R Group: Forum Members Posts: 19, Visits: 84	Glad to be here! I have started working with composites just recently and looking to add it to my Industrial Design Portfolio. I have one question to start off with. What is the best material to use as a plug to laminate a simple carbon fibre plate through vacuum infusion? I have tried acrylic and aluminum. However, it never comes out with a clear and clean look. I would appreciate any suggestions. Thank you

R Group: Forum Members Posts: 19, Visits: 84	Thank you, much appreciated! As seen on the photo below I have been getting this white sort of finish. the reflection of the light is pretty clear. However, that the scratches and the "White finish" is ruining the part. What could this be? The resin, the finish of the plug? Once again, any suggestions on how to avoid this and get a great finish would be appreciated it.

Hi Raf If it's a flat carbon sheet that you'd like to produce, then a glass sheet would likely offer the best solution to getting a glossy cosmetic finish. Depending upon the size required, a mirror...

Just be careful about your choice of release agent on Glass. We would recommend a good quality modern chemical release agent such as our EasyLease or similar. Problem being, mould release wax is har...

Thank you for the help, I appreciate it! I have been using 'Partall' PVA, but I am afraid it will ruin the gloss look once applied and laminated. Do you suggest that would be the case? Thanks in...

PVA will definitely ruin the glass finish. It creates its own surface, so you will get virtually the same finish off any flat surface whether it's aluminium or glass or plastic, etc. In fact it would...

Great, thank you! What is the best use for the PVA that I have? I am also planning on making a mold out of a plug made up of Industrial Design clay. What is the best recommended finish for the clay...

Only use PVA when you have a plug with a questionable surface, like a 1k paint or the like where you need to create a barrier.

Thank you, I appreciate it! One more question in the time being. What is a breather cloth used for? Does it just replace the infusion mesh, or is it supposed to be placed on top of it? Also, if any...

rafapiccoli - 5 Years Ago

Breather is used on prepreg parts to get a good airflow in the vacuum bag and therefore even vacuum levels across the part. When used on a wet layup the same fleece is referred to as bleeder. There.....

In terms of the clay, I'm not certain how tough or durable it is, but if it's anything like the consistency of most car body fillers/bondo, then it might be necessary to give it a fairly light...

MarkMK - 5 Years Ago

Thank you, I truly and kindly appreciate it! It all makes sense to me now. I also understand that I am to weigh the amount of Carbon Fibre I chose and from that I can define how much resin to use......

rafapiccoli - 5 Years Ago

For simple wet lay that works fine. You don't need to physically weigh it out if that's a bit awkward, just calculate it from the nominal weight of the cloth and surface area used. eg a 200gsm cloth,...

Its hard to tell in photos but it could be slight marring on the mould surface, a slight witness mark from the release agent? How was the release? did it come off easily? Sometimes on thin sheets, if...

Warren (Staff) - 5 Years Ago

On that attempt, I used just Wax Mold Release and not a chemical release agent. I will now try with a chemical one on a polished glass surface as we discussed earlier and can definitely let you know....

I am back with another question. What is the best way to properly apply Duratec Surface Primer (707-002)? As in sanding, cure time and so on? Thanks in advance Rafael

rafapiccoli - 5 Years Ago

I would follow the manufacturers recommendations. Its not a product I have used personally.

Warren (Staff) - 5 Years Ago

I hope all is well with everyone! I finally managed to produce a usable Mold. Though, now that I reached this stage, what is the next best recommended move to ready the mold? Would I need to wet san...

If the finish is not already high gloss and smooth, then sand it smooth and then polish it to a high gloss then you should have a tool ready to go.

Warren (Staff) - 5 Years Ago

Thanks Warren!

I am currently making a carbon fibre case for my AirPods and I noticed that the best way to laminate the bottom part of the case (Bigger Side) is to make two separate molds and then glue them togethe...
