Composites provide many advantages for manufacturing under-water structures such as tidal turbine blades, and wave devices. Composites offer strength, fatigue-resistance, corrosion resistance, buoyancy, and cost effectiveness. The needs of a young industry demand more than just a product or service provider. A wide variety of designs, many engineering and materials options, the unpredictable environment of sub-sea and the pressures of bringing new technology to market, require a partner who can see beyond the initial specification.
Gurit has over 30 years experience in innovative composite engineering and materials. From engineering the early advanced composites sailing boats, to patented material technology such as SPRINT™, to wind turbine blade tooling capability for moulds up to 80m and Class-A carbon fibre body panel manufacture for the automotive industry, Gurit has a proven capability to partner new composite applications.
Gurit has a commitment to develop new markets through the application of engineering, materials science, prototyping and manufacture ensuring a coordinated and seamless approach. Gurit‘s size, breadth of experience, entrepreneurial attitude and technical capability make for a trustworthy and credible partner for ocean energy machine developers and investors.

BALLISTICS & DEFENCE
Composites are very versatile materials and offer advantages in many different ways, particularly if the application requires strength and stiffness, with low weight. For the Ballistic and Defence market, laminates provide effective ballistic protection at a much lower weight than metallic armour materials.
Gurit has a track record of innovation in the composites industry spanning 30 years and has recently developed and qualified a ballistic phenolic prepreg, which is now being introduced to the market.
Composite armour works by absorbing the kinetic energy of the projectile as it passes through the laminate. There are three distinct stages involved in the stopping of a projectile: firstly, the blunting or deformation of the projectile, secondly, the slowing phase and, thirdly, the catching of the projectile.
A composite laminate is made up of multiple layers of reinforcement fibres and resin. These layers are engineered to de-laminate at the impact of a projectile. This effect greatly enhances the slowing and stopping of the projectile over other materials. The biggest advantage of composite armour over steel is the significantly lower weight. It can be up to 50% lighter, while providing equivalent protection against projectiles.
Projectiles do not need to be bullets. In fact, artillery or mortar shells, aerial bombs, grenades and antipersonnel mines are all fragmentation devices whose steel casings burst into small fragments when their explosive cores go off.
Gurit’s new ballistic phenolic prepreg PF 700 has been developed with this in mind. It meets the FST requirements and conforms to the threat levels required for this market. It is also suitable for production of flat panels in a press moulding process or for moulding more complex parts by autoclaves.
Gurit’s PF 700 resin has been developed internally with input from industry leaders specialising in defence applications.
