The overall objective of the »Cider« project is the development of sustainable, recyclable and recycled composite material for the transport sector. This will be achieved in developing three demonstrators over multiple life cycles of the fiber and polymer material. The detailed objectives are listed below:
Objective 1: Design and engineering of 100% recycled and recyclable demonstrator parts to replace actual steel variants. Through the sustainable and circular design of a metal free hydrogen tank and its recycling, a second-life automotive part with 100% recycling rate can be achieved. This provides a high reclamation of all materials for a cradle-to-cradle approach. »Cider« will work with recyclable matrix material and use rCF as the input materials.
Objective 2: Development and production of novel nonwoven material from recycled carbon fibres. »Cider« will develop a production technique for rCF material with higher mechanical properties to pave the way for the widespread use of recycled materials due to the application of a web drafter.
Objective 3: Substitution of critical raw materials. Through the circular use of composite material, the consumption of critical raw materials such as magnesium, which is used as an alloying element in aluminium in the 5000s and 6000s alloying series, niobium, which serves to enhance stiffness of steel or titanium, which is widely used in aviation applications, can be substantially decreased.
Objective 4: High quality insurance of the automotive part. Through the novel nonwoven technique the homogeneity of rCF nonwoven material will be improved. The design and simulation of rCF components will be enhanced through further testing and quality tasks of the rCF-parts.
Objective 5: Holistic approach in a closed loop economy. The hydrogen tanks will be recycled into two sustainable second life demonstrator composite parts. »Cider« will even go beyond the second life application and develop possible third life products to provide a circular material solution and decrease the consumption of virgin raw material.
