NB Remember FibreForm is stronger one direction than it is in the other. Both ways are tested.
The diagram below shows the stretch of the paper until it tears. This is the extension of each paper before tearing, these readings were very interesting, we can see from the results that FibreForm stretched nearly twice as far as cartridge paper on its weak direction and 3 times further on its strong direction. It is very interesting that the strong direction stretched much further than its weaker side. Amazingly the strong side stretched over 12mm before it teared, this is quite a distance for paper to stretch. Out of the non FibreForm papers the Cartridge paper performed the best, extending to 4.5mm which again is a substantial amount.
Tensile strength is the maximum stress that a material can withstand while being stretched or pulled before breaking. This is different to how much weight a material can hold. This reading is important as the stress which FibreForm can withstand will be very important if it is being thrown from a plane or hitting the ground. From the diagram below we can see that again Cartridge paper performed the best out of the non FibreForm materials. Both directions of FibreForm performed the best with FibreForm strong direction measuring three times stronger than non FibreForm paper and nearly a third times stronger than FibreForm weak direction.
Maximum load is measured in Newtons. 1 Newton is the equivalent of 102g in weight. Mountboard performed very well in this test with 87 newtons and 8874g and was stronger than FibreForm weak direction. Cartridge paper did not perform well and performed the worst out of all samples. FibreForm strong direction went above and beyond any other material racking up 146 newtons which is 14892g which is nearly twice as strong as any other materials.
In a nutshell FibreForm is clearly far stronger and stretchier then any other paper tested.
