METHOD FOR THE CONTINUOUS PRODUCTION OF LAID STAPLE FIBER FABRICS FROM FINITELY LONG REINFORCING FIBERS WITH ALIGNED FIBER ORIENTATION

摘要

The present invention relates to a method for the continuous production of laid staple fibre fabrics with aligned fibre orientation, in which method the laid fabrics are produced by continuous plaiting down of carded fibre web at defined laying angles onto a synchronized transport belt (1), wherein the carding machine (2) and plaiting means (3) arranged downstream of it are arranged at an acute angle with respect to the advancing direction of the transport belt. Said laid staple fibre fabrics are used for producing high-strength fibre-reinforced plastic composites, as are used in wind power plants, aircraft construction and the automotive industry. In particular in the loading direction, said composites have high composite strengths and rigidities, to which end a defined fibre orientation is required. In addition to a defined orientation of the finite fibres, the laid fabrics also have a defined mass per unit area.
