HOLLOW ARTICLE MADE OF UHMWPE TAPES

摘要

The disclosure pertains to pipe-like hollow articles made of ultra-high molecular weight polyethylene (UHMWPE) tapes and a thermoplastic and/or thermoplastic elastomer, whereby in the article, the tapes are wound to create the article, whereby the tapes have a tensile strength of greater than 1.5 GPa according to ASTM D882-00, a modulus of greater than 100 GPa according to ASTM D822-00, and a 200/110 uniplanar orientation parameter of at least 3, whereby the main extension direction of at least one tape in the article is in an angle of 20 to 100° with regard to the main extension direction of the article. Further aspects pertain to two processes for manufacturing such an article.

1. A pipe-like hollow article comprising
ultra-high molecular weight polyethylene (UHMWPE) tapes; and a thermoplastic and/or thermoplastic elastomer, wherein
the tapes have a tensile strength of greater than 1.5 GPa according to ASTM D882-00,a modulus of greater than 100 GPa according to ASTM D822-00,a 200/110 uniplanar orientation parameter of at least 3,a main extension direction of at least half of the tapes in the article is in an angle of 20 to 100° with regard to a main extension direction of the article,the at least half of the tapes have a 200/110 uniplanar orientation parallel to the main extension direction of the tapes that are in an angle of 20 to 100° with regard to the main extension direction of the article, anda main extension direction of at least half of overlapping tapes in the article differ from each other.
