Polybeam enabled cabin top infusion

On February 5^th 2008 the Landing School of Boat Building and Design infused a cabin top for a small powerboat. Polybeam703 was utilized as an infusion flow reinforcement to allow rapid and uniform resin flow. Polybeam703 was layed directly against the plain balsa core to act as both a structural reinforcement and flow media. The z axis fibers improve damage tolerance and shear strength, while the smooth surface profile allows for excellent bond strength between the core and skins.

The laminate schedule consisted of the following materials and resin.

Vectorply E-LTM 1808
Polynova Polybeam703
1/2" Balsa
Polynova Polybeam703
Vectorply E-LTM 1808

Resin: Pro-Set epoxy 500-700 cps viscosity

Seven resin feeds were setup using Enkafusion strips as the resin carrier. Rope was used to facilitate the vacuum around the perimeter of the tool. The total infusion time was approximately 30 minutes.
