Mate, your hair! Just went back through the older videos and saw what you had years ago. Rockstar.

There is a trick that few people do or know that will make the bond 1000 times stronger, but you got to use some slow cure epoxy. Always hit the part with heat until its as thin as gasoline try and keep it there for a few seconds without it smoking. If to much epoxy dripped off just add more. You don't need to hit it with heat a second time unless you're baking it in the oven. What this does is it turns the epoxy so thin that it fits into all the micro scratches grains and spaces this makes the bond literally more than twice and strong. I used to make kiteboards and a repair over cured epoxy was worthless without heating it up. You can do a test, put some fiberglass and epoxy over glass and let it cure in room temperature leave a little fiberglass off so you can pull on it later. Then do another one and heat it with a heat gun for a few seconds till it turns super thin then let it cure. After they are both cured you will never be able to pull the heated epoxy off the glass. The unheated one will pop off quiet easy depending on the room temperature it was curing in. This makes such a strong bond Im willing to bet it would be stronger even if the part to repair was not sanded.

Hi Leonard, thanks for your feedback. The repair covered the extent of the damage. That canoe's now been back in the water playing water polo once or twice a week for over a year with no sign of weakness from the repair. The purpose of the video was to demonstrate a simple repair that anyone could easily do, not a masterclass. The repair has proved more than adequate and hopefuly encouraged people to have a go themselves.

Used this process to repair a 1/3 scale glider fuselage that had snapped in two places after a heavy landing. The EasyComposites scales are invaluable for correct mix of the EL2 and release film makes life so much easier when applying the wet carbon. Great vids and a great range of products! Thanks!

I have no idea what feathering is. However I have found this video useful. My slalom kayak is made from the same material as the hull in this video. The epoxy layer on some parts of the hull have worn away making it slightly (only very slightly) soft in parts. Could I just apply another epoxy layer or two, or would I need to patch it?

Dry the kyak fully to see if the parts are firm again. If they are still soft, then there has been some structural damage and you would be best patching the repair to replace the strength lost.

i remember using this 2 part epoxy paste that smelled like corn chips and it took 32 hours to cure, and was hand workable. I had a friend come to me with his ct90 Honda, that had the chain bunch up and break the casing away leaving a open gap letting all the oil pore out, and I fixed that with the 32 hour resin and fiber glass and Kevlar sandwiched the Kevlar was the main structure the glass was for fill, as I removed any lose aluminium, lucky the bolt holes where on both side of the break so I did not need to drill bolt holes, it hardened like clay, slowly getting stiffer, I was able to sand it for the aluminium cover to fit and not lose oil, and that bike worked for years, I sold it and never heard if it still works but it was treated like a dirt bike so you never know wish I took picture.

Thx a lot!

Cool! Thanks!

I am planning a major project using your prepreg products, I was first studying the carbon fiber prepreg but since this cures in room temperature I wonder if it would not be feasible to make my entire project in Kevlar instead. Multi-layering Kevlar, without the need of using an oven must be the simplest way. I want to make a complete dakar rally fairing plus fuel tank for my motorcycle. Would you recommend to do it purely in Kevlar? I will also make a bash plate.

There are plenty of room temperature curing resins to choose from so no need to go down the pre-preg route unless you specifically want to. You can use kevlar in that way to provide the impact resistance.

If they are deep you can fill them with a light overcoat of resin - sometimes a cocktail stick can be used to dab resin into the hole. But if shallow and they sand out without exposing the fibres then all is good.

@easycompositestv

Generally you would aim to repair using the same material the kayak was made with. In many cases these kind of kayaks are a Carbon/Kevlar hybrid cloth and hence that is what is used here.

I am currently making a set of bowls of 12 cm diameter by layering up cuttings of 2-2 twill on top a metal bowl turned upside down (this is primarly for practice, but I'll try high temp resin instead of EL-2 in case I want to use it as a piece of dish). At first I PVA-coated the metal bowl and in one go layered up the fabric wet. While cutting and layering, some of the 16 patches (orange peel shaped) frayed and left loose strands of fibre across the wet surface. By the end of the pot life the patches were placed more or less as planned, and I wrapped it all in shrink tape, which was a bit messy on the resin but ok. Put that into the the oven at 120 C. The tape shrinked as desired, but the resin partially hardened as foam underneath the tape. A few hours later I had to pry out and destroy the metal positive to get a release. The next time I'll want to make it better. First, I am thinking of putting a layer peel ply and/or release film underneath the shrink tape. Second, I'll add to the metal positive a polished epoxy surface to apply the PVA onto. I can also think of stretching a layer of release film over the outside of the metal bowl alternatively, if I can do that with no wrinkles. Do you have any further suggestions for me?

@easycompositestv

4 жыл бұрын

Wow, there's a lot to unpack there. I'm not sure where to begin! Firstly, I wouldn't recommend PVA as a release agent for high temperature use, you would be better with Easy-Lease chemical release agent. As for the shrink tape method, I think this is always going to be pretty messy. Given the shape you're trying to make I would suggest getting two metal bowls and using Easy-Lease on the inside of one and the outside of the other. You could then use them as matched tool. If you clamp the two bowls together whilst the resin cured then this could create a decent result and have a smooth finish inside and out.

To cut out a section of the hull and replace it to completely remove the damage is rediculously over the top for that kind of damage. The repair done is perfectly strong enough, and more importantly and the whole point of the video, is within the means of your average guy. To make a near invisible factory style repair would be both expensive, and likely impractical for people to do at home.

Is the epoxy finish uv-resistant (i.e., will it withstand outdoor storage)? I know most epoxies are very susceptible to uv damage, and was wondering if this product incorporates inhibitors?

@easycompositestv

7 жыл бұрын

Hi Jack, the resin we use in this video is our Rapid Repair Resin; this resin specifically focuses on mechanical performance and so is not specifically designed to offer enhanced UV stability however it is part of a newer generation of epoxies which do hold up to UV rays much better than older systems and so for repair use, as used in this video, it would be perfectly fine and still look good and work well for years to come. We do have epoxies which are specifically intended for cosmetic applications where any slight yellowing or discolouration would be a problem, such as our XCR (Xtreme Coating Resin) which could be used as an alternative to the Rapid Repair Resin (used in this video) if you're looking for the very best in UV stability.

Relating to the kayak used in the video, what would be it's typical construction? i.e. what weight fabric would have been used and how many layers?

Yo guys, we have a similar boat in our shed that is sort of bent on the line of the joint between the hulls..., we were wondering if you have any experience on recovering the shape? Can we possibly heat it up and soften it and try to remold it? We would really appreciate thoughts. Kind regards, Alejandro

@easycompositestv

The resins used are generally thermoset resins if it is a composite boat, so heating it up is not generally going to work. You could jig the boat into the right shape then add bracing and more reinforcement to hold it in shape.

So I bought an Impex Currituck Carbon/kevlar and I noticed (webbing cracks) and a chip in the hull (outside) and a break in the fiber pattern inside. In the skeg box area the finish is breaking away as well. Should this be done by pro, how much would it cost?

Could you make a video about how to polish these kind of Kayaks?

@easycompositestv

Well, the correct polishing process would depend on what the actual surface of your kayak is; whether it’s gelcoat or paint, whether it’s epoxy, or polyester and - quite importantly - how thick the coating is. All that said, a relatively fine abrasive paper (400+) and then a polishing compound such as NW1 would be a good starting point in many cases.

This is the only example I've been able to find so far for using release film in hand layup without a vacuum bag. Is there anything special about this film? Could you use regular shrink wrap? In any case, it seems like a good way to get a nice finish on something too large to vacuum bag.

@easycompositestv

3 жыл бұрын

You’ll almost certainly find that shrink wrap will stick to the resin, which is clearly not a good thing. This release film is made from FEP which is totally non-stick to all of the major resin groups. It’s also strong and stretchy, making it ideal for this application. You can also use ETFE release film, that works great too. Both of these films are specialist to the composites industry.

@easycompositestv

8 жыл бұрын

The release film we use is ETFE which is an excellent combination of release properties (practically nothing sticks to it) with strength and stretch meaning it works really well for this type of repair. The problem with clingfilm is that they're not all made from the same material - some will release from epoxy resin and others will stick to it so it would be important to do a test run first. The second issue is that they're much more stretchy and less strong making it harder to get quick as good a finish, however, certainly experiment and you might find you can get results you're happy with.

For the life of me, I can't get this smooth, bubble free, finish with the release film.

I've tried 4 repairs using these steps and have not been able to get the perfect finish yet. Can you guys give any more detailed steps or tips for this part of the process?

@easycompositestv

If you are still struggling with bubbles, very gentle waft a heat gun over the top of the bubble. The resin should thin slightly then the bubble will come to the surface and pop. Once most the big bubbles are gone, then apply the release film working from one side carefully to avoid air inclusion underneath. Even if you do get the odd wrinkle, you can sand it back flat, if necessary recoat, then polish back up to a gloss.

I am now making my very first combat knife sheath by using a blowgun on polyethelene plastic sheet 3mm thick. the finish is amazing.I would love to make a guitar case out of this material and also out of this carbon fibre course weave material used on your canoe, but then it all depends on the price of materials in relation economically to the product. I made a rifle case once by joining two plastic kids school cases and cutting joining and reinforcing them and finished them off with angle aluminium metal beading on edge using rivets screws and fibre glass ribbon tape. glass fibre is a beautiful thing. have any of you ever read captain cooks amazingly descriptive paragraphs in the chapter of his first sighting of surfing in the Polynesian islands or probably Tahiti?. Well read it , it will blow your minds. And so that's where they got the name polyester resin. it was name after Poly the Parrot that belonged to Captain Silver in the Polynesians.
