Abstract
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 D882-00, 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.
