Carbon Fiber Pipe Wrap
Carbon Fiber can be used to wrap the outside or the inside of pipelines as a way to reinforce and strengthen them. Carbon Fiber is lightweight yet extremely strong. It can be field-installed on pipelines that are clean and non-pressurized.
Repairs to pipelines can be extremely expensive if they need to be dug out of the ground, cut out, and replaced with new sections. This is time-consuming work requiring long shutdowns. Composites repairs can be accomplished by professionals that can access the work area and have a line that is non-pressurized and clean.
These carbon fiber reinforcements help to restore structural integrity that has been lost through age, damage, or other new design requirements. There are many advantages to repairing existing pipelines and other structures rather than replacement.
Interior repair from ABC 10 News in California demonstrates an interior pipeline repair:
An external pipeline repair is shown here in an instructional video. I do have a few concerns about the use of all of the unreinforced resin that is used to cover the carbon fiber wrap. I am not sure what the purpose there is, other than maybe to protect the carbon fiber from future damage.
Repair of a Crack in Fiberglass
Cracked fiberglass panels should be repaired before the crack worsens. A crack can continue to spread and also cause leaks through the fiberglass panel. Gelcoat is intended to be a protective barrier to keep moisture from the underlying surface.
Cracks also are ugly. They detract from the good looks of a fiberglass panel.
Fortunately these can be repaired. A short demonstration of the basics from BestBathUSA on Youtube.
The actual repair is more involved, but it is possible to do it yourself. The correct tools and materials are required, but are widely available.
Preventing Rotten Balsa Wood Core
Balsa wood is a common construction material used in the manufacturing of fiberglass boats. Used as a core material, balsa wood is placed between two layers of fiberglass to add strength and rigidity to structures that require it, usually the deck, many times the hull, and sometimes the other areas that require strength.
Using this wood in a marine environment where the boats are constantly exposed to water is dangerous because of the ability for the balsa wood to rot. Once water enters the cored areas of boats using balsa wood, it is a complicated repair job. The balsa wood is between two layers of fiberglass, and to remove and replace it requires removing a layer of fiberglass. This usually involves grinding and sawing as seen here:
As you can see, there is a lot of dust created from removing the fiberglass to get to the rotten balsa. The balsa must then be replaced before the removed fiberglass layer is restored. Care must be taken to ensure that this is completed correctly in order to maintain structural integrity of the area that is being repaired.
To prevent balsa rot in the first place, care must be taken when doing activities that have the potential to expose it to water. Adding fittings and features to structures that contain balsa wood require careful craftsmanship to prevent water infiltration.
Installing fixtures and fittings through balsa wood is possible, but careful work upfront will be very valuable in the long run. There are several ways to do this, one of them is here:
This method of making holes through your balsa wood-cored structure will provide a wall of epoxy resin around the hole and keep the balsa wood back away from any water that may pass through the hole. Good marine-grade sealants applied to the hardware will add another layer of protection.
Aqua Stik Epoxy Repair
Browsing Youtube, I found an interesting video on a repair Epoxy material by the name of Aqua Stick. I am not sure how it is available, but I am sure that you can search it on the internet.
It looks to be very user friendly, and has some very interesting potential applications in the arena of adhesive application and repair for underwater environments. No metering/measurement of the two parts is required, as they only require a kneading action to mix the two doughy components to uniform color.
Subcontracting Boat Repair
Repairs to boats can be difficult to perform yourself. There are many considerations that must be made when performing fiberglass repair on boat hulls and decks. Structural integrity must be returned to the laminate to prevent failure of the repair. Boats must also retain their neutral buoyancy, so that the repaired side must weigh the same as the original side of the boat.
Cosmetics are also important. The surface must be smooth and color matched. This can present several difficulties as gelcoat and paint fade under the UV sunlight. Custom matching must take place.
The materials and practices used to perform repairs may also be detrimental to health and safety, unless proper precautions are made. Protecting your eyes, ears, and skin is important and easily accomplished. Many of the materials have health side effects if used improperly. Excessive exposures are rare, but can prove deadly.
Good practice and training is the best solution to a good repair. That is why it is important to consider hiring an experienced and talented professional to perform any repairs on your treasured boat. Whether it is a powerboat, yacht, sailboat, or ship, qualified and experienced professionals can perform repairs easier, quicker, and cheaper than most novice people.
These experienced professionals can be found via word of mouth, yellow pages, or Internet search. One of the best ways to search is with a dedicated directory, such as www.MarineLookup.com This directory matches local service providers with potential local customers. It is free to search, and a great marketing tool for these talented professionals.
