Discussion Overview

The discussion revolves around the feasibility of creating a flexible cylinder with a diameter of 10cm and a height of 20cm, featuring numerous 0.01mm holes throughout its length. Participants explore material options and technologies that would allow for flexibility without compromising the size of the holes, particularly under high-temperature conditions of around 1000°C.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the required degree of flexibility and whether it needs to be elastic, suggesting that these factors may influence material choice.
  • Another participant emphasizes that the holes must maintain their diameter of 0.01mm and cannot be squeezed or diminished.
  • A participant suggests that ceramics may not be suitable due to the requirement for flexibility, while also noting that carbon-based materials are likely unsuitable at high temperatures.
  • There is skepticism about achieving such fine details (0.01mm holes) within a metal structure of the specified dimensions.
  • A potential solution of a ceramic/metal hybrid is proposed as a possible approach to meet the requirements.

Areas of Agreement / Disagreement

Participants express differing views on material suitability, particularly regarding flexibility and temperature tolerance. There is no consensus on a definitive solution or material that meets all specified criteria.

Contextual Notes

The discussion highlights limitations related to the feasibility of maintaining hole dimensions under flexing conditions and high temperatures, as well as the challenges of achieving such precise engineering in metals or hybrids.

Who May Find This Useful

hello

I need to create a structure that is a let's say 10cm diameter cylinder and 20cm height.

Inside the cylinder there will be numberous 0.01mm holes that will go through the length of the cylinder, so basically, there will be numerous tiny cylinders with 0.01mm hole that run across the 20cm height of the large cylinder.

So far so good, but I want it to be flexible, ie to bend, but I don't want the holes to be squeezed! I don't want the holes to be less than 0.01mm!

is this possible?

what material or technology can do that?

thanks!

How much do you need it to flex?
Does flexibility need to be elastic (return to original shape when not stressed)?
How many 0.01mm holes do you need?
At what temperature will this be operating?
 
it can flex a bit, like 30%, not much

it doesn't have to be elastic

the holes will be as many as possible to fill all the cross sectional area

temperatures around 1000 C

becarefull: the holes must not diminish in diameter, they must not be squeezed or shrinked
 
With flexibility, you're ruing out ceramics.
With 1000 C, I think you're ruling out anything that's carbone-based (plastics etc).
You're left with metals.
With my current knowledge, I doubt such fine details can be had on a such a scale (0.01 mm X 100 mm tunnel within a metal?).
I'll be curious if you find anything.
 
maybe a ceramic/metal hybrid?
