Abstract:
The invention relates to a multilayered material sheet comprising a consolidated stack of unidirection monolayers of drawn ultra high molecular weight polyolefine. The draw direction of two subsequent monolayers in the stack differs. Moreover the thickness of at least one monolayer does not exceed 50 μm, and the strength of at least one monolayer is comprised between 1.2 GPa and 3 GPa. 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.
Abstract:
Disclosed is a tire-reinforcing steel cord for a radial tire. The tire-reinforcing steel cord has a double layer structure including a first-layer core and a second-layer core provided on the surface of the first-layer core. The first-layer core has an elliptical or rectangular cross section. The tire-reinforcing steel cord can improve processability, fatigue characteristics, and rolling resistance performance of a tire, resulting in improved fuel efficiency. A radial tire using the tire-reinforcing steel cord is also disclosed.
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/1000 C/ES) between the number of olefinic branches per thousand carbon atoms (OB/1000 C) 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:
The invention provides a high-strength rigging and a preparation method thereof. The method at least comprises the following step: preparing a body of the high-strength rigging from an ultra-high molecular weight polyethylene thin film or strip. The high-strength rigging at least comprises the body prepared from the ultra-high molecular weight polyethylene thin film or strip. The invention replaces traditional ultra-high molecular weight polyethylene fibers with the UHMW-PE thin film or strip to prepare the rigging, and the obtained rigging has one or more of the advantages of good structural integrity, simple preparation process, high production efficiency, high strength, high strength utilization ratio, light weight, good flexibility, environmental friendliness and the like.
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:
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.
