Polymer fibers and filaments are used in several applications: what is the most important application commercially?Technically, what is the difference between a fiber and a filament?Among the synthetic fiber materials, which are the most important?
NoIf the manifold was machined correctly, you don't even need gaskets, but that is asking a lotDrag racing engines don't use them Go buy the correct gaskets, or do the same job twice times.
No ,Aluminum melting temperature is low and may result sparks in the exhaust.This section has high temperature fiber gasket that can accept over 1800 degree temperature .These materials known as high resist to the heat which is combination of the ceramic fibers ,metal powder and graphite.
it shallit may not last long though, and a couple layers of foil isn't a very thick gasket i have used sheet aluminum such as roof flashing, house siding and even beer cans as gaskets on tractorsthey do workyou might do better, if you use your foil, to also use the high heat perma-tex (red) silicone toocoat both side with that, then snug up the bolts and walk away for at least 24 hours, 48 is betterthat stuff really holds tight for a long time.
Making an exhaust gasket from layers of aluminum can work but making it from copper flashing would likely work betterI worked in the aerospace industry and actually made gaskets for some applications out of GoldI wish I had gold sheet available to make exhaust gaskets for my daily driver, the exhaust would not leak and the gasket would never fail, but would cost several times what my truck is worth (and even what it cost new 30 years ago)
You will find that a lot of these terms are used interchangably, but in my polymers and composites course, we defined terms as follows: A fiber is the smallest workable component of the polymer (theoretically I guess this could go down to a single polymer chain) A filament is one step upIt is many fibers together to form a single string It is not wovenA yarn is several filaments woven into a small rope I'd say two of the most important synthetic fibers are Nylon and PTFE (Teflon), These seem to have endless industrial applicationsI'm sure to police officers Kevlar would make the list.
