Application Prospects Of PVC Foam Core Structure

 The PVC foam core also has two properties and uses that the aluminum honeycomb core does not have: the use of thermal deformation ability can be used to manufacture curved structures; the use of low thermal conductivity and good thermal insulation advantages can be used to manufacture thermal insulation structures. .
  PVC foam can be deformed in two or three dimensions through a thermoforming process. The deformed curved surface can be either a deployable surface or a non-developing surface. The thermal conductivity of PVC foam is only 0.029W/m. K, so the heat insulation performance is very good.
  In the aerospace field, the PVC foam core sandwich structure can be applied to sub-load-bearing structures that do not require high shear rigidity, and can also be applied to non-load-bearing components, such as heat insulation cabins, multi-kinetic energy structures, etc., or in filled composites Material rods to improve its bending and torsion resistance. However, we must pay attention to the characteristics and requirements of structural products, especially the performance requirements related to the space environment in aerospace applications such as vacuum, thermal radiation, particle radiation, spacecraft equipotentiality, etc., to conduct sufficient analysis and verification to confirm Application of PVC foam core sandwich structure to the space environment adaptability.
