Area of Science:

  • Materials Science
  • Additive Manufacturing
  • Computational Modeling

Background:

  • Poly-ether-ether-ketone (PEEK)/carbon fiber (CF) composites offer high specific strength and modulus, but PEEK/CF components made via powder bed fusion (PBF) additive manufacturing often exhibit brittle fracture.
  • Defects like poor interfacial affinity and inner voids in PEEK/CF components are linked to suboptimal powder packing quality during deposition.
  • Understanding and improving powder deposition mechanisms are crucial for enhancing the performance of PBF-manufactured PEEK/CF composites.

Purpose of the Study:

  • To develop an efficient and systematic material evaluation method for composite powders to investigate their deposition mechanism.
  • To utilize the discrete element method (DEM) to simulate the dynamic behaviors of PEEK/CF composite powders.
  • To analyze the influence of short carbon fiber addition on the flowability and packing quality of PEEK powders.

Main Methods:

  • Calibrating and justifying powder properties, bulk material properties, and interfacial features using experimental measurements, numerical simulations, and design of experiments.
  • Employing the discrete element method (DEM) to model the dynamic behaviors and interactions of PEEK/CF composite powders.
  • Conducting experiments to measure powder flow and packing quality, comparing results with DEM simulations.

Main Results:

  • The particle dynamic model successfully explains powder flow behaviors and interactions, with experimental and simulation results showing a maximal deviation of 4.89%.
  • Addition of short carbon fiber (CF) particles was found to assist the flow of PEEK powders and improve the packing quality of the composite powders.
  • Experimental improvements in packing quality of 31.3% and 55.2% were observed for PEEK/CF_30wt% and PEEK/CF_50wt%, respectively, with simulated improvements of 27.4% and 50.2%.

Conclusions:

  • The developed discrete element method model provides a reliable approach for evaluating composite powder deposition mechanisms.
  • Incorporating short carbon fibers into PEEK powders significantly enhances powder flowability and packing density, crucial for improving PEEK/CF composite quality in additive manufacturing.
  • The findings suggest a viable strategy to mitigate defects in PEEK/CF components produced by powder bed fusion, leading to enhanced material performance.
