increase mechanical, physical and / or chemical performance that can facilitate implementation. The composite materials developed during this study are developed from an organic resin associated with expanded perlite and other mineral fillers including marble powder and / or plastic wastes fibers.

Different formulations are performed, taking into account both the proportion of expanded perlite, the nature of the inorganic fillers or reinforcements. The various tests carried out as mechanical and mechanic-chemical properties are reported.
