A method for producing fibre-reinforced moulded bodies comprising an organic matrix based on thermoplastic cellulose esters is disclosed. In said method, reinforcement fibres together with fusible fibres, each in the form of continuous fibres based on cellulose esters, are converted into a textile fabric, the thermoplastic cellulose esters of the fusible fibres having a melt flow index MFI (according to DIN ISO 1133) of 1.0 to 30 g/min (245°C) and the fusible fibres having a linear density (according to DIN 53812) of 0.5 to 40.0 dtex, a tensile strength (dry) (according to DIN 53816) of 2 to 40 cN/tex and an elongation at break (dry) (according to DIN 53816) of 3 to 40. The textile fabric obtained is heated in order to fuse the fusible fibres and to form a fibre-reinforced moulded body. Also disclosed is a fibre-reinforced moulded body produced according to said method, wherein 1.) the thermoplastic cellulose ester has a melt flow index MFI (according to DIN ISO 1133) of 1 to 50 g/min (245°C) and 2.) the fibre-reinforced moulded body has a flexural modulus (according to DIN EN ISO 527) of 1,500 to 20,000 [MPa], a tensile strength (according to DIN ISO 527) of 150 to 600 [MPa] and/or a modulus of elasticity (according to DIN ISO 527) of 1,000 to 5,000 [MPa]. The moulded body can be advantageously used, in particular as a construction part, in the automotive industry. In addition, carbonised moulded bodies can be produced therefrom. |
