Hello,
I'm attemping to use a viscoelastic foam as an energy absorber. Can someone help me to find a viscoelastic foam with high strength?
Foam in breads. Gluten is known to make stronger viscoelastic foams.
I need some more suggestion to compare and make a correct decision, help me please. Note that strength is one of the most important parameter in this study.
Hi Mahsa, look for the formulations used to make foams for fire extinguishing. These foams are very persistent and viscoelastic. Look into patents, this is where I found the information when I was looking for how to prepare these foams. I don't remember the formulation exactly but a surfactant such as sodium lauryl ether sulfate, or sodium dodecyl sulfate is required (they have good foaming power). A polymer such as a polyacrylamide is also mandatory.
The right answer depends on the constraints. What is the application? Is the foam permanently inside a shock-absorbing garment (for example) or to be sprayed, as for firefighting (already mentioned) or some other need. Giving more details will get you a better answer.
@ Dr. Briceno: Thanks a lot.
@Dr. Parker : I want to simulate a crash box and I need a viscoelastic foam as a filler to improve crashworthiness. So your answer is yes, the foam is permanently inside a thin-walled crash box. Thanks for your help, I hope to recieve your future help and guide.
