What means Hybrid?
Mixture of different materials with specific
properties combined during processing
What you want:
Powerful combination of all strengths
while avoiding specific weaknesses
What you might get:
Generation of even less applicable combinations
because strengths got lost and weaknesses
remained

Summary and conclusion
• The bandwidth of hybrid solutions is extremely wide
• Many composite related challenges can be addressed with hybrid
approaches.
• Hybrid solutions do require globally or even locally adapted process
• Further improve the understanding of manufacturing processes are
deeded
• Recycling of hybrid components should be included in research
activities.
