Chip & Cut Module
The chip and cut module measures the material’s resistance to damage from impacts with sharp surfaces. This test can be related to real-world conditions that lead to pitting and chunking of rubber surfaces. It is essential for tire tread materials and other applications subjected to wear via contact/impact with rigid, macro-scale, small-radius, convex surfaces such as stones.
Recommended for cases where harsh or abrasive environments may cause cutting and chipping on an
elastomeric contact surface.
Experiment Overview:
• Tested on Coesfeld Instrumented Chip & Cut Analyzer (ICCA©)
• Indenter pushed into round rotating specimen w/repeated impacts
• Experimental data recorded: Normal force, tangential force, and indentation depth as a function of time for each impact
• All tests performed at lab ambient temperature (23°C)

Analysis and Reportingn/ Deliverables
• Test data evaluated to determine Chip-Cut damage parameter, P, by integrating the fluctuations in tangential force. A lower value of P indicates greater resistance to chip-cut damage.
• Weight loss recorded during experiment
• Images of specimens before and after testing
Peak normal force, impact duration and frequency are specified as test inputs. Longitudinal friction force and indenter penetration are monitored during the test.
Images of test specimens show wear damage that occurred during the test. Mass loss is reported along with Coesfeld’s P parameter.
Use with:
• Tire tread applications
• Belts – especially in mining
• Impact damage applications
