This is a part of my paper airplane project. As you know, whether the airplane could fly or fly higher or farther depends on the structure of the airplane and the materials of the plane. Like, for the real airplanes, airplanes are made of composite materials. this is because composites have high tensile strength, light in weight, resistant to corrosion and can easily be worked to any shape. The fundamental principles of paper airplanes are analogous with the real airplanes. So, this part is about the materials of making paper airplanes.
Here are my research about the materials we used to build a paper airplane.
