TCR Composites Towpreg Winding Demo
HTML-код
- Опубликовано: 5 окт 2024
- This video demonstrates the ease and cleanliness of using TCR Composites' towpreg in the filament winding process. Also included is the application of stretch tape (used for compaction) as the outer layer, prior to curing in an oven.
*Note: the winding machine process has been slowed for the making of this video.
If someone else have the same doubt about it:
*It's an empty mould, just an giant aluminum can, and it's meant to be left inside, the aluminum by itselft would break, but the CF is holding it tight so when pressurized, it's like if the inside and outside pressure are equalized. But yes, there's also two other types of moulds, one is made of rubber(with structural steel wiring to retain desired the form) and it's inflated, and the other is a meltable polymer, or even soluble polymer, one is pulled from inside when withered, the other is just melted away during the curing proccess or dissolved by a solvent that doesn't cause harm to the CF.*
Thank you 👍
Allah korusun iyi insan! I broke my head thinking how they pull out the part from the mold...
Absolutely gourgeous! Well done sir!
I'm a winding machine operator, from my experience working with a similar machine a cylinders shown on this video could take anywhere from 15-45 mins depending on pressure capacity. A higher pressure will increase the amount of fiber used and winding process.
how to removal fixture can ou help me
@@SimpleLatchMechanism It´s not removable
@@RBAERO I assume there is no mandrel inside the tank, which means that the liner is also playing the role of a mandrel. Any thoughts if there is a risk of liner buckling due to the applied tension load of winding tapes, which "I assume" will generate a compressive load on the metallic thin liner?
Tecnicamente perfetto. complimenti
2:10 Helical Layer
4:12 Helical Transition
4:50 Hoop Layer
Helical & hoop tapes will generate a compressive load on the liner during the winding. Any thoughts on how to check if there is a risk of buckling of the liner? It sounds like the liner in this case plays the role of a mandrel as well. Thanks.
wonderful machine,i like too much.thank a lot to maker.
Good video bro.. 👍❤
How this winding machine cost and what is the model name of it?
if i tape my air freshener spray can will it more powerful? for DIY PCP Cylinder ?
Amazing illustration of pressure vessel manufacturing. Did you get to design the liner regarding any potential buckling failure? How much is the applied load on the liner due to winding tape? Thanks very much.
What's the difference between helical,hoop and polar winding... I thought helical and hoop are one and same
hello how is this machine programmed like cad cam
just wonder, how you take the aluminum mold out after the winding is done?
Hasan Kazani, often the aluminum mold is hollow and is left inside but if a pure carbon fiber vessel is desired a soluble mandrel is used then washed out after curing the fiber. Advanced Ceramics Manufacturing in Tucson, Az. makes water soluble mandrels in just about any configuration. They are a Native American owned company owned by the Tohono O Odam Nation.
The aluminum is meant to be the interior liner. I work at Steelhead Composites in Golden and that's the most common product we make. We have also done linerless vessels which the initial liner is water soluble like Tony said. There are also steel liners and plastic liners, both of which stay inside as well.

Sir please help me how to create join path, vessel to Hoop and Hoop to vessel ?
If Titan was made same way, barely no-one would know about Titan..
How to extract or unwind this towpreg to get the tape like prepreg fibers again?
please reply
eu vir legal muito bom diferente fazer hum hum certo bem!!!!
In which software do you do CAM programming or gcode programming? can you help me?
Sangan baik !
You should really show it at full speed to show what it could do in the end, now everyone think it cant be faster.
How the heck do you get it off?
either its an integral liner or they should be parting at cylindrical region...
I was thinking the same thing!
I meant the thing it is spun onto
Iama Bellend the spun remains inside according to me, but seems aluminum an very lightweigth. It serves tp krep the shape
MIkeflower It would be a disposable mandrill.
Some chemicals corrode polymer and that is why we dont use carbon fibre for space craft fuel tanks, if this is intended for similar chemicals or cryogenics than having an aluminium liner would protect the carbon fibre while the carbon fibre is the structure.
Or, the carbon fibre can be cut on one end to remove the mandrill and than a specifically made end cap can be fitted.
How is the adhesive that binds the layers together applied? At what point in the winding process is it applied? Is the carbon fiber pre-impregnated with the appropriate resin before winding or is the cylinder wrapped and then the binding agent is added afterward?
I've wondered if the carbon fiber is actually bonded to the surface of the mandrel or is it just wrapped around the mandrel with no bonding between the mandrel and the carbon fiber wrap?
it is pre-impregnated
I assume there is no mandrel inside the tank, which means that the liner is also playing the role of a mandrel. Any thoughts if there is a risk of liner buckling due to the applied tension load of winding tapes, which "I assume" will generate a compressive load on the metallic thin liner?
so bassicaly is wraping shape not winding.
How much pressure can cylinder take that?
looks similar to 300 bar cylinders for diving or anything else
How long does it take to wind a vessel like this, approximately?
Depends on the size and intended pressure of the vessel. Where I work we make as small as 0.5 liter, 3500 psi vessels which we can wind in like 10 minutes, or larger ones like 25 gallon vessels that can take a couple of hours and can do 3 at a time.
How to insert the resin?
The material being layed up is "Pre-empregnated" carbon fiber which means that the material has an epoxy resin mixture with an additive that kicks at a higher temperature thus requiring an auto-clave to kick and cure the part.
Kool video but music dud for me
What is it?
very cool
hi
i'm mechanical engineering student. We use CadWind V9.Our problem tansion and winding angle. Which angle do you use on winding ?
Mertcan Akpınar Hi there, i also use CadWind . As for the winding pattern, tension and winding angle, would u like to communicate with me ?
Mertcan Akpınar contect me for any problem

@@mishal531 Hi! I'm looking for a cheap manufacturing process to make 10 meters cubed tanks that can handle water heated to 1000c AND remain liquid, continuously for 25 years. Can you recommend something?
@@l0I0I0I0 water cannot remain liquid at 1000 degrees (F or C). At any temperature above 374 C it will be either in the gas phase (at lower pressures) or it will be a supercritical fluid (at higher pressures). Also, there is no epoxy resin system that can maintain strength at 1000 degrees (F or C). Also, most of the physical properties of water do not remain as expected at such high temperatures. Basically, it is not possible to heat water to 1000 degrees and contain it in a vessel (except maybe as a vapor) and even if you did, it probably won't behave the way you expect. I can't even find a reference giving pressures at temperatures that high. I think practically speaking, whatever application you have in mind is not going to work out the way you think it will.
@@mckenziekeith7434 all good points. I've reflected on this over time, the bigger problem I suspect is that in order for water to suck up those massive BTUs requires the actual phase change to take place, meaning for water to change from liquid to gas. No change no btu jump. Even if you get the phase change, it would require a large cat to contain the gas, I would also think? I'm yet to verify this but I suspect or rational it to be the case. If no phase change, you miss out on many BTUs at the phase change.
There are high temp high pressure epoxies but they are exceedingly expensive but again more importantly after watching the titanic sub implode, I have questions as to how well it would last over time. I suspect stainless steel would be a better choice.
but why do they wrap those cylinders?
you mean the carbon fiber winding !? if so, its for increasing the pressure capability. its a high strength fiber. if you are asking about the last shown tape wrap, its for compaction during curing process (where you can expect volatiles causing distortion ). hope it clears.
Prasan Veni thanx for the useful information.
Yep, for increasing the capability. An aluminum liner by itself won't hold nearly as much pressure as a carbon-wrapped vessel. Carbon wrapped vessels are a lightweight alternative to steel vessels.
to deal with hoop stress for one i guess
