Hello Paul,
Recently I became a share holder in a very interesting Composite
company. This company has the Australian licence for a prepreg
material called Thermotex which is a Polypropylene with E-Glass.
This product is heat activated from 180c to 230c to cure in an oven.
I found this product very interesting as its durability is outstanding.
It is used in Rally car as the under body protection. My research has
led me to the Fokker F50 which used this material in it propellers.
On talking to the company that maintained the F50 through out Western
Australia I was told that they had new blades in store for replacement
and they where never used as they never had the need to replace them.
These plane operated out of all the country strip which mostly in the
early years where gravel and rough. Does any one have more info to the
use of this material in the aero industry. We are making pressure
vessel with this material. This may work with Butches propeller as
production would be quick as you lay the fabric in and put it in the
oven. We have two ovens that are the size of a pantec trailer and we
are working on a larger one for big projects.
