If raw carbon fiber has strength of say 4000 mpa, how come it is reduced when put in epoxy laminate to become only 950 mpa?
Carbon fiber raw strength refers to the strength of individual carbon fibers, while laminates refer to multiple layers of carbon fibers that are stacked and pressed together. Laminates are stronger than raw carbon fiber alone because they are reinforced with additional layers and bonded with resin.
Laminates are generally stronger than raw carbon fiber. The bonding of multiple layers of carbon fibers in different orientations distributes the load and increases overall strength. However, the specific strength of laminates can vary depending on the number of layers, orientation, and type of resin used.
Carbon fiber is one of the strongest materials available, with a tensile strength 5 times greater than steel and a stiffness 2 times greater than aluminum. However, its strength can vary depending on the quality of the fibers, the manufacturing process, and the design of the final product.
Yes, both carbon fiber raw strength and laminates have a wide range of applications. Raw carbon fiber is often used in high-performance sports equipment, such as bicycles and tennis rackets, while laminates are commonly used in aerospace and automotive industries for their strength and lightweight properties.
The strength of carbon fiber and laminates can be tested through various methods, including tensile testing, compression testing, and flexural testing. These tests measure the force required to break or deform the material and provide valuable information about its strength and stiffness.
