DIY Paper Yield & Tensile Strengths

Hey there!

I'm about to do some tests with rotating boundary layers and wanted to use rotating sheets of paper (cut into circles) as this would be ideal for my experiments.

I was researching various materials but couldn't find yield and tensile strengths for different types of paper (printer paper, kraft paper, etc.). Is there documentation of the yield and UTS of common papers?

Thank you so much!

Bystander,

I definitely have done my due diligence search-wise, even exact phrase matches like you've provided. Either it returns a paper written on the subject (instead of actual PAPER as the material). I have also looked at several videos but to no avail. I hope I haven't overlooked what I'm searching for due to sleepiness, but I'm sure there's a simple materials sheet but I can't find anything. Thanks for any help!

Edit: I found what I needed FINALLY, I'll post it soon if others are interested.

Please do, and tell us more about your project, if you can.

Well the information has to be out there someplace.
Papers comes in rolls from newsprint to fine paper.
Rolling it up and unrolling for printing would involve some tension, and the machine operators would need to know how much before the papers tears or rips.

From this link:

Strength Properties

Bursting Strength
Bursting strength tells how much pressure paper can tolerate before rupture. It is important for bag paper.
Bursting strength is measured as the maximum hydrostatic pressure required to rupture the sample by constantly increasing the pressure applied through a rubber diaphragm on 1.20 - inch diameter (30.5 mm) sample. The standards procedure is described in TAPPI T 403.

Bursting strength depends on basis weight of paper. To normalized the bursting strength for various paper, bursting strength is reported as

Burst Index = Bursting Strength (kPa)/ Grammage (g/m2) or

Burst Factor = Bursting Strength ( g/cm2)/ Grammage (g/m2) or

Burst Ratio = Bursting Strength ( lb/inch2)/ Basis Weight (lbs/ream)


Typical Bursting Strength Values (Grade) KPa
Coated Paper (130 g/m2) 200-300
Coated Paper (250 g/m2) 300-650
Bond Office/Business Paper (100 g/m2) 250-300
Carbonless Paper (50-60 g/m2) 150-200
Bleached Kraft (60 g/m2) 210-260
Test Liner (186 g/m2)250-475
Not really all you'd want, though.

Many papers have a definite "grain" to them. Will that be a problem in your experiments?
