The invention relates to a material comprising at least one laminate component containing polymeric fibers wherein the material has a loss tangent of less than 8×10.sup.−3 radians as measured at a frequency chosen from the group of frequencies consisting of 1.8 GHz; 3.9 GHz; 10 GHz; 39.5 GHz; and 72 GHz.

High tenacity, high elongation multi-filament polymeric tapes as well as ballistic resistant fabrics, composites and articles made therefrom. The tapes are fabricated from multi-filament fibers/yarns that are twisted together, bonded together, compressed and flattened.

A variety of textile materials comprising tapes oriented in two oblique orientations relative to the textile's length and width directions, called OFT for Oblique Fibre Textiles, are disclosed. Such OFTs are provided with secondary structural integrity/stability, in addition to primary structural integrity/stability, for improved resistance to formation of openings/gaps. OFTs comprising tapes, particularly Spread Fibre and Highly Drawn Polymeric types, are needed in a number of applications such as ballistic mitigation, composite materials, safety products etc. because they provide improved performance, material properties/functions and aesthetics. Such OFTs can be used either independently or in combination with other textile materials. Different types of OFTs are producible by a novel OFT forming process which is technically unlike weaving and braiding processes.

A material sheet is formed of a woven fabric of polymer tapes, wherein the width of a tape varies less than 2% on average in the longitudinal direction of the tape. Processes for the preparation of the material sheet, and to a ballistic resistant article comprising the material sheet are also provided. A ballistic resistant article which includes the material sheet exhibits excellent antiballistic properties.

The invention relates to a process to make films and tapes from ultrahigh molecular weight polyethylene (UHMWPE) in the solid state. The films and tapes according to the invention have an improved thickness whereby the coefficient of variation of the thickness of the film of at most 6%.

The present invention provides an intermediate material composed of an assembly of overlapping and interlaced tapes, characterized in that at least some of the tapes, preferably all of the tapes, known as veiled tapes, are composed of a series of reinforcing yarns or filaments that extend in a direction parallel to the length of the tape to form a unidirectional sheet that is associated on each of its faces with a nonwoven formed from thermoplastic fibers, said two nonwovens providing said veiled tape with cohesiveness because of their thermoplastic nature, to a production method using said material for producing composite parts, and to the composite parts obtained.

Inflatable airbag for a vehicle which is deployed in the event of an accident involving the vehicle to provide protection for an occupant of the vehicle includes a plurality of ribbons coupled together to define an enclosed, fluid-retaining space and a layer of film laminated on at least one of an outer side of the woven ribbons and an inner side of the ribbons. The ribbons may be made from polypropylene, polyethylene, polyester or polyamide and the layers of film may be made from polyethylene, polyurethane, polyester or polyamide. The ribbons and layers of film may be made of the same or different materials.
