This page will document the work and progress involved in selecting and validating an adhesive option for aero-chassis integration.
Final Adhesive Selected is: EA E-120HP (TDS attached to page)
Document used to compile all the work is here:
...
Figure 1: Images to show complex bonding in MS XIV compared to more basic bonding scenarios
should probably divide this into the scenarios looked at: 2G bump and Crash Scenarios
Make tips for creating simplified model; worst case scenario
go from hand calc approach to simulation set up (features used)
display hand calc results and sim results in an organized table + should show formulas used as equations
lastly talk about design safety factor for adhesives -
There are two main loading scenarios that the vehicle should be designed towards:

The final adhesive decision was E-120HP because it had a significantly longer working life. It has a tensile strength of 41 MPa therefore it will have a safety factor of 20.5. It is reassuring to have a larger than necessary safety factor because as of right now it is uncertain whether the manufacturing of carbon fibre parts and the process of applying adhesives will yield a bond line thickness within the adhesive’s ideal range. This larger adhesive strength will hopefully compensate for any causes for concern.
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.
will probably need to make a test jig hmmm
[To be researched]
