Can anyone help me in finding a standard/paper for testing cure times of polymeric materials? or the bond strength of polymeric materials with repsect to the cure times/cold temperatures? For more information in why i need this see my previous question dated and titled:

dropped object analsysis is an important task to be taken particularly with reference to offshore pipelines. These pipes are designed with sometimes 4,5 or 6 coatings and are manufactured in a way to minimise heat loss so hydrocarbons do not cool and form solids which would subsequently block...
if you know anyone in the buisness or have got $500 spare, you need to get hold of the "IADC, (international assosciation of drilling contractors) drilling manual". I just came out of university 6 months ago, and this document i had at work experience tells you every single thing you need to...
There are two theories that exist on the formation of oil. The most commonly accepted one is the 'organic theory'. That is, over the past millions of years, organic material, such as plant growth etc decomposes over time, and through the cycles of the ocean, becomes buried deep underneath the...
Thanks for the attention/tips!
what i'd like to know is how much heat is tranferred away from the surface of the multilayered pipe. Since the top layer is injected moulded polypropylene, it is 'cooling rate' and 'strain rate' dependent.due to shrinkage with cooling, the level of strain depends...
Thanks for the attention P.
The first layer is an FBE, 2nd layer is copolymer adheseive to join the (difficult to bond) FBE to the 3rd layer of PP foam. I think the PP is homogeneous in nature if thats what you are asking. What does 'embitterment' point mean? i'm new to this stuff. (i have...
*Need Brains to Pick*
Currently i am investigating the failure of Injected moulded polypropylene used as a field joint for an offshore pipeline. The assembly process at the end of the 'stalks' of pipeline, i.e. where the 'factory' coating ends, is as follows (neglecting contaminents):

Dear all.
Currently i am investigating cooldown times from a multilayered pipe. I need help in finding an experiment to determine the film coeffcient of polypropylene, is this worth doing or should i just take a conservative value found in the (large) range given online?
Thanking in advance.
