Types Of Degradation In Polymers And Ceramics
This slide concludes the types of polymer degradation into 5 types and make a shortcut for good understanding.
Types of degradation in polymers and ceramics. Bloating is when ceramics turn to rice bubbles like in expanded clay balls used in aquaponics and hydroponics and may or may not be considered degradation. Polymerization techniques santosh damkondwar. While both carbon fibers and matrix polymers are susceptible to oxidative degradation the degradation of the fibers is negligible at the service temperatures envisioned for application of polymeric composites magendie et al 1990. Couses of degradation vi.
How to prevent degradation of ceramics i. Ozawa 52 53 has adapted these equations for random degradation of polymers to the case of constant heating rate kinetics to obtain values for l and the arrhenius parameters from data for the tga of polymer degradation reactions. Thermal degradation ppt of polymers ozagaurang. We will also look at what tests that can be.
Thermal oxidative degradation of polymers most polymers will undergo significant changes over time when exposed to heat light or oxygen. Degradation of an object occurs as a result of the interaction between the environment or with the materials that form the object however in the case of ceramics environmental factors are the major cause. In this report we will draw understanding to fatigue in materials with specific emphasis on ceramics what mechanisms and changes to material microstructure can occur to improve resistance to fatigue. These changes will have a dramatic effect on the service life and properties of the polymer and can only be prevented or slowed down by the addition of uv stabilizers and antioxidants.
