Hi, I am a student who is currently undertaking a finial year project, I am researching the potential use of carbon fibre rods being used as reinforcement for concrete beams. I have found a company which does this with glass fibres however I would also like to look into carbon fibre. I would like to know if it would be possible to produce rods with a helical pattern/rough surface texture for a given length. Please see image below.

Hi Sam,

From reading your post I'm not clear on whether you're asking more generally whether such production is possible or whether you're asking specifically whether it's something that we could offer? - If the question is the former then yes, there is no reason why the same manufacturing process use to produce those glass fibre reinforcement bars couldn't be used to produce carbon fibre versions. If you're actually asking whether we (Easy Composites) could do it then the answer is no, I'm afraid. The carbon fibre rods that we sell are manufactured using a conventional pultrusion process which, on its own, could not produce the helical pattern or rough surface texture.

I am aware that carbon fibre rods are already used quite extensively as reinforcement for concrete, plaster and similar (for use in applications subject to high levels of corrosion or strong magnetic fields) and as such there are a number of manufacturers already producing such bars. Googling Carbon Fibre Rebar pulls up various suppliers on Alibaba and similar, such

I hope this helps and wish you all best with your research.
