Description

Technical Field

[0001] The invention relates to the technical field of glass fiber mat manufacturing, in particular to a glass fiber continuous mat laying device. Background Art

[0002] Glass fiber mat is a mesh non-woven fabric interwoven with glass fibers, which can be used to form FRP. Existing glass fiber mats include glass fiber continuous mats interwoven with continuous filament glass fibers and glass fiber chopped mats interwoven with short glass fibers. The short fibers in the glass fiber chopped mat face in all directions, but because the glass fibers are short in length, the FRP made of the glass fiber chopped mat has a certain degree of strength in all directions, but the strength of the FRP molded by the short glass fibers mainly depends on the bonding force between the resin and the short glass fibers, and the strength of the glass fibers themselves has little effect on the overall strength of the FRP mold. The fibers of the glass fiber continuous mat are continuous filament fibers with a long length, which maximizes the use of the strength of the glass fibers. However, the glass fibers are usually laid in one direction, so that the FRP made of the glass fiber continuous mat has a large strength in only one direction, and the strength in other directions is weak, thereby reducing the overall strength of the FRP.
