Effect of basalt intraply hybridization on the damage tolerance of flax laminates: Experimental analysis and analytical modeling under low-velocity impact


Elena Raponi, Balthasar Fischer, Josef Pörnbacher et. al.

  • Flax, basalt, and hybrid flax/basalt/epoxy composites were subjected to low velocity impact tests to study their toughness
  • The samples were subsequently investigated using XARION’s contact and couplant-free Laser Excited Acoustics (LEA) method
  • The LEA method allowed detection and quantitative assessment of internal damages in the different composites
