Abstract
A study was conducted to investigate the impact strength of basalt fibres in vinyl ester resin, a composite laminate material used for the design of marine vessels. The basalt/vinyl ester laminate material was dynamically loaded with a Ceast/Instron falling weight machine, using a 3.6 kg cylindrical impactor with a 19.8 mm diameter hemispherical nose. Impact tests were conducted at various energy levels—up to complete penetration—to obtain the full load–displacement curve, identify the material’s penetration energy, and investigate damage initiation and propagation. After the impact tests, the internal damage of each specimen was evaluated using the non-destructive Ultra Sound technique.
