Material Characterization
Flexion Test
Sample 1 - no standard size
l - 20cm
t - av. 0.5cm
w - 2.02cm
ingredients:
recyclped paper and cardoard, water, cornstarch,
biochar
The Biochar cardboard shows moderate
stiffness and stability. Due to the irregular
composite, more tests are required to get
average measurements.
It is suitable for applications requiring resistance to bending and moderate stiffness such
as packaging, sound panels and 昀椀lter made
out of waste in the last recyling phase, such
as paper pulp and other organic waste that
cannot be re-introduced into a new cycle.
In general, the material ( not tested, though
) is very water absorbent and, due to the
the material is very irregular biochar composite, allows nutrient uptake
and capturing.
and even with out stress
seems brittle.
