DESIGNING THE PANELS
• Assessing different types of flax fibre.
• Using natural cork as core material.
• Achieving comparable properties to conventional
E-glass with PVC foam core.
WHY FLAX FIBRES ?
• best sustainable alternative.
• very good mechanical properties.
• low or even negative carbon footprint.
• available on the market today.
• good vibration absorbance and strong
noise insulation.
• ideal for high levels of comfort required in top-end products
BEND, STRETCH AND SHEER TESTING OF FLAX FIBRES IN A BIO-BASED EPOXY MATRIX
• Flax showed greater stability than
standard lay-up
• Tension test in accordance with DIN
EN ISO 527
WHY CORK CORE ?
• explored as an organic core material for interior sandwich panels
• very low environmental impact
• alternative to current foam cores
• naturally regrows in 7 to 10 years
• highly water-repellent
• no rot from water absorption
• superior shock and impact protection
• excellent sound insulation due to high
density and granulate structure

RENEWABLE MATERIALS
Building with flax-fibre sandwich panels, the renewable alternative:
- Near identical mechanical properties to conventional composite panels
- Only slightly heavier
- Better fire resistance / retardance
- Flax fibres are hollow, giving more stability on impact
- Cork core has better acoustic properties than conventional panels
- Ultimate sustainability – cork regrows without harming the tree
SUSTAINABILITY AT YACHTWERFT MEYER
- Geothermal heating system at our office building for more than 10 years
- Environmentally integrated wash-down area for boats, protecting the river and surroundings from contamination
- Workshops thermally insulated beyond the norm, heating with the latest technology
- All lights within the yard are LEDs
- Paint shop equipped with air filters to minimise particulate pollution
- Responsible disposal of oil and bilge water, as well as paint
- Use of bio-based oil in all hydraulic machinery and lifting appliances minimises the risk of pollution
- Electric crane, not diesel
- YWM‘s office is going paperless and the company is testing new ways to perform tasks digitally
