Tensile Strength of a Neoprene coated flexible connector

Tensile Strength of a Neoprene coated flexible connector

Tensile Strength of a Neoprene coated flexible connector

(OP)
Hello to everyone,

I hope this is the right forum to ask this question.
I have to buy a flexible connector (neoprene-coated fiberglass fabric). I was given the specification of tensile strength in pressure units [kPa] but providers give this strength in force units [N].
I believe it is because I am working with an old standard and I don't get any way to make an equivalence between these values.
Has anyone solved a similar problem?

Thanks in advance.

RE: Tensile Strength of a Neoprene coated flexible connector

Psi are the units given for the tensile strength of a material of unspecified geometry. Lbs. force are the units used for tensile strength of a part of specified geometry. For example, steel has a tensile strength of X psi. 1/2" steel wire rope has a tensile strength of X pounds force. And sometimes people are just careless about units.

I know, but the providers do not specify the geometry. They give the test result according to the given standard (for example Can2-4.2-M77 Method 9.2) and if I use the geometry I have with the specified Strength (in psi) the resulting Strength in pounds is at least an order of magnitude lower that the providers' values. That tells me that this conversion is not suitable.

That test method should call out the geometry of the sample that was used, you can then make your conversion using the test geometry.

I also tried that but since we are talking about fabrics, the cross section changes drastically with small loads and the convertion cannot be made that easely.
I contacted the providers asking this but none replies.
This is the first time I have to work with this so i am a bit lost.

Tensile strength of fabrics is usually given as lbs. per inch of width.
