MANUFACTURE OF COMPOSITE STRUCTURES

Composite Shop is currently equipped with the infrastructure necessary to carry out the following processes:

 

1. Manufacture of main rotor blades, tail rotor blades and horizontal stabilizers for Mi-2, W-3, SW-4, Kania helicopters as well as for the manufacture of composite liners:

-dryers for composites ( max. temperature: 220°C, max. dimensions: width: 2800mm x height: 2200mm x length: 8500mm, with computer  recording of polymerization parameter),

-115 sq.m painting shop.

 

2. Manufacture of composite structures in clean room:

-3 clean rooms (the largest is 630 sq. m in size),

-VIRTEK 8-head laser projection system,

-2 plotters for prepreg cutting: LECTRA, HUMANTEC,

- 4 autoclaves (the largest with a diameter of 3500mm, 10000mm long),

- 9 cold rooms.

3. DT and NDT inspection:
-UT Pulse Echo ASCAN manual inspection of the monolithic structures, 
-UT Through Transmission ASCAN manual inspection of sandwich and bonded structures, 
-UT Through Transmision C-SCAN automatic inspection  of the monolithic, sandwich and bonded structures  (flat and slightly curved parts),
-UT Through Transmision NU-SCAN automatic inspection  of the monolithic, sandwich and bonded structures  (parts with complex 3D curvature).  


4. Machining:
-5-axis CNC milling centers by JOBS - JOMACH 146®  (with overall dimensions worktable X: 6000 mm, Y 4000 mm, Z: 2000) and  JOBS - JOMACH 156® (with overall dimensions worktable X: 4800 mm, Y 3200 mm, Z: 2000 mm),
- 3-axis milling machine (plus indexed axis C) 4030 NOVA 3X with vacuum table with dimensions of 3m x 4m.

 

5. Design, simulation and manufacture of bonding tools:
-design and simulation, carried out with up-to-date CAD/CAM tools (Catia, NX, AutoCad), 
-fiber development and nesting (Magestic software),
-manufacture of metal tools, composite tools using wet lay-up, pre-preg,  infusion or pattern plate technology,
-tools refurbishment
