Anybody know the young's modulus for bamboo?

[Docta]

I have decided on using vertically laminated bamboo for the cores on my planned skiis, and need to predict flex patterns. Ive leeked all over the web for this value, no luck... anyone on here no this number so I can add it to the ski flex prediction program?

it's about 18.000 to 20.000MPa, i can sent you a complete data sheet from a materials database i work with if you want. Just pm me

Can you hit me up with a link to the bamboo you plan on using, for some personal use... Thanks bro

I am getting V-lam bamboo ply at 1/2 inch from a cabinet maker friend for 150 for 4x8'.... looking for cheaper If I can find it.

Young's modulus along fibres: 20.6GPa
Ultimate Tensile Strength along fibres: 193MPa
UTS transverse to fibres: 8.1MPa
UCS along fibres: 68.4MPA
In-plane shear strength: 9.2MPa

I'm not convinced by the experimental methods they used for determining strength (particularly transverse tensile strength) and think that the actual values would likely be higher than measured.

Also, there are different types of bamboo and this paper didn't say which they were using. In addition, the properties will depend on the age of the bamboo and whether the bamboo comes from the top or bottom of the reed. Can't remember where I read that but I know I did sometime.

For cabinets and surface finishes that may sustain damage during long use, serviceability is a consideration. In case of damage, solid wood can be repaired by a qualified furniture refinisher, other than the manufacturer, to achieve a perfect match to the surrounding finish.

Is it rude to ask which flex prediction program you are using? cheers!

thanks for sharing
