R&D - ADVANCED COMPOSITE MATERIALS PROCESSING METHODS BEST PRODUCT COMPETITIVE PRICE

 

Stemar Nautica was founded as Marine Division of Marcelli’s group of Company. The family is operating since 1880 in the environment protection and natural resourcefields.


Under the leadership of Alessandro Marcelli is operating with the intent to produce a new generation of military and professional boats: stronger, lighter, faster runnig and with lower operational costs.


To achieve this objective it was built a new shipyard with the most modern equipment, machinery and sophisticated 3D CAD and CAM software for the construction of models and molds.

 

A team of engineers, architects and highly qualified technicians, specialized in advanced composites, are able to study, design and build any type of structure, providing products "custom made" turn keys.


The shipyard builds its boats in advanced composite used for the construction of Racing sailboats and many off-shore speedboats partecipating in the World Championship.


Our boats are “custom made”with a lifetime guarantee against “osmose”, also designed as a multi-role technology platforms, providing a wide range of: mission profiles, autonomy, adaptability, ballistic protection and specialized equipment for any operational requirements.

  • (CAM) programs for mould construction-axis
  • Controlled temperature room up to + 85° C and 20% humidity for epoxy resin processing A temperature-controlled room for resin’s storage.

 

EXPERTISE AND CERTIFICATION


Company consultant:

  • University of Perugia faculty of Engineering

 

Quality certifications:

  • ISO 9001:2008 certification from DQS ITALY - Professional boat design and construction

 

MATERIALS AND WORKING METHODS


To achieve best results of lightness and strength below specified, the shipyard
uses only:

  • epoxy resin (which has multiple and ultra resistant molecular bonds)
  •  "vacuum bag" lamination to give 100% of a perfect cohesion between the layers of reinforcement and maximum lightness.

 

PRODUCTION STAGES


STEMAR can satisfy the entire production cycle including:


PROJECT

  • Understanding of customer requirement;
  • Worldwide research for boats having similar specification;
  • Selecting the best solutions;
  • Design of a new boat that has all the best solutions plus STEMAR materials and construction processes.                                                                                                                                         

DRAFT REWIEW

  • Construction of the model scale 1 to 5 with CNC 5-axis;
  • Static and dynamic tests of the model 1 to 5 scale;
  • Possible design review on the basis of test results;
  • Structure certifications by R.I.N

 

CONSTRUCTION

  • Model scale 1:1 with CNC 5-axis;
  • Mould;
  • Entire boat including engines, electronic and equipment assembly.

 

TESTING

  • Preliminary operational tests;
  • Final test and delivery to customer.
