Changes After Testing
Although the pegs did fall off under a crash scenario (a sizable force applied to the crown of the helmet), we found that the glue joints holding them onto the insert were too brittle for our liking. Some of the pegs would fall off with even the slightest pressure applied to them, meaning the wearer would get showered with little pegs as he removed the helmet. To counter this we rebuilt the prototype while using a stronger glue, and redid the testing. The test results displayed above are from the second insert design, the one with the stronger glue.
Summary
Adviser's Notes:
- Glue was too brittle
- Find a stronger glue, that would cure faster
