how do these polymers material behave on a tensile test OR impact test?

You should look up the numbers.  Off the top of my head, I think nylon is used for ropes because it has good tensile strength.

It would depend on which substance you are studying. Every substance does not polymerize at the same temperature.

Its better to get a design engineering guide from one of the plastic raw material suppliers as modifying the melt flow index would change many other properties also. A manufacturer rather than a distributor would probably provide you the information more readily.

I am not sure but I would guess that the polyester will hold up a little better than the paper through all of the movement of the windings. Adding to that, the mineral oil used for cooling the transformer may deteriorate the paper as well.\n\nAll of the above is speculation based on what I have observed

In a general sense, tensile strength is measured by comparing how much weight a piece of material can hold up.\nOpacity would be measured by shining a light of a known strenght through the paper, and then comparing the value to the strength of the light without the paper inbetween.\nAs to the specific equipment used... I don't know.

Measure of Elasticity of a material. Different temperatures will also change the elasticity of a material.

The type of plastic selected has a great influence on the performance of the plated plastic part. ABS plastics are the base materials in most cases.\n\nCheck out the following:

tensile strength = (2*P)/(pi*t*d)\nwhere; P =maximum load you get from the machine(kPa); pi = 3.14; t = thickness/height of specimen (m) and d = diameter of specimen(m)

The creep of a material can be divided into three stages. First stage, or primary creep, starts at a rapid rate and slows with time. Second stage (secondary) creep has a relatively uniform rate. Third stage (tertiary) creep has an accelerating creep rate and terminates by failure of material at time for rupture.\n\nTo determine creep properties, a material is subjected to prolonged constant tension or compression loading at constant elevated temperature. Deformation is recorded at specified time intervals and a creep vs. time diagram is plotted. Slope of curve at any point is creep rate. If failure occurs, it terminates the test and the time for rupture is recorded. If specimen does not fracture within the test period, creep recovery may be measured.\n\nTo determine stress-relaxation of a material, the specimen is deformed a given amount and decrease in stress is recorded over prolonged period of exposure at constant elevated temperature. The stress-relaxation rate is the slope of the curve at any point.

DSC can be used to measure the extent of reaction in a polymerization reaction (epoxy resin reacting with diamine hardeners, for instance).  At room temperature such a reaction will likely not go to completion as the three dimensional molecule forming "locks up" as it progresses from the liquid into the solid phase.  A DSC can measure the amount of exothermic energy still available in a sample of plastic and, thus, determine how far the reaction went at room temperature.\n\nAll plastics have a point in a modulus vs. temperature curve where the modulus changes most rapidly with the least increase in temperature.  This is known as the Glass Transition Temperature (Tg).  It can be thought of as the point where a plastic behaves more as a rubber like material versus a glass like material at a lower temperature.  A DSC can also measure this.

Volts-drop test.\n\nPut the armature on a V-block powered by a regulated voltage source.  Check the voltage across 2 adjacent com segments and repeat as you rotate thru 360 degrees.  They should all be the same.

Yes. You have to clarify what kind of reinforcement application you are looking for.\n\nComposites - with other fibers, carbon, ceramic etc, Nylon 6 & 66 are used - mostly as fibre mixed with cementitous materials to provide tensile properties.\n\nGeosynthetic fabrics for example are used extensively for reinforcing earth embankments, road substrates & canal sides among other applications.
