PRESS RELEASE

November 2017               

                                                                                                                                     

EMMA will develop lightweight low-cost multi-material structures for the automotive industry

 

  - In the EMMA project, hybrid polymer-metal composite structures will be developed with the objective of replacing components made from more traditional materials at a competitive cost.

  - As part of the ConectaPEME 2016 Programme, the project consortium is led by LEAR CORPORATION and it is completed by the companies RCASTRO, PLASCIES, UNTHA y DEMSU. AIMEN participates as a collaborating entity.
 
  - The new multimaterial structures developed will allow the reduction of the weight of the vehicle by 30-40% while maintaining its mechanical characteristics.

 

EMMA is an integrated project of a strategic nature, in which novel technologies for the manufacture of multimaterial structures of great interest to the automotive sector will be developed, both in Galicia and internationally.

Its main objective is to develop hybrid polymer-metal composite structures (PMH) that will be integrated into a unique subset for the replacement of automotive structural components made of traditional materials. In this way, it will be possible to achieve at a competitive cost, a weight reduction of 30-40% while maintaining its mechanical capabilities through localized reinforcement by means of suitable design composite inserts from regions subjected to greater mechanical stress.

This second year, it has has a major impact on those activities related to surface engineering and joining technologies. In this way, the development of novel technologies such as laser texturing and plasma treatments has thus managed to maximize the resistance of the dissimilar joints. In this line, in addition, different strategies are being developed in order to avoid the formation of a galvanic pair. In this sense, it should be noted that this is one of the barriers to be solved in multi-material design based on combinations of steel and carbon fiber, therefore generating great interest. On the other hand, the manufacturing processes for the different strategic routes proposed by the project have been carried out, in a wide range of materials, which is highly linked to the redesign and optimization of the current component.

 

Intersectoral Collaboration

The EMMA Project, with a budget of 896.466,14 euros and a total duration of 34 months, is part of the ConectaPEME 2019 Programme.

The Companies participating in EMMA cover the entire value chain of the project. LEAR CORPORATION (formerly GA-PGA) project cordinator and leader in the manufacture of automotive components, RESINAS CASTRO, a company specialised in composite materiales, PLASCIES, with extensive experience in thermoplastic materials and their manufacturing processes, UNTHA, specialised company in solutions for recycling and, finally, DEMSU with great knowledge in the design of molds and custom tools.

EMMA also has the collaboration of the AIMEN Technology Center, with great experience in the proposed lines of research and where its main contribution is focused on the optimization of the metal-composite bond. In this way, AIMEN will investigate different joining technologies and different strategies to maximize its resistance, guaranteeing, in short, the performance of the  component.
