DESCRIPTION

This project deals with the implementation of Digital or Hybrid Twins in the manufacture of composite structures.

carbon fiber reinforced plastics (CFRP) used as structural components in the aerospace industry and in vehicles.
electric. This technology is an out-of-autoclave composite forming solution based on the infiltration of liquid resins.
Its implementation is proposed both for structures manufactured with conventional technologies as well as for additive manufacturing (ALM, Additive
Layer Manufacturing) in carbon fiber with thermoplastic matrix (PEEK).
A conceptual change based on the knowledge of infusion or re-infiltration manufacturing technologies is proposed for the
repair of large composite structures. This new repair concept is associated with the development of twins.

In recent years, additive manufacturing processes have made it possible to reduce costs thanks to the capacity of generating
very complex geometries and above all the possibility of realizing very light structures thanks to topological optimization techniques.
These processes comply with the commitment to sustainability in manufacturing and allow for up to 90% reduction in energy savings and
only 5% of waste material. Therefore, this project is perfectly linked to the sustainable transport challenge.
We propose the study and implementation of the technique to the advanced manufacturing processes of carbon fiber with PEEK matrix by
additive manufacturing. Knowledge of 3D modeling of micro-cracks and impregnation is essential for this project,
crack growth, composite impact, quality control by non-destructive testing (ultrasonic and thermography), modeling, etc.

generated the digital twin, augmented reality techniques will be used to assist the technical personnel in charge of carrying out the
component repair.
This project is part of the research line of the Universidad Politécnica de Valencia (UPV) in the field of
composites, in which five projects of the National Plan have been developed (Ref.: DPI2001-2792, DPI2004-03152, DPI2007-66723-C02-
