Thru-Hull Fittings in Sandwich Construction
From diabgroup.com

Through-hull fittings often introduce localized loads into sandwich panels, which are particularly sensitive to localized loads. In order to prevent damage due to these loads, the panels need to be constructed in such a way as to distribute the loads over the structure in a manner in which the sandwich panel is not damaged.

There are a number of ways to distribute the loads introduced by through-hull fittings.

These include using a high-density core, tapering the core to a solid skin or filling the area with reinforced putty.

If high-density plain Divinycell or Klegecell PVC foam core (> 130 kg/m3) is used throughout the panel, it is generally not necessary to modify the panel. A hole should be cut for the insert and the resulting edge should be sealed with a standard polyurethane or epoxy sealant. The fitting should be installed using a standard polyurethane sealant.

 


Products & Services
Polyurethane adhesives and sealants provide excellent flexibility, impact resistance, and durability. They are available in one-part or two-part adhesive systems.
Foam, honeycomb and core materials are plastics, ceramics or metals containing closed or open internal cells or pores for composites, tooling, modeling, insulation or floatation.
Specialty or proprietary products and accessories related to pipes, tubes, hoses, and fittings.
Industrial sealants are liquid or viscous compounds used between surfaces to contain fluids, prevent leaks, and prevent infiltration of unwanted material. They may also include compounds for filling gaps or seams.
Building insulation consists of all types of products and materials to prevent the passage of heat.
