The main components, characteristics and common different forms of glass fiber
二、What are the common glass fiber forms, do you know?
In the previous articles, we also introduced some basic knowledge of FRP, you can review it if you are interested. FRP is currently widely used. In fact, FRP is simply the abbreviation of glass fiber and resin composite. The often-mentioned glass fibre roll will adopt different forms according to different products, processes and performance requirements of use, so as to achieve different Requirements. Today we will talk about the different forms of common glass fibers.
1. Twistless Roving
Unidirectional roving is further divided into direct roving and ply roving. Direct yarn is a continuous fiber drawn directly from glass melt, also known as single-strand untwisted roving. The plied yarn is the coarse sand made of multiple parallel strands, which is simply the synthesis of multiple strands of direct yarn.
Teach you a little trick, how to quickly distinguish between direct yarn and plied yarn? One strand of yarn is drawn out and shakes quickly. The one that remains is straight yarn, and the one that is dispersed into multiple strands is plied yarn.
2. Bulk yarn
Bulked yarn is made by impacting and disturbing glass fibers with compressed air, so that the fibers in the yarn are separated and the volume is increased, so that it has both the high strength of continuous fibers and the fluffy properties of short fibers.
Plaid is a roving fiber fabric, the warp and weft are interlaced at 90° up and down, also known as woven fabric. The strength of the gingham is mainly in the warp and weft directions.
