MOOC - Rubber Technologist - Basic Level
Filler Technology
This unit will go into detail on rubber reinforcement by filler technology. Fillers can be non-,semi- and highly reinforcing. For high performance applications rubber is fully filled with highly reinforcing carbon black or silica (silane). These filler are available in in various species which result in different in-rubber compound properties.
Reinforcement mechanisms:
This element will elaborate on the reinforcing phenomena of fillers on micro scale level and how they affect in-rubber properties on macro level.
RUBTECHB.U3.E3.PC1
The student is able to associate reinforcement with more specific in-rubber properties and is able to recognize main reinforcement mechanisms in structure models
RUBTECHB.U3.E3.PC2
The student is aware of the different theoretical approaches for reinforcement with regard to adhesion and filler-filler interaction models
RUBTECHB.U3.E3.PC3
The student is able to identify the loss in shear modulus G* due to strain as being the Payne effect, is able to name one explanation of why it occurs and the effect on application level
