Furthermore a ballistic resistant moulded article is disclosed based on compressed ballistic resistant sheets combined with a ceramic strike face, optionally with a metal layer between the ceramic strike face and the ballistic resistant sheet. There is no mention of a 3 layer fiber based hybrid structure with tailored use of different matrix material per layer.
A ballistic resistant sheet is known from US2012/0244769. This publication discloses a method of producing a composite with a non-uniformly distributed matrix material. Example 1 discloses an aramid based unidirectional composite material with inhomogeneous distribution of a polyurethane-based matrix material, whereby a scrim material is bonded to the resin poor surface of the composite. This composite together with the same composite, however without the said scrim, are combined in a mould and compressed to form a shaped article. There is no mention of a 3 layer fiber based hybrid structure with tailored use of different matrix material per layer.
Preferably, each monolayer in the multi-monolayer sheet contains the UD oriented reinforcing fibers with the fiber direction in each monolayer being rotated with respect to the fiber direction in an adjacent monolayer. Such a ballistic resistant sheet is very suitable for use in compressed or moulded ballistic resistant articles such as panels and especially curved panels and articles (e.g., inserts, helmets, radomes). An alternative use of the ballistic resistant sheets of the embodiments disclosed herein, being a multi-monolayer construction including a core layer formed of at least one, preferably at least two, first monolayer comprised of first unidirectionally oriented reinforcing fibers and an elastomeric matrix material which is sandwiched between respective face layers, relates to soft ballistic articles, such as bullet-resistant vests.
There is continuous drive towards improved ballistic resistant articles, including moulded articles that enables the manufacture of compressed panels or ballistic resistant moulded articles with improved mouldability. Improved mouldability means that upon moulding of a ballistic resistant article, especially a curved ballistic resistant article, comprising several ballistic resistant sheets, a homogeneous product is obtained (i.e., a product having a visually identifiable homogeneity by a reduced or even absence of an inhomogeneous drape of the ballistic resistant sheets in the article after moulding). Additionally these sheets and articles should have a good, and preferably improved, ballistic resistance.

 Preferably, each monolayer in the multi - monolayer sail contains the UD oriented reinforcing fibers with the fiber direction in each monolayer being rotate with respect to the fiber direction in an adjacent monolayer. Such a ballistic resistant sail is very suitable for function in compressed or moulded ballistic resistant articles such as panels and particularly curved panels and articles (for example, inserts, helmet, radomes). An alternative manipulation of the ballistic resistant sheet of the embodiments disclosed herein, being a multi - monolayer structure including a core layer formed of at least one, preferably at least two, inaugural monolayer comprised of foremost unidirectionally oriented reinforcing fibers and an elastomeric matrix fabric which is sandwiched between respective face layers, relates to soft ballistic articles, such as bullet - resistant vests. 
 There is continuous drive towards improved ballistic immune articles, including model articles that enables the manufacture of compressed panels or ballistic resistant shape articles with improved mouldability. Improved mouldability means that upon moulding of a ballistic resistant article, especially a curved ballistic resistant article, constitute respective ballistic repellent sheets, a homogeneous product is obtained (i.e., a product having a visually identifiable homogeneity by a decreased or even absence of an inhomogeneous drape of the ballistic resistant sheets in the article after moulding).
