The optimization and streamlining of certain structures, parts manufacturing combined with high technical qualities (mechanical strength and physicochemical), recycling or reuse of solid wastes, reducing maintenance costs ... have motivated the use and development of specific materials whose composition and characteristics accommodate themselves to technological constraints.
The composite materials based on expanded perlite and unsaturated polyester resin (organic resins regenerated), were developed for this purpose. The basic idea is to combine in the same mass of different materials by their chemical and structural natures in order to increase mechanical, physical and / or chemical performance that can facilitate implementation. The composite material developed during this study is developed from an organic resin associated with expanded perlite and other mineral fillers including marble powder and / or cut plastic fibers.
Different formulations are made; taking into account both the proportion of expanded perlite, the nature of the inorganic fillers or reinforcements pledged that the thickness of the plates. The various tests carried out as mechanical and mechanic-chemical properties are reported.
