1. What needs to be considered is the strength and bending stiffness. The component has the ability to withstand deformation and damage under the action of external loads. How to determine the load of the component so that it will not exceed the capacity range of the component? This is a problem that must be considered in the design of carbon fiber composite structures.

2. The effective combination of fiber and epoxy resin, as well as the mold starting position of carbon fiber, determines the strength and bending stiffness of the polymer material. In addition to the requirements for strength and bending stiffness, the reliability of polymer components must also be considered in the design. The molding structure is an important part of the design, and the excellent properties of the single-sided structure must be transferred to the composite structural parts. , try to minimize the mold removal in a single direction.

3. During the production process of carbon fiber composite components, it is unlikely that they will all adopt overall forming. The connection between components is required. Generally, carbon fiber composite materials have three interface modes, mechanical connection, powdery sand connection, and mixed connection.

4. The tensile fatigue limit of carbon fiber composites is better than that of metal composites. However, for composites, we must pay attention to the fatigue damage caused by shrinkage and cutting after impact and virtual beam cutting under load.
