Multiaxial warp knitted fabric, tape 3LF〔E567,0°‖E301,+45°‖E301,-45°〕is a non-crimp reinforcing material with 3-axial and layers structure knitted by polyester yarn, which is widely used in producing wind turbine blades, ship, sports, automobile, aerospace, tanks, pipelines, etc.
Multiaxial warp knitted fabric, tape 3LF〔E567,0°‖E301,+45°‖E301,-45°〕is a non-crimp reinforcing material with 3-axial and layers structure knitted by polyester yarn, which is widely used in producing wind turbine blades, ship, sports, automobile, aerospace, tanks, pipelines, etc. This material is a thick fabric, generally used in the rear part of a blade in the producing process, and the part of finished product is also available for processing and installing. The following introduction will be more detailed:
1 Descriptions of the name of the product
1.1 “3” indicates the amount of the layers,
1.2 “LF” means “Multi-layer fabric”,
1.3 The information in the square bracket describes the layer structure of the fabric, every layer connected by“//”. The correspondent letter “E” to each layer indicates the type of the glass in that layer will be E-glass. Meanwhile, the number of the layer indicates the elemental area and gravity, in unit g/m2, then followed by comma.
The structure type of each layer
——“0º”indicates that the array direction of the yarn parallels to the length direction of the fabric.
——“+45°”indicates that the array direction of the yarn and the across warp lie at an angle of about 45 degrees.
——“-45°”indicates that the array direction of the yarn and the across warp lie at an angle of about -45 degrees.
1.4 The letter “L” in the bracket indicates coil stitching
1.5 “1270”indicates the width of the multi-layer fabric, in the unit of mini meter.
1.6 “6” in the in the bracket indicates the cut will be 6 per inch.
