Testing and Validation
The purpose of material testing is to compare the performance of the adhesives produced from our manufacturing ability to the provided technical data sheets. This allows us to have a more realistic understanding of the strength of the adhesive and the quantity of adhesive spent to bond parts together.
The process of deciding on how to begin material testing is based on the provided properties in the adhesive’s technical data sheet (TDS). Each property, e.g. tensile strength, provided by the manufacturer has been tested using specific standards for material testing which will be described next to each property. It would be very important to then research the standards that the manufacturer has used to test their material so that we can conduct our own material testing that is similar to how their experiments were prepared. Note that it may be difficult to find the information on specific standards because they are publications that are sold online. If your research does not yield any literature results, it is possible to try to find the equivalent of a standard as has been done in this material testing for adhesives. It is also possible to find a generic and well-known method of testing for the property being examined which was also done in this material testing.
In terms of the adhesive, EA E-120HP
has been chosen, there were two properties and their standards that were viable for material testing. The first property was the tensile strength (ISO 527-3) for the properties of the cured material. Literature on the testing standard was found, but this test involved manufacturing an adhesive film sample which seemed difficult and irrelevant to our application. The second property was the lap shear strength (ISO 4587) for the performance of the cured material.
will probably need to make a test jig hmmm
[To be researched]
Adhesive Assembly Plan
Will need to design jigs and clamps to apply adhesive and parts together while curing.
