Abstract

Es wird ein transparentes Ballistik-Schutzsystem mit mindestens einem Bauteil aus einer polykristallinen Keramik oder aus einem Einkristall und mit einem das mindestens eine Bauteil zumindest partiell bedeckenden Matrixmaterial beschrieben, wobei das mindestens eine, vorzugsweise nicht nachbearbeitete, Bauteil einen optischen Brechungsindex nB und das Matrixmaterial einen daran angepaßten optischen Brechungsindex nM aufweist, mit
nB= a.nM,
mit 1,1 ≥ a ≥ 0,9,
so dass das Schutzsystem bei einer Wellenlänge von 300 nm, 500 nm, 700 nm, 1000 nm, 2000 nm oder 4000 nm eine RIT (Real-Inline-Transmission) von >10% aufweist.The invention relates to a transparent ballistic protection system having at least one component made of a polycrystalline ceramic or a single crystal and having a matrix material at least partially covering the at least one component, wherein the at least one component, preferably not post-processed, has an optical refractive index n B and the matrix material has an adapted optical refractive index n M , with
n B = to M ,
with 1.1 ≥ a ≥ 0.9,
such that the protection system has a RIT (Real Inline Transmission) of> 10% at a wavelength of 300 nm, 500 nm, 700 nm, 1000 nm, 2000 nm or 4000 nm.
