Influence of fibre length and concentration on the mechanical properties of long glass fibre reinforced polyurethane

Glass fibre reinforced polyurethane plates automatically manufactured with the polyurethane fibre spraying process were studied with respect to the fibre length and the glass fibre mass content to determine their influence on the mechanical properties. The glass fibre mass content was varied in 5 wt. % steps from 0% to 30%. The length of the glass fibres was 6 and 12 mm. As matrix material a fast reaction polyurethane system was used. Mechanical properties were investigated by tensile tests, 3-point bending tests and Charpy impact tests. Specimens were taken in and orthogonally to the direction of the spraying head movement.
