Several types of commercial-based thermoplastic-elastomer films, such as polyurethane elastomers, polyethylene-based ionomers and polyamide elastomers were compared as the interleaving materials for composite laminates. The damping properties of the composite laminates with Excellent mechanical properties of carbon-fiber-reinforced plastic material (CFRP) demonstrates many possibilities in industries using lightweight materials, but unlike isotropic materials, such as iron, aluminum, and magnesium, they show direction-sensitive properties, which makes it difficult to apply for them.

The ratio of the compressive strength to the tensile strength is smaller for graphitized fibers than carbonized fibers. Pitch-based carbon fibers have even lower compressive strength than PAN-based fibers. Moreover, the compressive failure strain is much lower for pitch-based carbon

38 TABLE 3 Experimental Results on the Effect of Fiber Orientation on the Damping Loss Factor of Boron Fiber Reinforced Epoxy Lightweight carbon fiber reinforced polymer composite structures with high stiffness are at risk of resonant vibration. Our study proposes a methodology to reduce this risk by passively improving the damping ratio of carbon fiber reinforced polymer composite structures. Excellent mechanical properties of carbon-fiber-reinforced plastic material (CFRP) demonstrates many possibilities in industries using lightweight materials, but unlike isotropic materials, such as iron, aluminum, and magnesium, they show direction-sensitive properties, which makes it difficult to apply for them.
