Polymer with high Coefficient of Friction to Carbon Fiber

AI Thread Summary
A clamp is being designed to secure a hollow carbon fiber tube with a diameter of 2.5 inches, supporting a 15-20lb load at angles between 20-70 degrees. The goal is to find a polymer that can be over-molded or sprayed onto the clamp, offering a high coefficient of friction to prevent slipping without damaging the carbon fiber. The polymer must be durable, resistant to shearing, and suitable for daily use in temperatures ranging from -20 to 120 degrees Fahrenheit. Suggestions include vulcanized rubber or silicone rubber as potential materials. The discussion seeks practical insights on suitable polymers for this application.

Hey all,

I'm trying to design a clamp that has to hold onto a hollow carbon fiber tube, approximately 2.5 inches in diameter. The clamp will be bearing a 15-20lb load. The carbon fiber will be at angles from 20-70 degrees from a vertical axis.

I'm curious if there is a polymer that can be over-molded or sprayed onto the clamp, and have a high coefficient of friction with the carbon fiber, thus minimizing slip. The clamp must not damage the carbon fiber tube. The polymer cannot be easily sheared off and must withstand multiple uses. The environment of use is day to day. If the polymer has a temperature tolerance between -20 to 120 degrees F, that would be fantastic.

Any and all insight would be much appreciated.

Thanks!

Mike

Thread 'How could I make it so ferrofluid drops do not coalesce?'

Hello! I've been brainstorming on how to prevent a lot of ferrofluid droplets that are in the same container. This is for an art idea that I have (I absolutely love it when science and art come together) where I want it to look like a murmuration of starlings. Here's a link of what they look like: How could I make this happen? The only way I can think of to achieve the desired effect is to have varying droplet sizes of ferrofluid suspended in a clear viscous liquid. Im hoping for the...

Thread 'How do you fabricate microfluidic chips in your lab?'

Hello everyone! I am curious to learn how laboratories handle in-house chip manufacturing using soft lithography for microfluidics research. In the lab where I worked, only the mask for lithography was made by an external company, whereas the mold and chip fabrication were carried out by us. The process of making PDMS chips required around 30 min–1 h of manual work between prepolymer casting, punching/cutting, and plasma bonding. However, the total time required to make them was around 4...
