Boat Lamination Core Materials

Lindemann in the late 1930 s and 40 s.

Boat lamination core materials.

Used extensively in boat building. Core materials core mat is a low density non woven laminate bulker containing micro balloons. The core is extruded through a hexagonal honeycomb cell shaped metal die 8 ft wide and 4 inches high creating core with a cell size of 8 mm 0 32 inch and wall thickness of 0 005 mm 0 0002 inch. Right making the core out of thin laminations parallel to the field b green with insulation between them reduces the eddy currents.

Advanced core materials core materials are often used to reduce weight and increase stiffness. Some builders core the entire boat. Large molds allowed entire hulls to be made as one piece with no seams. The only way to build at that time used layers of fiberglass impregnated with an acrylic resin that hardened when cured.

Others construct with solid fiberglass from the waterline down and coring above and still others use some mix of coring and solid glass throughout the boat.
