Failure Analysis of Fiber Reinforced Injection Moldings Using a Composite Lamina Failure Approach
Collapse Expand


This class will demonstrate how the use of experimental test data of several tensile specimens of varying fiber orientation can help determine an adequate failure criteria for a given reinforced thermoplastic. This criteria can then be utilized to better predict failure of complex part designs with widely varying fiber orientations. Data for a 30% glass-reinforced PEEK material will be shown as an example of this approach to orthotropic failure analysis.

Key Learnings

  • Better predict the strength of any fiber-reinforced injection molded part design
  • Demonstrate the importance of orthotropic structural analysis for good design
  • Demonstrate how the lamina failure approach plays a key role in predicting injection-molded strength
  • Show the need for further structural research of fiber-reinforced materials
