Future research highlights

Macro-meso structural level

• damage/forming/permeability models fully integrated with virtual textiles and micro-CT
• full meso-macro integration of textile/random fibre composites models
• integrated numerical tools and material characterisation for out-of-autoclave

Micro-nano structural level

• hybrid composites with a “frog leap” in toughness
• scale shift of damage in nano-composites; tough materials exploiting this principle
• atomistic, molecular dynamics and meso-scale modelling integrated with continuum

mechanics of heterogeneous media Natural composites

• bamboo technology is spin-offed
• flax European integration, technical standards for flax reinforcements
• Set-up of durability assessment infrastructure (including interfaces) and first treatments

Process and application development

• Integrated numerical-experimental optimization methodology for thermoforming
• Natural fibre and biopolymer applications in extrusion and IM
• Bicycle helmets and test standards for rotational impact

Actions for 2015-2020

CMG approaches to sustainable research: 1. Diversification of funds (EU : Flanders : KU Leuven : Industry : International) 2. Sequence: fundamental (C1, FWO, some EU, SBO) applied (C2/C3, EU, O&O, Industry) 3. Project duration at least 2 years (industry), 3-4 years public funding. 4. Collaboration with SLC on applied, process and application projects, and on knowledge dissemination 5. Industrial network, solid university partners in Flanders, large EU/Japan/Russia/USA network 6. Selectivity in partners choice (“top”), combined with “trial” collaboration 7. Visiting researchers and International Scholars 8. Cluster funds, create teams, enhance inter-project exchange 9. Commercialise, but keep open scientific exchange Topic Aim Targeted actions Rem arks Potential MTM-related short term actions
