Abstract
Glass reinforced plastic, so called GRP, is a composite material made of glass strands called fibbers woven together to create a flexible fabric. GRP is a lightweight material with many and diverse applications ranging from the manufacture of reservoirs for different liquids to the manufacture of boats, yachts, chairs and even children playground furniture. The behaviour of this material under static and dynamic loads is still raising interest from the scientific community and a large number of researchers. This continued interest is due to the material versatility for different applications depending on its manufacture process that has a significant weigh-in in the material mechanical properties. These resulting mechanical properties need to be carefully analysed and benchmarked prior to using the obtained material in commercial applications. The scope of this research study is to analyse the behaviour of glass reinforced plastic plate panel with reinforcements on one and two directions under static and dynamic loads employing both experimental and numerical methods for results validation. The methods used in this research study for the dynamic loads can also be applied successfully to other composite materials. Additionally, the stress plots have been analysed in iteration in order to ensure the most optimal reinforcement pattern.
Highlights
Composite materials are obtained by combining two or more base materials
The method provides the possibility of programming the composite material mechanical properties from the concept stage, resulting in a final material net superior to the base materials with applications in the aerospace industry, car manufacturing, etc. [1, 2]
GRP has been successfully used for the construction of leisure boats, rapidly becoming the standard material used in this sector [5, 6].Due to the fact that composite materials are diamagnetic, they are applicable for warships (Figure 1), and medium sized yachts up to 67 m length (Figure 2), etc
Summary
Composite materials are obtained by combining two or more base materials. The mechanical properties of the parent materials are combined resulting in a superior material with enhanced mechanical properties. The method provides the possibility of programming the composite material mechanical properties from the concept stage, resulting in a final material net superior to the base materials with applications in the aerospace industry, car manufacturing, etc. Shipbuilders are always looking to improve their traditional shipbuilding methods and to replace the materials used, such as steel, with better performing materials To this date, GRP has been successfully used for the construction of leisure boats, rapidly becoming the standard material used in this sector [5, 6].Due to the fact that composite materials are diamagnetic, they are applicable for warships (Figure 1), and medium sized yachts up to 67 m length (Figure 2), etc
