BALLISTIC RESISTANT ARTICLES COMPRISING ELONGATE BODIES

摘要

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.
