The goal of the Business Unit Delta Carbon Fiber
Technologies is the manufacture of composite parts,

with out-of-autoclave processes, both impregnation and prepregs

This activity is carried out in our Delta Illescas plant. We have at our disposal an 8,000 m2 workspace with all of the necessary production resources:

  • Clean room of 1.700 m2 Class 8 (EN ISO 14644-1)

  • Robotized installation for the manufacture of preforms

  • Resin injection machine for impregnation processes (DRTM, DLRI)

  • Cutting machine

  • Ovens (up to 5000 x 3000 x 2500 mm)

  • Freezer (5000 x 3900 x 5500 mm)

  • Machining/milling centers (on five axis up to 24000 x 3500 x 2000 mm)

  • CNC Software tools (CATIA and TEBIS)

  • Ultrasonic inspection equipment (US): pulse-echo and phase array

  • Priming and paint booth

Thanks to the joint work of our R&D and Manufacturing Engineering departments since 2009, four patents have been successfully issued for the development of a new automated manufacturing process for composite preforms

OUTSTANDING RESULTS

DRTM and DRLI

Frames

  • Fibers orientation optimization

  • Great reduction of the distortion of fibers: this allows for the fabrication of parts in carbon fiber, which are not currently attainable by means of conventional techniques

  • Without wrinkles, undulations or impregnation defects

  • Precision of the tolerances and excellent dimensional repeatability

  • Flexibility in the configuration of the part, allowing for design and structural weight optimization

  • Methodology of control and correction of the spring-back

  • Cost-benefit ratio extensively improved

  • Reduction of manufacturing lead-times (improvement of the reactivity)

  • A very significant improvement of production rates compared to conventional processes

Panels

  • Applicable to any type of stiffened structure (such as spars, ribs, stringers, fittings and frames)

  • Double curvature panels with integrated stiffeners and manufactured in one-shoot process

Roving

  • Homogeneity of the fiber distribution

  • Fiber volume (58%)

  • Adaptable to any typical filler geometries
