Sažetak
The mechanical properties of polyester composites reinforced by various combinations of glass fibre types were investigated. The samples were tested before and after the operation of the wet media in the salt chamber. Cross sections were recorded to determine the presence of cavities. It was concluded that the properties of composites depended not only on the number and type of reinforcement but also much more on the portion of cavities. It is concluded that the intermediate surface with a smaller portion of the cavities contributes to the compositions to be firmer and stiffer, but also fragile. As a result, the negative influence of water increases with the increase of porosity.
