Composite sandwiches have been developed and produced for various aspects of life today. Unsaturated polyester content combined with pin from plants such as the pin of bamboo plants that grows around us and polyurethane rigid foam as the core. The method of sandwich composite joints is very important when applied to construction such as window panels, walls, roofs, floors, and others. The metho…
Sandwich construction becomes an option on structures that have high stiffness with lighter weight. The principle of sandwich structure is to combine composite skin with a high elastic modulus with a lightweight composite core to obtain a rigid combination, strong but lightweight materials. However, the core made of polyurethane foam has a compressive strength and modulus close to zero in the d…
