Stronger and Lighter
In simple terms, the core increases the flexural stiffness of a
sandwich panel used in hulls, decks and bulkheads by effectively
increasing the distance between the two stress skins, much
like an I beam. Marine honeycomb cores also effectively provide shear
resistance, a key component to overall flexural stiffness.
Stiffer and Lighter than Single Sheet Laminate
The stiffness of honeycomb laminations and Plascore Board™
allows boat builders to use less material, reducing weight while
increasing speed and cargo capacity. Stiffness increases exponentially
compared to single sheet material. The use of honeycomb core(s)
creates a dramatic increase in stiffness with very little weight gain.
Save Weight and Money
The best of both worlds: Plascore PP Honeycomb and Aluminum
Honeycomb are not only lightweight cores, they are more cost-effective
than balsa and foam and do not absorb water, while Nomex® and
Kevlar®, typically used in racing boats for their aerospace qualities, are
extremely light, with high temperature stability for prepreg applications.
The value of each core must be weighed in a ‘go-to-market’ strategy:
which core delivers the best performance, is most compatible and is
readily available at a competitive cost for the specific application?
Continued Performance after Failure
Most marine core materials respond similarly to stress under normal operating
loads. As loading increases the core begins to flex to accommodate the
increase in shear stress on the core. Unlike other core materials that
reach an ultimate yield stress and fail catastrophically, honeycomb,
and in particular Plascore PP Honeycomb, continues to respond
and perform. This continued response indicates the ability of the
honeycomb to absorb energy even after ultimate yield strength failure.
