Proving viability of dry fabrics, infusion for large aerostructures

CW has covered several new aerostructure fabrication innovations unheard of a decade ago (see Learn More). Joining those now is a demonstrator wing skin project, unveiled at JEC World 2018, that also breaks new ground. The project is a result of collaboration between Danobat (Elgoibar, Spain) and Airbus Defense and Space (Airbus DS, Cadiz, Spain) and comprises a composite wing skin fabricated using Danobat’s high-speed Automated Dry Material Placement (ADMP) technology, which is well known for rapidly laying wide multiaxial and broadgoods preforms for infusion in wind blade and aerospace manufacturing (see Learn More). The wing skin development partners agreed to share some of this breakthrough project’s details with CW.

Swapping prepreg for NCF

Almost all aerostructures are made today with prepreg materials, which require autoclave cure. But a definite trend is emerging that aims to get aerostructures out of the autoclave. That’s the premise behind the wing demonstrator, says Asier Gandarias Mintegi, Danobat’s manager of composites business development: “Our goal is to show the feasibility of manufacturing aircraft components by means of fully automated, dry, multiaxial non-crimp fabric deposition, to achieve disruptive high production rates.”
