Method of production and materials
Method of production:
Mareplast manufactures fiberglass boats by using hand lay-up techniques. Hull and deck have sandwich structure.
Gelcoat – modified gelcoat based on isoftalic polyester resin gives the boat good weather resistance and very low water absorption
Resin – isoftalic polyester resin has excellent mechanical properties (i.e. strength), chemical resistance, corrosion resistance, and water resistance.
Foam – low density, two component, closed-cell, rigid foam TRIPOR 227 is used for structural infill of fiberglass components. It gives low weight, excellent strength and makes the hull unsinkable.
Honeycomb core – is used to achieve high stiffness/strength and low weight in order to maximize buoyancy so that boat’s speed can be increased and fuel consumption minimized.
PVC material – inflatable tubes are produced with VALMEX® fabric – a high-quality material that is very elastic, unsusceptible against mechanical damages, airtight, watertight, extremely temperature resistant and dirt resistant.
E-glass fiber – depending on number of layers and orientation of the fibers it is possible to divide multiaxial fabrics into following categories:
Uniaxial or unidirectional
Advantages of multiaxial fabrics over traditional woven fabrics and mats:
- Reinforcement of composite materials in different directions
- Resin consumption 20-30% less
- Weight of end product up to 50% less
- Reduced number of fabric layers in manufacturing and optimization of production process
- Twice higher mechanical strength
- Smooth laminate surface
