Answers:
I currently design boats, mostly catamarans of all kinds. I was the pioneer of using foam sandwich construction (PVC foam core with resin/glass fiber skins). I have developed and refined the use of these materials ever since. We have our own unique build methods, KSS (Kelsall Swiftsure Sandwich) which is the most efficient way to build the boats. It is based on making a kit of flat panels on a full length mould table. Resin infusion is the laminating method. The basic plastic materials have changed little over the 46 years since my first use of them.

Injection molded parts both reinforced with glass and carbon and non-reinforced. Thermoformed parts. Extruded parts. Rotomolded parts. I also have a lot experience with Continuous fiber reinforced thermoplastic, RTL (Reinforced Thermoplastic Laminates) pressured formed. I also have a number of years of thermoset composite laminated experience. I have Tooling Design and Part Design as will as manufacturing experience. My expertise is in the area of problem solving, trouble shooting problems and root cause analysis.

Q:
Please share with us any “non-standard” applications that polymers and plastic materials have been used for.
41 answers
Answers:
I and a colleague designed a plastic umbilical clamp for offshore industry. There are other variants in PE, but we made one with good grip force. There are also rubber variants but then with very low grip force. I wish to have a plastic that does not relax in temperatures up to 110 degrees celsius for months, are robust against heavy impact loads, resistant to mineral oils and pH levels up to 14,5. Low density and cheap. Easy to mould and to machine.
~Engineering, Design, Oslo, Norway
Most of the applications I've worked on have been more-or-less standard, although the fact that they are intended for use in medical devices adds complexity.
~Research & Development, Wilsonville, OR

Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of polymers and plastic materials?
28 answers
Answers:
Selecting a material class too soon resulted in a long and costly engineering process, that in the end didn't succeed. The whole development and engineering process had to be done all over again. The product (office machine) was years later on the market and wasn't competitive any more. So too much haste at the start resulted in the end in long delay!
~Niels S, Engineering Consultant, Nijmegen, Netherlands
Poor choice of materials and or bad design created the term “Cheap plastics!” “localized fastening” is why those plastics break, tighten the screw down too tight. That is the very reason the most suppliers are now using the term polymers or engineering polymers to get away from the term plastic.
~Gene Jackson, Engineering Consultant, Deer Park, WA
Often the wrong type of plastic is specified for the application (normally for cost reasons), or inexpensive tooling is built where better tooling is necessary. These situations often lead to disappointing results.
~Bill M, Senior Mechanical Engineer, Round Rock, TX
We have chemical compatibility issues with some most reactive polymer types. This has caused issues when materials have been implemented large scale without being properly validated small scale.
~Renai, Materials Scientist, Deeside, UK
Yes the gas which comes out of POM by longer machines stops without reducing the barrel temperature can turn your machine nozzle into a missile when it is blown out of the barrel.

Yes, rough (Microscopically) has led to disastrous deposition of minerals almost calcifying the polymer into a stone.
