In these directions the layers offer a comparatively good interlaminar slip and accordingly the GRP easily emerges. In fibre direction, however, only a slight or no squeeze-out at all of thermoplastic was observed. The fibres cannot be extended; accordingly an extension of the GRP in this direction can only occur when either the fibres or fibre layers slide on each other or the thermoplastic is forced out between the fibres. The large surface area and associated friction between thermoplastics and fibres is obviously sufficient to prevent excessive squeezing-out of the GRP in this direction.
