Sustainable Carbon Fibers Manufacturing from Bio-Based Precursors

Job Description:

1. Introduction UM6P:

Mohammed VI Polytechnic University is an institution dedicated to research and innovation in Africa and aims to position itself among world-renowned universities in its fields. The University is engaged in economic and human development and puts research and innovation at the forefront of African development. A mechanism that enables it to consolidate Morocco's frontline position in these fields in a unique partnership-based approach and boost skills training relevant to the future of Africa. Located in the municipality of Benguerir, in the heart of the Green City, Mohammed VI Polytechnic University aspires to leave its mark nationally, continentally, and globally.

1. Context:

Carbon fibers (CFs) are high-performance engineering materials widely used across multiple industries, such as aerospace, automotive, and energy storage. Their exceptional strength-to-weight ratio, electrical conductivity, and thermal stability make them well-suited for fiber-reinforced composites for structural applications. They can be produced from a variety of precursors, with more than 95% of the global supply currently originating from polyacrylonitrile (PAN), which relies heavily on petrochemicals.

Carbon fiber production is notably energy-intensive, with the PAN precursor alone contributing over 50% of total manufacturing costs using conventional methods. Therefore, current research aims to lower costs by improving energy efficiency during the different heat treatment stages, as well as exploring alternative precursors derived from renewable resources or industrial waste. Indeed, bio-based precursors for CF production are gaining increasing interest as sustainable and cost-effective alternatives to petroleum-derived precursors. Materials such as lignin, cellulose, and algae-based polymers offer the potential to reduce the environmental impact of CF manufacturing by using renewable resources and lowering fossil fuel dependency.

However, scaling these processes from laboratory to industrial levels remains challenging. Key barriers include inconsistent precursor quality, fiber instability during heat treatment, and high energy demands. Maintaining or improving the mechanical performance of the final fibers is also essential for their use in demanding sectors like aerospace, automotive, and construction. Ongoing research and technological advancements are anticipated to address these challenges, enabling the wider commercialization of bio-based carbon fibers.

1. Research objectives:

This PhD thesis will focus on:

• Developing novel bio-based formulations to enhance carbon fiber precursor properties,
• Scaling up spinning, stabilization, and carbonization processes with improved energy efficiency and control,
• Enhancing the mechanical and thermal performance of bio-based carbon fibers for high-performance applications,
• Performing life cycle assessment (LCA) and techno-economic analysis (TEA) to assess environmental and economic viability.

Admission Criteria:

• A master's degree or equivalent in Materials Science & Engineering, or Textile Engineering.
• Previous experience and practical skills in at least one of the following fields: wet- and melt-spinning technologies, fibers drawing, structure-property relationships in carbon fibers, synthesis of advanced carbon materials synthesis, and fibers surface chemistry.
• Proficiency in both written and spoken English is necessary.
