This is really a waste of time. I worked at eliminator boats we could have laid that boat up in half the time. The guy brushed the gel coat on he should have used a spray gun for consistent thickness. I also noticed they didnt glass stringers in either for rigidity full lenght of hull.
I'm sorry that you feel this is a waste of time but, with respect, I think that you have missed the point. We have used this small hull to demonstrate the principal of infusing large composite structures. Our customers are successfully using this principal to infuse laminates which consume up to 8 tons of resin (boat hulls, turbine blades etc) Hand laminating on this scale is not an attractive proposition! Regarding the lack of stringers- the structure of this hull is irrelevant as it is not a commercial product- however, the final product includes an internal seat/floor moulding which is bonded in place and which provides rigidity. Spray gelcoating would of course be preferable in a 'production' situation. Anyway, thanks for watching!
+Compositeinteg1 does it have to be a composite? Is that the reason you added the gel coat into the mold so there wouldn't be a problem when to other resin was injected to the fiber?
The white gelcoat was added simply to provide a good surface finish to the final moulded hull. The mould is coated with a release agent so this gelcoat (or the injected resin) doesn't bond to (or damage) the green mould surface.
How is the mold made? He wants to make himself a boat, but my mold is the biggest problem. How to do the final product does not stick to the mold. I'm sorry about the bad English and I hope you understand what's the problem.
We use a 'release agent' to protect the mould and to stop the resin and gelcoat from sticking to the mould. In this application we used material from Marbocote (www.marbocote.co.uk/)
The hull laminate is formed with multiple layers of glass fibre reinforcement which are all infused at the same time. I hope this answers your question.
Was any heat used during the curing process? The fill process seemed quick, how long did it actually take? What temperature do you pull the part at? Thanks....
No, in this instance the mould isn't heated. We are using a standard room-temperature curing infusion-grade polyester resin with a gel time of approximately 45 minutes. The actual fill time was about 20 minutes and we de-moulded the part after peak exotherm.
Compositeinteg1 We use a heated mold and usually heat to 150 degrees F. and wait for the part to cool to 120 degrees F. What are your thoughts on too much heat and not enough cool down? We make fiberglass parts for the motor home industry. Many Thanks for your help!
This will entirely depend on the type of resin being used. This demonstration used a standard 'infusion grade' polyester and so heating to this temperature wasn't necessary. A heated mould is useful to accelerate the gelcoat cure and to help post-cure the moulded part but 150F does sound rather high if you are using polyester.
The materials used on top of the glass fibre reinforcement are the various vacuum-bag infusion layers. The blue material is a flow-mesh (to enhance resin flow over the back of the laminate) and this is used over a peel-ply (to aid release and to leave a clean surface on the back of the laminate). The final green layer is the actual vacuum bag film.
Hi, If you don't like the look of this process you would really hate the traditional hand-laminating process! Maybe you're safest staying on the beach!!
Beautiful. Thanks for sharing all the steps to building this boat. Fascinating indeed.
Thanks for the feedback Therese- I'm glad that you enjoyed the video.
Admirável a arte, porém é mais fácil estampar em alumínio, ou outros.Parabéns pelo trabalho.
sorry how about using simple vacuum mould manufacturing sisal composite....epoxy resin is it available
CONGRADULATION GUYS.

Is the green mold plastic?
The green mould is a conventional 'composite' laminate. It's made with vinylester resin and glass fibre. The green surface is the vinylester gel-coat.
+Compositeinteg1 does it have to be a composite? Is that the reason you added the gel coat into the mold so there wouldn't be a problem when to other resin was injected to the fiber?

혹시 한국분들중에 이동영상을 보시는 FRP 고수분들동영상에서 제작자가 FRP섬유를 올릴때 한장만 올리는거 같은데 두께가 두꺼운 섬유를 한장 사용하여서 성형하는 것인가요? 아니면 여러장을 적층하여서 성형하는것인가요??
The hull laminate is formed with multiple layers of glass fibre reinforcement which are all infused at the same time.
I hope this answers your question.
질문에 답변해주셔서 감사합니다!! 그러면 여러장을 적층할시에 섬유 한장 붙이고 수지바르는 식을 반복해서 성형하는 것인가요??
No, all the layers are moulded (infused with resin) at the same time.
What materials are "the peel-ply release film' and 'the vacumm bag' ??
Hi- please feel free to contact us using the details at the end of the video. We'll be happy to help.

還有撕下來的白布及藍布是什麼材質??

這蓋著的膠布.是什麼材質的?
hy where from I can get this machine? thanx
Hi- you can see our contact details at the end of the video. Please feel free to get in touch.
kg?
Approximately 18kg of resin was used in this hull infusion.
Obshy weight of the boat and Width laminate?
I'm not sure that I understand your question but the total weight of the Hull (glass and resin) is approximately 36kg
ОК
I’d hate to do that day in and day out.
