What is the risk with grinding carbon fibre material & inhaling the fibre/particles? Not that I do grind them, but am using the material more & wondering if I need to adjust them, what are the risks?

 

They are s...ts of things to grind.

See these threads:
Grinding orthotics made from carbon graphite composites
Carbon fibre as an orthotic material
Carbon fibre as a foot orthotic material

 

Hey Mahone, if you want to be listened to less of the name calling would probably be a good idea. I posted the initial question & appreciate Craig's views as well as others.

 

Zac:

It would be best for your health, your coworkers' health, and patients' health to not grind a carbon fiber orthosis without first donning a good quality respirator and having a very good vacuum unit that will ensure that no microscopic carbon particles become airborne in your workplace. You may want to check your national material and industrial safety codes to make certain that carbon composite material grinding is even legal in your workplace. I wouldn't grind the stuff in an office setting...it simply isn't worth the risk, in my opinion.

 

The obvious reason is because this website is asserted to certain people. We had this discussion couple years ago..if someone posts something in contradictions with your personal interest then the message gets deleted...

 

He is talking about Carbon Fiber orthotics...your post is technically parallel with the reality

 

Your post is at odds with reality. Why don't you say what you mean and contribute something worthwhile, instead of commenting on other people's posts?:butcher:

 

Having made many pure carbon fibre orthotics in the past (as well as composites) I would not grind them without protection, the risk of fibres is not worth it.

 

Aloha,

Thanks Kevin your comments are correct and show concern for our staff and patients.

All orthotic work should be done in a area suitable for proper vapor, fiber, and particle filtration and ventilation.

We should not discount composites because of this. They are light weight and have a very high modulus of elasticity "spring" as well as having superior puncture and fire resistance properties over "non reinforced" molded plastics and blown foams.

We should take this extra effort to start building with advanced composite orthotic and shoe systems. It may be worth the extra efforts.

Mahalo,
Steve
