Vacuum bag? $300 box?

@datzfast Think of it in terms of a truss...If you went ahead and bent one of the members then the structure has become weaker...The place where the truss was bent is the weak point where the truss is likely to fail...Your more than welcome to make test pieces and do the tensile testing yourself...but you won't find spread sheets out there that tell you this...There are a lot of factors that go into making composites(Material Science) which includes the raw materials and the curing process.

@xxsaranglubxx just as i suspected no one has the answer, its weaker this is whiy and no we dont know how much weaker. lovely.
-
@datzfast The strength of the part is basically determined by the direction of the carbon fibers. There are tensile stresses and compressive stresses on a part so carbon fabric is layed in a way that the fibers are oriented parallel to the direction of the force so that the fibers can counter the forces being applied to it after a part has cured. By using a squeegee/brush the weave can be distorted making a weak spot. Rollers squeezes the epoxy while mantaining the weave configuration.

fuck, that looks bad!
-
worst job i've ever seen! :D
-
next make a carbon fibre burger
-
I still don't know what it is for, but I enjoyed the video anyhow.
-
I wasted 15 minutes of my life for you to make a box?! Gosh, I could of been on wikipedia and then writing up my assignment. FFS!
-
@xxsaranglubxx what was the measurable difference in strength between squeegee and brush roller applications? and where may i find this data set?
i am more than just curious.
