摘要:
A geogrid using fiber-reinforced polymeric strips and its producing method are disclosed. The geogrid of a lattice shape includes plural longitudinal fiber-reinforced polymeric strips longitudinally arranged in parallel at regular intervals and formed by reinforcing fiber in a thermoplastic polymer resin, and plural lateral fiber-reinforced polymer strip laterally arranged in parallel at regular intervals and formed by reinforcing fiber in a thermoplastic polymer resin. Each longitudinal fiber-reinforced polymer strip has at lease one first contact point crossed with the lateral fiber-reinforced polymer strip on the upper surface and at least one second contact point crossed with the lateral fiber-reinforced polymer strips on the lower surface. The contact points are fixed by welding the longitudinal and lateral fiber-reinforced polymer strips. The geogrid is excellent in installation capacity, frictional feature and shape stabilisation and shows high tensile strength and low tensile strain and low creep deformation.

The present invention concerns weaving. In particular, it is a woven material produced using tape-like warp and tape-like weft through the employment of a rotary type shedding device which also functions as a direct specific-weave patterning device and a pick guiding device. The material according to the invention has a constructional constitution of at least some of the warp and weft that is non-homogenous. The invention also relates to a weaving device for producing woven material with tape-like warp and weft, comprising a rotary device, which is capable of producing more than one fabric simultaneously.
摘要:
A method and apparatus for supplying twist free flat warp containing a plurality of carbon fibers to a plurality of wefts in a weaving loom, wherein the warp is transversely removed from a plurality of bobbins and twisted along a longitudinal travelling direction of the warps so that flat surfaces of individual flat warps are oriented at a right angle to an arranged direction. The plurality of flat warps are reeded to a desired density in relation to the arranged direction. The warps are then twisted along the longitudinal travelling direction so that the flat surfaces of the individual flat warps are oriented to the arranged direction.
摘要:
Formable twistless woven precursor fabrics, especially in satin or basket weave, made from flat tape of fiber reinforced thermoplastics on a power driven loom. The weft tape is supplied from a rotatable package that is driven in synchronism with the feeding mechanism and a finite tension on the tape is maintained.
