I think some people are getting a little confused in here.
Fabrics measured in gsm grams square meter. Within that fabric you may have something commonly known as ripstop. This is just a thicker thread woven amongst thinner threads.
Now the "new material" which doesnt belong to ocean rodea at all but they are useing it on theyre kites is according to the salesman half the weight 75gsm as dacron (allegedly 150gsm) but just as strong... Or stronger?
Now the RIP TEST was always marketed on the actual canopy of kites not the structual parts (leading edge and struts) and it was basically just a little leaflet book to show you d2 (2 thicker lines woven in) was harder to rip then d1
Heres where some of you seem to be getting confused. 75gsm is obscenely heavy for a canopy fabric but allegedly light for a kite frame. Canopys particularly in foils are more around 20gsm
And with some ultralight gliders apparently being reported by repairers to be somewhat akin to opening a chip packet after a few hundred uv hours
www.flyozone.com/paragliders/products/gliders/ultralite-4 you can read the stats below were talking 27gsm for bottom skin and what looks to be 20 for top. On a 19 square meter wing keep in mind 2 skins and all the ribs!! So close to 40square meters cloth coming in at 2kgs!!!
Same manufacturer so simular build methods 13 square meter kite in what they consider ultra light is simular weight 2kgs
ozonekites.com/products/water-kites/hyperlink-v2/Obviously your going to use a more durable fabric for kiteing due to the added wear and tear that can occur.
Point is material selection is a choice. Weave had lighter stronger heavier weaker whatever characteristic you want available for years and years. Theres always a positive and a negative with every choice. One heavier denier line 2, 3, 2.5, 4. Then youve got your coating options before its woven and after even different weaveing methods and patterns can be achieved to give fabric strengths in different directions bit like torsion on your boards.
Saying some hinky dink kite brand invented or own a material created by whats usually an enourmous business that then sells a few reems to a kite brand or might even give them a contractual agreement to only supply them and no other brand a particular cloth doesnt make it THERE'S.
Id say theres a good chance the canadian boffins who worked on the aluuulluuu who happen to also kite will be closely entwine with ocean rodea tho given theyre a local company to them.
Ill be interested to hear who is actually making the fabric and what country its being made in.
Anyways a quick google showed me a few years old paragraph on the cabrinha contras build with some fabric weights to give you an idea. A
Cabrinha kites are designed and built on a Skeletal Frame foundation. We start by placing the most durable, 160 gsm Dacron material into a framework that locks in the intended shape. We then create the canopy shape and profiles with a light weight yet highly durable 53 gsm polyester woven material. We build on the durability of the canopy material with a second layer of 53 gsm two-ply material over the high stress strut sections. Next, we layer into the perimeter a 75 gsm, double ripstop reinforcement material to combat the extreme loads that are placed on the trailing edge and wing tip areas of the kite."
Anyways i think i can see my tail now and this has been fun going in circles and all
Tldr
People dont do tear tests on dacron they did them on canopy material i doubt anyones tearing a sheet of dacron. So his little tear test was a bit stupid tbh
Dont get kite frame fabric and kite canopy fabric confused.
