A New Spectroscopic Method for the Non-Destructive Characterization of Weathering Damage in Plastics A New Spectroscopic Method for the Non-Destructive Characterization of Weathering Damage in Plastics
A recent problem that arose at Superyacht Solutions, a boat repair company in Australia, required a solution to just this problem. Such a test was developed for Superyacht Solutions, and is being applied across a wide range of plastic materials. The chemical foundation upon which this solution rests is also being confirmed.
The Superyacht Solutions problem was that a boat was brought in for repair which was yellowing dramatically. Surface erosion was confirmed by scanning electron microscope (SEM) surface studies. A loss of mechanical properties was also suspected. A new spectroscopic method of analysis was developed that not only identified the problem as extensive oxidation, but was able to quantify the extent of damage that occurred through a non-destructive technique. This method has also been applied to other plastics with encouraging initial results. The method used and its theoretical basis are included in this thesis.
