The major goal of this research is to use nonlinear finite element analysis to investigate the strengthening of reinforced concrete (RC) beams with CFRP. The models were created using ANSYS finite element analysis software, which was used to investigate the influence of key parameters on the response of reinforced RC beams under flexure and shear. Seven models were created, four for flexural strength and three for shear strength, taking into account the effects of two primary parameters: the number of CFRP layers and CFRP strengthening by continuous U-wrapping. The ANSYS results were in good agreement with the previous research's experimental findings. The ultimate capacity in shear and flexure improves for strengthened RC beams with CFRP layers and U-wrap, with U-warp proving to be more effective than CFRP layers.

I can't really find anything helpful online, does anyone know where I could buy carbon fiber reinforced polymer. I have a club at my school where we build rc aircraft and we're looking to build the body out of this material because of its strength:weight ratio. Thanks!
As I've understood, carbon fiber is annoying to cut, hazardous to breathe and nearly impossible to combine. So I'm not looking to build the entire case out of it.
I am, however, interested in possibly using a carbon fiber structure to build around. Most of the case skeletons today seem to either be wobbly and unstable or then just incredibly heavy.
Would using a carbon fiber skeleton be a good/bad idea? Where could i get ahold of a structure like this without having to make it myself?
Looking for any tips on how to cover and aluminum space frame chassis in carbon fiber sheeting. The frame itself is made of 1''OD by .75''ID Aluminum 6061 tubes. I really just want to know if its possible, and if so what would be the best way to go about it. Any tips are appreciated
This is the best tl;dr I could make, original reduced by 86%. (I'm a bot)

> MDOT is deploying the materials strategically, using them on higher-volume routes: two bridges are currently being built with carbon fiber reinforced beams as part of MDOT's massive I-94 modernization project in Detroit.
> Since 2001, MDOT has been collaborating with Lawrence Technological University in Southfield on researching carbon fiber reinforced polymer materials in concrete bridge beams.
> To understand why carbon fiber is such a game-changing technology, it helps to understand how modern bridges are built to withstand the loads of thousands of vehicles every day and extreme temperature changes for decades.
