ExoMarine™

Super tough, hydrophobic composite material that can recovered, recycled and reused repeatedly.

In 2017, the Marine Industry, in conjunction with METS, estimated that worldwide, somewhere between 35 to 40 million boats are now approaching the end of their life. The challenge is that no one wants to touch them because there is no money to be made in scrapping old boats. Right now, the vast majority of old boats are simply cut up and buried in landfill. But with literally tens of millions of boats headed for the dump over the next several years, and each hull having the potential to leech a variety of toxic chemicals like formaldehyde into the ground water, end-of-life boats represent a growing problem.

ExoMarine™ presents a ‘fit for purpose’ and viable solution in response to this global ecological crisis by providing an accelerated green transition to a circular economy for the maritime industry. The development project has created a full-scope “pathway” for boat manufacturers using conventionally infused composite material to rapidly transition to ExoMarine™ without the requirement for extra investment in production methods or resulting in a material increase in the cost price of the end product.

Certification

In April 2021, ExoTechnologies commissioned an independent market-leading specialist material science and engineering laboratory to evaluate ExoMarine™.

Specifications

ExoMarine™ has been tested against the following internationally recognised standards:

  • BS EN ISO 62 : 2008
  • BS EN ISO 527-4 : 1997
  • BS EN ISO 527-5 : 2009
  • BS EN 2850 : 2017
  • BS EN ISO 14125 : 1998 + A1 : 2011
  • BS EN ISO 14127 : 2008
  • BS EN ISO 14130 : 1998
  • ASTM D5379-19

Test specimens were cut and end tabbed, as required, from the supplied laminates. Samples were end tabbed using a printed circuit board glass fibre material, bonded with a paste adhesive. Test samples were allowed to condition in the laboratory at 23 °C ±1 °C and 50 % RH ±5 % RH,  for a minimum of 16 hours prior to testing.

Samples taken from random locations on three of the supplied laminates were sectioned and then cold mounted. These samples were then ground and polished to a 1 micron finish prior  to microscopy images being taken for qualitative void content determination. The void content was determined using Image J image analysis software to an in-house procedure. Microscopy images are shown in the appendix.

‘Wet’ properties were determined on laminate specimens which had been immersed in distilled water for 28 days at 35 °C ± 2 °C, dried and then tested immediately.
