Abstract:
The invention relates to a steel cord (30) comprising cylindrical layers, said cord including: an inner layer (C1) formed by 3 wires, an intermediate layer (C2) formed by 9 wires helically wound around the inner layer (C1), and an outer layer (C3) formed by 14 wires helically wound around the intermediate layer (C2).
Abstract:
Disclosed is a high traction synthetic rope comprising a braided sheath adhered to a strength member by means of a first synthetic portion and portions of material adhered to the outside surface of the braided sheath by means of a second synthetic portion, where the portions of material are formed of a substance that differs from a substance mainly forming the second synthetic portion and also preferably exhibits greater friction when wet and measured on an iron surface than does the substance mainly forming the second synthetic portion.
Abstract:
The invention relates to a creep-optimized ultrahigh molecular weight polyethylene (UHMWPE) fiber obtained by spinning an UHMWPE comprising olefinic branches (OB) and having an elongational stress (ES), and a ratio ( OB/1000C / ES) between the number of olefinic branches per thousand carbon atoms (OB/1000C) and the elongational stress (ES) of at least 0.2, wherein said UHMWPE fiber when subjected to a load of 600 MPa at a temperature of 70°C, has a creep lifetime of at least 90 hours.
Abstract:
An elongated steel element (12) with a martensite, tempered martensite, bainite or sorbite structure has a polymer coating (16) with a thickness lower than 20 μm immediately upon the elongated steel element (14). The friction coefficient and corrosion resistance are both improved by the polymer coating at a lower cost.
Abstract:
A steel cord (10) adapted for the reinforcement of rubber products, the steel cord comprises a core (12) and a layer of filaments (14) with round cross-sections twisted around the core (12). The core (12) comprises a flat wire at a waveform, which lies in the plane of the flat wire. The wire is obtainable by first crimping a round wire and thereafter flattening the crimped wire. The filaments of the layer do not substantially contact each other to make spaces between each other to insure adequate rubber penetration into the cords. The steel cord has improvements on elongation at break.
Abstract:
The abrasion resistance of organic fiber based ropes and cords is increased by a outer woven cover of tapes of high molecular weight and more preferably ultrahigh molecular weight polyethylene.
Abstract:
The invention relates to a multilayered material sheet comprising a consolidated stack of unidirectional monolayers of drawn polymer. The draw direction of two subsequent monolayers in the stack differs. Moreover the strength to thickness ratio of at least one monolayer is larger than 4.5.10 13 N/m 3 . The invention also relates to a ballistic resistant article comprising the multilayered material sheet and to a process for the preparation of the ballistic resistant article.
