3M Structural Honeycomb Core Materials
At 3M Corporation we have continuously challenged the traditional thought in core materials, and succeeded, judging by the number of material industry awards bestowed upon our core products incorporating our patented technology.
It is possible to obtain high core strength, low material
weight, cost-effective core materials; it is also possible to
obtain simultaneously high material impact resistance, virtually
zero water absorption, high dimensional thermal material
stability, sound and thermal insulation...
Not surprisingly the competition never wanted you to know about our core materials. It gives us the greatest pleasure to present 3M Structural honeycomb core materials, and other associated products and services offered by 3M Corporation.
Sandwich panels mimic the characteristics of an I-beam, using flanges to support tensile and compression loads, with a shear web joining the flanges. Composite skins constitute the flange portions of the I-beam. Instead of using narrow webs, as is done on the centerline of an I-beam, low-density core materials are used throughout the space between two material skins. The preceding schematic demonstrates the effectiveness of a honeycomb core panel (Al) compared to a solid aluminum material sheet in 1/4-inch thickness. By using a core material to double the thickness, the flexural stiffness is increased seven (7) times at almost the same materials weight! The mechanical efficiency of this cored sandwich material can be dramatically increased by increasing "Core Thickness".
3M’s Honeycomb core structure is a material ready to handle all kinds of stresses due to it’s unique structural integrity properties.
A sandwich construction with 3M Structural Honey comb is more impact resistant than a single skin laminate of equal or higher weight.
3M Structural Honeycomb Core structure is made of polypropylene copolymer.
With a natural harmonic range of 125-150 Hz, polypropylene is known for its excellent structure bourne vibration damping properties.
3M Structural Honeycomb Core structure decreases weight while increasing stiffness and strength.
