Could anybody tell me what material will give the best tensile strength to weight ratio? I figure it's between steel cable and the nylon type stuff used in some dog leashes, but I'm not sure which.

bmyers said:Currently, this IS the strongest, most versatile synthetic fiber that I am aware of. If anyone knows of another, please let me know, as I am always looking for new materials to experiment with.
The Magellan site has a page with the mechanical properties.Facial said:I find this interesting. Are there any specs on the mechanical properties of this polymer?
1. A rigid rod polymer in which at least 50% of the recurring groups correspond to the formula: ##STR4##
2. The rigid rod polymer according to claim 1, wherein at least 50% of the recurring groups are composed of pyridobisimidazole-2,6-diyl(2,5-dihydroxy-p-phenylene), and in the remaining groups (a) the 2,5-dihydroxy-p-phenylene is replaced by an arylene which may be substituted or not, (b) the pyridobisimidazole is replaced by at least one of benzobisimidazole, benzobisthiazole, benzobisoxazole, pyridobisthiazole, and pyridobisoxazole, or (c) both.
Steel is actually pretty mediocre in that department. My guess is that Nylon's is several times that of steel (I tried to google it, but all I got was this thread! ) . There are lots of relatively mundane elements and alloys - even basic aluminum - that have much, much better strength to weight ratios than steel. And then there's the more exotic, like some of the things others mentioned. But as asked - what is the purpose of the question? Application makes a big difference.BasketDaN said:Could anybody tell me what material will give the best tensile strength to weight ratio?

Tensile strength to weight ratio is a measure of a material's ability to withstand tensile stress (pulling force) relative to its weight.
Tensile strength to weight ratio is important because it allows for the comparison of different materials in terms of their strength and weight. This is useful in engineering and design, where lighter materials with high tensile strength are desirable for applications such as aircraft, bridges, and sports equipment.
The material with the best tensile strength to weight ratio is currently carbon nanotubes. These microscopic cylinders of carbon have incredibly high tensile strength and are extremely lightweight, making them ideal for use in various industries.
Tensile strength to weight ratio is calculated by dividing the tensile strength of a material (in units of force per unit area) by its density (in units of mass per unit volume). The resulting value is a measure of the material's strength relative to its weight.
Yes, the tensile strength to weight ratio of a material can be improved through various methods such as alloying, heat treatment, and processing techniques. Engineers and scientists are constantly researching and developing new materials with higher tensile strength to weight ratios for various applications.
