Summary
The CUSTOMISIZE project aims to develop a new family of carbon fibres’ sizing in order to improve the interfacial adhesion between recycled carbon fibre (rCF) and polymers (thermoset and thermoplastics) and cementitious matrices. The goal of this is to improve the strength, toughness and environmental stability of the composites prepared with the resized fibre. The specific sizing will be developed for non woven mat and chopped tow of recycled carbon fibres. The new upgraded recycled carbon fibre will be used to produce new composites with cementitious or polymeric matrices (thermoset and thermoplastic).
The proposed strategy is the development of specific sizings for different polymeric and cementitious matrices through the incorporation of coupling agents along with the sizing materials, which through different mechanisms (covalent bond, hydrogen bond, Van der Waals interactions...) will create active points at the CF surface. Those will be responsible for chemical interactions with the matrix. New approaches as the use of Polyhedral Oligomeric Silesquioxanes (POSS), which consist of a rigid organic cubic silica-oxygen core surrounded by eight organic groups, will be used. CUSTOMISIZE also proposes to validate Steam Water Thermolysis, a current method to recycle CF, in the process to introduce chemical functionalities on the fibers that will be able to interact with the sizing. In addition, plasma viability will be studied due to its capability to create new chemical functionalities on fibers and also, the advantages that has compared to industrial electrochemical processes. It is expected to increase the interfacial shear strengths (IFSS) between rCF and the different matrices by up to 90%.
A detailed Life Cycle Assessment (LCA) of the materials and processes will be carried out. These data will be used to assess the impact of the new sizing and its incorporation into different materials, and to support the success of the new developments in terms of sustainabil
