Abstract: The present invention relates to hybrid sheet comprising: i) high-performance polyethylene (HPPE) fibers; ii) a polymeric resin, wherein the polymeric resin is selected from a group consisting of a homopolymer of ethylene, a homopolymer of propylene, a copolymer of ethylene, and a copolymer of propylene and wherein said polymeric resin has a density as measured according to ISO1183-2004 in the range from 860 to 970 kg/m3, a peak melting temperature in the range from 40 to 140° C. and a heat of fusion of at least 5 J/g; iii) non-polymeric fibers; and iv) optionally, a matrix material. Furthermore, the present invention relates to a process to manufacture the hybrid sheet and to the use of the hybrid sheet in various fields, such as in automotive field, in aerospace field, in sports equipment, in marine field, in military field; and in wind and renewable energy field.

Abstract: The invention relates to a method for manufacturing a composite sheet comprising high performance polyethylene fibres and a polymeric resin comprising the steps of assembling HPPE fibres to a sheet, applying an aqueous suspension of a polymeric resin to the HPPE fibres, partially drying the aqueous suspension, optionally applying a temperature and/or a pressure treatment to the composite sheet wherein the polymeric resin is a homopolymer or copolymer of ethylene and/or propylene. The invention further relates to composite sheets obtainable by said method and articles comprising the composite sheet such as helmets, radomes or a tarpaulins.
