Provided is a high performance anti-spall laminate article comprising a bi- layer polymeric composite. The bi-layer composite includes a polymeric sheet and a poly(ethylene terephthalate) (PET) film laminated to each other. The PET film has a tensile modulus of about 600,000 psi or higher in both the machine direction (MD) and the transverse direction (TD), a shock brittleness index of about 55 Joules or higher in the machine direction and about 25 joules or higher in the transverse direction, and a percent elongation at break (EOB) of about 110-160 in the machine direction and about 60-110 in the transverse direction.
La présente invention concerne un produit stratifié anti-éclats haute performance comprenant un composite polymère bicouche. Le composite bicouche comprend une feuille polymère et un film de polyéthylène téréphtalate (PET) stratifiés lun sur lautre. Le film PET présente un module de traction d'environ 600000 psi (~4,1.109 Pa), ou plus, dans les deux directions, machine (MD) et transversale (TD), un indice de fragilité aux chocs d'environ 55 joules ou plus dans la direction machine et d'environ 25 joules ou plus dans la direction transversale, et un pourcentage d'allongement à la rupture (EOB) d'environ 110 à 160 dans la direction machine et d'environ 60 à 110 dans la direction transversale.
