Carbon fibre has good tensile properties, so it is best wrapped around an outer convex surface where tension forces in long fibres will not cause delamination. Internal concave surfaces tend to be compressive so it is the glue or filler that will be more important, held in place by short fibres as reinforcing.kolleamm said:I have a fragile plastic piece and I would like to coat the inner walls with carbon fiber, ...
I do the same thing with carbon fibers and high strength low viscosity epoxe. If the epoxe bonds well to substrate (always a crapshoot with plastic) the result is remarkably strong.Baluncore said:Carbon fibre has good tensile properties, so it is best wrapped around an outer convex surface where tension forces in long fibres will not cause delamination.

Small plastic items break after becoming brittle with time. I sometimes repair them by reassembling the parts with cheap superglue. Then I wind a Kevlar fibre around them, backwards and forwards to make a very thin outer sock of cross-hatched thread. One drop of fluid superglue on the Kevlar wicks through to make a very strong exoskeleton. The superglue, = cyanoacrylate, chemically bonds with the Kevlar, = aramid.
I get the Kevlar fibre from scrap cable. Make sure you are not touching any fibres as the superglue wicks in, or you will very rapidly become part of the exoskeleton.
Maybe de-water the soil around your basement. If you have a sump pump there, the perforated pipes that run around the foundation may have collapsed/filled with stuff, raising the water table.hutchphd said:...70 year old block basement walls which had started to bow a bit...small gaps in the horizontal mortar lines.
Actually I had recently had a galvanized intake water pipe replaced which clearly created some leakage and backup outside. This likely caused the issue but is copacetic now. Vertical carbon fiber has made wall rock stable. Good call, thank you!Tom.G said:Maybe de-water the soil around your basement.

Many plumbers can send a video camera thru the pipe to check for blockages. Not cheap, but cheaper than a collapsed wall.
It is not recommended to use just any type of glue with carbon fiber fabric. Certain types of glue may not bond well with the material and could result in a weak or ineffective bond. It is best to use a specialized adhesive that is designed specifically for use with carbon fiber fabric.
Yes, mixing carbon fiber fabric with glue can affect its strength. The type of glue used, as well as the quality of the bond, can impact the overall strength of the fabric. It is important to use a high-quality adhesive and to follow proper bonding techniques to ensure the strongest bond possible.
There are several factors to consider when choosing a glue for carbon fiber fabric, including the type of material being bonded, the strength and flexibility needed, and the application method. It is best to consult with a specialist or do thorough research to determine the best adhesive for your specific project.
No, it is not recommended to mix different types of glue together to bond carbon fiber fabric. Each type of glue has its own unique properties and mixing them together could result in an ineffective bond or even damage to the fabric.
The drying time for glue when bonding carbon fiber fabric can vary depending on the type of adhesive used and the environmental conditions. It is important to follow the manufacturer's instructions for the specific glue being used, and to allow enough time for the bond to fully cure before handling or putting stress on the fabric.
