However, the manufacture of the carriage requires a certain tooling and the weight of the veneer is high, and the surface treatment such as corrosion prevention needs to be performed on the metal. In order to meet the increasingly severe weight reduction requirement of the carriage, the sandwich composite plate is widely used in the existing carriage.
The more commonly used has a PP honeycomb sandwich panel and a foam sandwich panel:
pp honeycomb panel: as a carriage board, the material is a board with excellent compression resistance and impact resistance, and is non-toxic, environment-friendly and good in chemical property. The disadvantage is that the honeycomb core has poor processability and cannot be molded into a complex profile. Most importantly, the bending resistance of the honeycomb plate is mainly derived from the face plate, the bending resistance of the honeycomb is low, and the honeycomb core and the face plate are easy to delaminate. Therefore, the sheet is largely deformed when used as a side panel of a vehicle compartment.
2. Foam sandwich panel: polyurethane rigid foam is mostly adopted as a sandwich, the plate has low cost and simple forming, but the plate has the problems of flammability, toxicity and the like.
The wide application of composite material carriages is a great trend of carriage weight reduction, so the sandwich plate carriage is widely used at present. However, the sandwich panel has low bending resistance, and in order to solve the problem of large deformation of the side plates of the carriage, two main solutions are provided at present: (1) reducing honeycomb cells or thickening to increase strength; (2) and a reinforcing beam is additionally arranged on the carriage to reduce the deformation of the side plate. Both of these approaches increase weight and therefore a new side panel design is needed to address this problem.
