Carbon Fibre Recycling from Milling Dust for the Application in Short Fibre Reinforced Thermoplastics

Introductory Chapter: Recycling and Reuse of End-of-Life Carbon Fibre Reinforced Polymers

“…Electrodynamic fragmentation has been used to shred carbon fibre-reinforced thermoplastics. Milling dust and chips produced during milling operations have found applications as fillers in the production of thermoplastic granulates with increase in tensile strength and overall rigidity [14]. Degradation in carbon fibre quality is a key issue affecting mechanical processing.…”

An Investigation on the Feasibility of Fabricating Composites Using Outdated Waste Carbon Fibers and Easily Disposable Polyolefin Resins

“…For the thermoplastic resins used as base materials for the composites, thermoplastic olefin resins show good performance in manufacturing large-area composite structures requiring tensile strengths over 180–240 MPa by high-speed molding [ 20 , 21 ]. Among the thermoplastic olefin resins, polypropylene (PP) is the most basic resin, and polyethylene (PE)-based resins such as high-density polyethylene (HDPE) and low-density polyethylene (LDPE) are also available [ 22 , 23 , 24 ].…”

Development of a Novel Textile Process for the Production of Highly Oriented Nonwovens Made from Recycled Carbon Fibres

“…Existing recycling applications, such as grinding and subsequent compounding in thermoplastics for injection moulding applications, are in fact an extreme form of down cycling due to shortening of the fibres. [1] [2] In the production of nonwovens for the reinforcement of plastics, a high degree of orientation of the fibres can be desired in order to achieve a mechanically anisotropic behaviour of the textile [3]. Classical textile processes, in which fibres are parallelized, such as carding, lead to a significant reduction in length and subsequently of the mechanical properties of the brittle carbon fibres.…”
