Abstract
A transparent plastic pane of acrylic glass with internal plastic filaments, which largely hold together the fragments formed in the event of a break characterized in that the plastic filaments are at least partly sized. The internal filaments can be sized completely and/or partly, for example in portions. Hereby the matrix adhesion of the filaments can be adjusted to the effect that any fragments which may be formed in the event of break are largely held together by the filaments without permitting undesired detachment of the filaments during thermal stresses in the normal range of −20 to 120° C. The plastic panes are suitable in particular as a noise protection wall.
