- •
Scratch tests with a linearly increasing normal load were conducted for aged PMMA.
- •
The scratch resistance of PMMA decreases with increasing thermal aging time.
- •
The surface crack-initiation strengths of aged PMMA were measured.
- •
The critical normal load well correlates with the surface crack-initiation strength.
