2024
To respond more quickly to domestic demand, Tulkas built its carbon fiber plate and profile production infrastructure in 2024. The work targeted not just the production of flat sheets or simple cross-sections, but the joint evaluation of thickness, ply orientation, surface quality, holes and final dimensions according to the load in use.
For plate production, unidirectional, woven or hybrid ply arrangements were made available based on the desired bending stiffness, in-plane strength and dimensional stability. Symmetric ply placement, controlled pressure and temperature application aimed to limit surface waviness and post-cure shape change in the plate.
A workflow was established for post-production thickness, surface, flatness and dimensional control of the plates. Beyond delivering raw plate stock, finishing infrastructure was planned to allow parts to be prepared closer to their final contour on request, using CNC or appropriate cutting methods.
For carbon fiber profiles, outer dimensions alone are not a sufficient definition. Zero-degree fibers matter for lengthwise tension and bending loads, while hoop or angled plies may be needed for torsion, crushing and connection loads. Tulkas built its profile infrastructure with a production approach in which the fiber architecture can be changed according to the intended use of the cross-section.
For box sections, flat bar, tube and application-specific cross-sections, the goal was to carry out mold preparation, ply placement, compression, cure and demolding steps in a repeatable way. The need for local thickening or additional reinforcement at connection regions — unlike a standard commercial profile — could now be evaluated at the project stage.
With this infrastructure in place, Tulkas is now able to develop a suitable plate or profile solution based on load condition, connection type, target weight and delivery geometry, rather than expecting the customer to simply pick a size from a catalog. For small and medium-volume demand, producing samples and validating dimensions locally helped shorten revision times.
The plate and profile capability also allowed Tulkas to prepare in-house the semi-finished materials it needs for its own propeller, fan, rotor and special composite projects. This strengthened the information chain between material, process and final part, while creating a faster and more technically customizable alternative for domestic supply needs.
You can start an application-specific production study for your carbon fiber plate or profile needs by sharing cross-section, load, connection, dimension and quantity information.
