Lasikuituiset lehtijouset

[Revolver]

http://www.petrisimolin.com/ThePalst...TOPIC_ID=34497

Yllä olevassa topicissa oli keskustelua lasikuituisista lehtijousista ja miten ne mahtaa toimia märissä olo suhteissa. Ottaen huomioon että lasikuitu imee itseensä vettä ja menettää taipuisat ominaisuutensa sillon. Tästä kiinnostuneena otin yhteyttä Teraflex Suspensions (http://www.teraflx.com/) nimiseen firmaan, jotka ainakin näitä jousia myyvät.
Sain heiltä äsken sähköpostilla vastauksen, aika vikkelästi vastasivat pisteet siitä. Tässä siis kysymykseni ja mitä he vastasivat. Jos joltain tuo lontoon murre ei taivu niin voin tässä myöhemmin illalla kääntää nuo jutut, jos joku muu sitä ei ole tehnyt. Nyt nimittäin olen menossa uazin kimppuun

Kysymykseni:

Hello,

I recently noticed your new Fiberflex suspension system. I must admit that
the thought of fiberglass springs is quite revolutionary. Probably you will
get very good axle articulation with the springs, but one thing came to
mind.
How does the spring work in wet conditions? If the protective layer on top
of the fiber glass is shredded away by rocks and the springs are soaked in
muddy water. Ordinary fiberglass sucks water like a sponge if the top coat
is peeled away. Then the fiber glass looses all its flexing ability and
snaps.
What precausions have you made to the springs so that this would not happen?

Yours sincerely,

Good questions

These springs are manufactured by high pressure injection which has some
major benefits. One benefit is that they become very dense with no cavity or
gas pockets that could allow moisture to be absorbed. Another benefit is
that the direction of flow in the injection mold tends to align the glass
fibers giving the spring a higher strength.
The springs do have good articulation but not really more than a good steel
leaf spring. They are really better than steel in these areas;
Durability-These springs can be pushed much farther than steel. The yield or
stress point of Steel is not nearly as good as the glass. Our destructive
testing showed us that the spring when mounted on a YJ could move up 11
inches and be left for hours in that stressed position with no damage. The
spring could be pulled down 14 inches with the same results. Going further
did cause the spring to begin a breakdown of some fibers but the spring
didn't have a catastrophic failure and it returned to its original shape and
maintained its ride height. This is much better than a steel spring could
do.
Another big advantage to the spring is the control it has with axle wrap.
With the FiberFlex spring 90 percent of the users will not require any
additional hardware to control the axle wrap.
This technology is not new and in fact the OEM manufacturers have used high
pressure injection fiberglass springs for over twenty years.


I hope this helps answer your questions

Että näköjään he ovat tuota ajatelleet. Mutta näköjään suurin hyöty noista jousista tulee painon hallinnassa ja siitä että akseli ei yhtä helposti kierry. Joku rohkea jeeppi mies voisi tuommoiset tilata ja kokeilla
