Bamboo stick talk
After further discussion with fellow group members, the idea of using bamboo as the structural member material was brought up. Having little to no experience with bamboo, I decided to see for myself if this material could potentially be used in our pavilion. After a bit of shopping around at my local hardware store, Bunnings, I ended up buying some bamboo to get a feel for the material and to understand it a bit better. I bought two different varieties, bamboo canes ($7.40 for 10), which had a diameter of approximately 10mm and bamboo stake ($4.65 each) which had a diameter of approximately 20mm-30mm. Here are some of my observations with this material:
_due to its organic/unprocessed nature, there are some imperfections that come with the material, it has a tapering cross-sectional diameter (bamboo stake diameter ranged from 20–30mm) and is not perfectly straight
_From the quick testing I conducted, bamboo canes (10mm dia.) are very flexible, the bamboo stake (20mm dia.) are very rigid able to sustain a lot of force with any sign of struggle and slight flex
_Wood workability is consistent with other wood types, slightly harder to cut/drill.
The next stage would be testing this material with computerised machinery. I’ve been told by fellow peers that it is possible to maybe use the 3 point bend test machine in the engineering faculty on campus.
