EXTREMELY LIGHTWEIGHT MATERIAL
Polyester composites are lightweight, especially in comparison to wood or metals. Lightness is an important and useful feature of a material, especially in the automotive, nautical, or aviation industry.
MECHANICALLY FIRM MATERIALL
Mechanical firmness of polyester composites (depending on the manufacturing process) can greatly exceed the firmness of aluminium or steel. Unlike metals, reinforced polyester is designed to be firmer in a specific direction or line (depending on the needs and purpose of the final product).
MECHANICAL FIRMNESS AND WEIGHT RATIO
Unbeatable ratio between the mechanical firmness and weight is a great advantage of polyester composites compared to other materials (for example metal which is firm, but also much heavier). Reinforced polyester has the most favourable ratio between the firmness and weight if we compare various materials which are being used in different industries today, therefore it is especially important for the production of different types of vehicles and vessels, as well as in other production processes where the lightness of the material plays a key role. Polyester composites are designed in a way to ensure greater firmness of a material in a specific line, whereas metal structures, for example, need to be additionally reinforced in critical spots with a thicker layer of the material to get the same result, which consequently affects the weight of the structure.
