摘要： The invention relates to a composite sheet, and a ballistic resistant article, comprising unidirectionally aligned high performance polyethylene (HPPE) fibers and a polymeric resin, wherein said polymeric resin comprises a homopolymer or copolymer of ethylene and wherein said polymeric resin has a density as measured according to ISO1183 of between 930 and 980 kg/m3, and a peak melting temperature of from 115 to 140° C.; and said polymeric resin is present in an amount of from 5 to 25% by weight based on the total weight of the composite sheet. It further relates to a method for manufacturing a composite sheet comprising assembling HPPE fibers to a sheet, applying an aqueous suspension of a polymeric resin to the HPPE fibers, partially drying the aqueous suspension, optionally applying a temperature and/or a pressure treatment to the composite sheet.

摘要： The invention concerns a high performance polyethylene (HPPE) member comprising at least 5 wt-% of a radiopaque component, the HPPE member is biocompatible and the radiopaque component is a particulate at least partially arranged inside a HPPE filament of the HPPE member. Furthermore, the radiopaque component has a particle size of at most 1 μm, preferably the radiopaque component has a particle size of at most 0.5 μm. The invention also concerns a method of making the HPPE member and various medical devices and repair products comprising the HPPE member.
