The purpose of this study is to design and select alternative materials for professional sports competitions from easy to repair polymer matrix composites that can offer high performance and lightness,
have the optimal resistance to corrosive environments, and have ideal impact strength. The study employed 3D PET (Polyethylene terephthalate) foam as the core material and carbon and glass fiber reinforced epoxy
matrix as the surface of sandwich composite structure. The sandwich composite samples were created by layering different combinations of twill (T) and unidirectional (UD) textiles manufactured with carbon and
glass fibers. Flexural and impact tests were used to evaluate four distinct sandwich composite combinations. Four different sandwich composite combinations were produced and evaluated using flexural and impact
tests. The sandwich composite surfaces were created using a combination of 2 layers of carbon twill fabrics (T1), 3 layers of carbon twill-UD-twill fabrics (T2), 3 layers of glass twill-UD-twill fabrics(T3) and 3 layers
of carbon twill-glass UD-carbon twill hybrid fabrics (T4). The results indicated that the T3 carbon samples had the highest flexural strength, while the T1 carbon fiber-based twill sandwich composites had the lowest
results. Additionally, it was observed that the T4 hybrid samples had a higher impact strength compared to the other samples. Overall, the test results revealed that the T2 carbon sample had the most suitable
mechanical properties and was the best option for meeting the design needs of a performance-oriented racing canoe.
