Carbon fiber products in the plate, pipe, roller is the most used several, these carbon fiber products are rarely used independently, often combined with other parts, which involves the connection problem. Bonding, mechanical connection or embedding, need to be decided according to the actual situation, may be in the plate, pipe holes, then these pores will affect its own physical structure and mechanical properties?
Will the opening of carbon fiber plate damage its physical structure and mechanical properties?
Will opening holes damage the physical structure of carbon fiber plates?
From a physical point of view, the opening of a hole in a carbon fiber panel does weaken its structural integrity, but the degree of impact depends on a variety of factors, such as the size, location and shape of the hole, as well as the specific design and intended use of the panel.
The stability of the physical structure of the carbon fiber plate is the key to the final use, so the conclusion of whether the opening will affect the physical structure should not only be judged from the appearance, but also be demonstrated from the actual use effect.
The strength of the carbon fiber plate comes from the continuous fiber embedded in the resin matrix, and the punching operation is actually to interrupt or remove the fiber in the area around the pores, resulting in local physical structure damage, and the carrying capacity of the plate is reduced, but if the pore density is low and the aperture is small, this loss and reduction may not affect the final use of the carbon fiber plate.
Will the opening of carbon fiber plate damage its physical structure and mechanical properties?
Can the opening of carbon fiber plate affect its mechanical properties?
Above we also said that the physical structure will affect the final use of carbon fiber plates, which may contain the problem is that the opening is unreasonable, after the destruction of the physical structure, the mechanical properties are also greatly reduced. This problem will be encountered in actual operation, want to avoid this problem, first need to plan in the design stage, pore diameter size, location, density, etc., need to be deployed in advance.
Unreasonable opening operation will indeed affect the mechanical properties of the carbon fiber plate, pull down the upper limit of the performance of the carbon fiber plate, so the original intention of the selection of carbon fiber plate is broken. The existence of unreasonable pores often affects the mechanical properties of carbon fiber plates from the following angles.
1, stiffness and strength: Holes in carbon fiber plates reduce their overall stiffness and strength because they create stress concentrations around the edge of the hole. Stress concentration can cause local failure or deformation, resulting in a weaker structure than an unperforated plate.
2, Bearing capacity: The presence of holes will reduce the bearing capacity of the plate, because the load is no longer evenly distributed across the surface. The remaining material around the hole needs to withstand a greater proportion of the applied load, which can lead to increased stress and potential failure.
3, fatigue resistance: the hole can act as a stress concentrator and cause cracks, especially under cyclic load conditions. This reduces the fatigue resistance of the board, making it more prone to failure over time.
4, impact resistance: the presence of holes will reduce the impact resistance of the carbon fiber plate, because the energy absorption capacity is reduced. Holes create weak areas where stress can be concentrated during impact events, potentially leading to premature failure.
In fact, it is not only the operation of opening holes, in fact, many processing methods, such as cutting, hollowing, etc., improper operation may cause the performance of carbon fiber plates and other products to decline. The yield of carbon fiber products is much lower than that of metal products, which is one of the key reasons.
