The invention pertains to a ballistic-resistant moulded article comprising a compressed stack of sheets comprising reinforcing elongate bodies, wherein at least some of the elongate bodies are polyethylene elongate bodies which have a weight average molecular weight of at least 100 000 gram/mole and a Mw/Mn ratio of at most 6. The polyethylene elongate bodies preferably have a weight average. molecular weight of at least 300 000 gram/mole, in particular at least 400 000 gram/mole, still more in particular at least 500 000 gram/mole. When polyethylene elongate bodies are tapes, they preferably have a 200/110 uniplanar orientation parameter of at least 3. Where the elongate bodies are fibres, they preferably have a 020 uniplanar orientation parameter of at most 55. A method for manufacturing the ballistic-resistant moulded article is also claimed.

L'invention porte sur un article moulé résistant aux projectiles comprenant un empilement comprimé de feuilles contenant des corps allongés de renfort, au moins certains des corps allongés étant des corps allongés en polyéthylène qui ont une masse moléculaire moyenne en masse d'au moins 100 000 grammes/mole et un rapport Mw/Mn d'au plus 6. Les corps allongés en polyéthylène ont de préférence une masse moléculaire moyenne en masse d'au moins 300 000 grammes/mole, en particulier d'au moins 400 000 grammes/mole, et encore plus particulièrement d'au moins 500 000 grammes/mole. Lorsque les corps allongés en polyéthylène sont des bandes, ils ont de préférence un paramètre d'orientation uniplanaire 200/110 d'au moins 3. Lorsque les corps allongés sont des fibres, ils ont de préférence un paramètre d'orientation uniplanaire 020 d'au plus 55. L'invention porte également sur un procédé pour fabriquer l'article moulé résistant aux projectiles.
