Sandwich Core Materials

Click here to see these products & more on Fibreglast.com: goo.gl/iEbLRc
Sandwich Core Materials are lightweight, structural layers that are embedded between laminate layers in order to build bulk and strength for a part-without adding significant weight. By employing sandwich core materials in your part or mold, you can achieve much higher flexural strength and flexural modulus than using skin laminates alone.
Want to learn more about Sandwich Core? Visit the Learning Center and read our white paper, Guidelines for Sandwich Core Materials.
Sandwich Core materials from FibreGlast.com include:
Nomex® Honeycomb-Offers the very best strength-for-weight ratio in this category; flexible, fire retardant, and delivers good impact resistance.
End Grain Balsa-Conforms to practically any simple curve and most gradual curves.
Foam-Includes sheets of vinyl and polyisocyanurate, as well as mix-and-pour foam; all are closed cell and resist water, gas, and oil.
All the Sandwich Core materials in this category are compatible with epoxy, vinyl ester, and polyester resins, and can be used for most lay-up techniques, including vacuum bagging and infusion.

Sandwich Core Materials: Bacon Lettuce Tomato

[@fibreglast]

Not quite what we had in mind, but I agree those are key elements to any sandwich!

[@steveturansky9031]

Actually, the bread slice would make a better core. A slice of lunchmeat would make a great outer skin as would a slice of lettuce. Mustard and mayo then would be the 2 part epoxy. So obviously, the typical lunchtime composite sandwich has been put together wrong since it's inception.

i eat fibreglass because i'm just built different

[@henry2008kim]

Indeed very helpful! How well does the Nomex honeycomb resist compression? Would balsa wood be better in such applications..?

[@froggy0423]

What is the preferred core material for a boat hull? Honeycomb vs. foam. Which is most impact resistant amongst other qualities?

[@fibreglast]

Marcos, you would need to consult an engineer for that question.

Is carbon fiber ever used as an actual honeycomb material? If not why? Tnx you‼️

Sir if i use pvc foam board to apply a fiber glass it is ok. It not be melted the PVC foam board sir

Very helpful. Thank you!

I have attempted a resin infusion using 1.5" thick closed cell foam core. I wrapped the core after machining with carbon. The mold side is always getting large dry spots even though on bag side I can see the peel ply has wet out fully using the green infusion media. Can you tell me what went wrong? no vacuum leaks, im using infusion epoxy, and it took about an hour to wet out completely. Any reason the mold side (underside) of the fabric wouldnt be wet out?

[@fibreglast]

Hello, that problem could be caused by a range of different issues depending on how you have your resin infusion process laid out. If you could give us a call at 800-821-3283, a member of our sales team will gladly discuss your set-up with you and figure out the best way to resolve the issues.

@@fibreglast Thanks, just gave customer service a call and they helped clear some doubts.

@@Redblood797 that's great! Good luck with your next infusion set up!

Nice information do you have type of honeycomb material for core material of rotor blades. Thank you,

[@fibreglast]

You can email us at [e-mail] if you are looking for a specific coated honeycomb, but the honeycomb shown is used in the aerospace industry.

[@malcolmgreen2811]

I have seen a very efficient process that compresses bamboo wood fibres into things like very tough floor tiles. Could this process be used for making wood composite similar to balsa? Also, we have had good results using bamboo fibres compressed into thin sheeting and laminated similar to layers of glass fibre using standard resins. Could this be an alternative to glass fibre matting?

[@Meleeman011]

how about cardboard?

To me boats build with balsa core are a deal breaker and I would not buy a boat with balsa core in it. I really don't understand how anybody would think that it is a good idea to strengthen your boat with a wooden sponge. Yes it is strong for it's weight but any boat will develop leaks at some point in it's live some no matter of how careful you build it. Having balsa in there that just soaks up the water with no end insight would be just a nightmare. I know there are whole boats build out of balsa core. I would never touch one. But there ar many strong believers in balsa core. Would like to hear from them .

Do u sell that oven ( autoclave) in the background? Where can I get one? Brand and model number?

[@fibreglast]

Unfortunately we do not sell the oven in the background. It has been around here for a long time so I wouldn't be able to tell you where it was purchased. it is a Quincy Lab 30 GC oven.

these dont look too good to eat. are you sure these are made fore use in sandwiches?
