You find a brand-new, premium fiberglass motorcycle helmet that has been stored untouched in a box for 8 years. Is it safe to wear?
A)Yes. Since it was never used or exposed to sweat and sun, the materials are completely fresh.
B)Yes. Fiberglass does not degrade over time unless it is involved in a crash.
C)No. Even if unused, the internal protective foam naturally hardens and loses its impact-absorbing ability after 7 to 9 years.Correct
Even in a box, the internal protective foam (EPS) and structural resins naturally degrade and dry out over time. After 7 to 9 years, the materials become too brittle to absorb an impact safely, making the helmet useless in a crash.
