Den store kunststof koncern 3M (de laver alt fra tape til flueliner) har lanceret et nyt kulfibermateriale  baseret på nano-teknologi der ifølge 3M er både lettere og stærkere end alt hvad de tidligere har udviklet.

Orvis er særdeles gode kunder hos 3M. Orvis får nemlig alle deres flueliner produceret hos Scientific Anglers som er en underafdeling af 3M koncernen. Af den grund var Orvis selvfølgelig blandt de første der fik tilbudt det nyudviklede stangmateriale. Tilbudet kom samtidig med at Orvis netop var blevet færdig med deres egen patenterede thermoplastic system som idag bruges i bl. a. Helios I stængerne. Orvis testede de to materialer mod hinanden grundigt, og endte op med at sige nej tak til 3M.

Efterfølgende har andre stangfabrikanter taget den nye 3M teknologi til sig. Det bliver spændende at følge.

Læs her hvad Tom Rosenbauer, direktør for Orvis’s stangdivision, siger om deres test og beslutning:

Orvis experience with the “new” nano materials

There has been a lot of hype in the press lately about the new rods produced from a nano-composite developed by 3M.  Our rod designers were offered this material two years ago and, on paper, it looks like a great raw material for making fly rods with standard epoxy resins.  There is no doubt that the 3M Matrix Resin 3831 will improve the strength of rods made with these conventional materials, but in our tests it came up short (as compared to our high-temperature-cure thermoplastic resins) in two critical areas:

 Impact strength.   When comparing our thermoplastic system with the 3M resin system our Helios technology showed better impact strength.  Sooner or later, all rods will be hit by a Clouser Minnow, impacted with a split shot, or banged against the side of a boat.  Our patent pending Helios technology, also used in Hydros rods, offers 15% better impact strength according to our tests.

Fiber translation.  To make a lively and responsive rod, it’s very important that the resin system allows the energy developed by the casting stroke to transfer from the carbon fibers of the rod into the fly line.  The more flexible and responsive the resin system, the better the fiber translation.  Our tests showed that our patented Helios thermoplastic system gets 10% better fiber translation, meaning a 10% greater transfer of energy.

 The composite system which we have patent pending for fly rods has been tested for 7 years by Boeing and the military.  If the 3M fiber is so good, why is it not used in Apache helicopter blades, where strength, light weight, and durability are literally a matter of life or death?

 We should stress that we have not cast any of the rods by Hardy, Loomis, or St. Croix.  Nor has anyone else outside of their field testers and staff.  We can only report the results of our tests two years ago with the 3M material.  Once we get a chance to fully examine these rods we’ll report on further findings.
