Hei, Pilots.
This video is a result of my one year long research and try-outs within production of durable and robust CF composite plate for FPV drone parts manufacturing.
I have pursued not only good strength property, but as well comparable and affordable low costs of end parts, that being produced.
As I have mentioned in series of Drone 101 short videos – biggest problem to get strong composite plate is to crate high bonding properties between CF and Epoxy resin. And I believe that latest version of drone arm made from Fully Woven CF composite is best solution to have strong yet inexpensive parts.
6 different type of arms were tested on the bending-braking bench with scales.
Video is a little bit long, in case you don’t want to watch it all, below are links to results of tests.
– 4 mm common Woven CF/ Uni-directional (UD) CF composite , with 0-90 degrees layers inside – https://youtu.be/-R6guFYo1hU?t=891
– 4 mm Woven CF / UD CF composite with 0-45-90 degrees layers inside, quasi-isotropic properties – https://youtu.be/-R6guFYo1hU?t=1104
– 4 mm Woven CF-Kevlar mix / UD CF composite, with 0-90 degrees – https://youtu.be/-R6guFYo1hU?t=1227
– 4 mm “Forged” Chopped CF composite – https://youtu.be/-R6guFYo1hU?t=1384
– 5 mm common Woven CF/ Uni-directional (UD) CF composite , with 0-90 degrees – https://youtu.be/-R6guFYo1hU?t=1549
– 5 mm Fully Woven CF composite – https://youtu.be/-R6guFYo1hU?t=1710

More episodes with more tests of other arms are coming.

Firstly I thank you for taking your time and effort looking out for the main subject of finding the strength properties of these Carbon Fibers. Nice approach with the test rig you have but I think its abit skewed for the results as each dimensions of the arm are different and the point where the arm angle of deflection supposed to be flexed should be equal distance across the arm for the pivot point (in this case, the vise?) . Weight characteristics of each CF properties given with the same dimension can be concluded with some useful findings taking all these target question as the approach. I’m already looking forward for your frames just because you seem to give alot of attention on the CF properties in making frames but like I said, your tests should conclusively mention which are best for certain purposes strictly for building such freestyle or racing rigs. As a vague personal opinion, honestly just out of all the arms, low cost : performance ratio will be the best one.
