    (1) short cut

    Raw silk felt

    The raw glass (sometimes also roving) is cut into 50mm long and randomly spread evenly on the mesh belt. Then the emulsion binder or the powder binder on the spreading agent is then heated to solidify and then cut into chopped strand felt.

    Chopped felt is mainly used in hand paste, continuous plate and die pressing and SMC process.

    The quality requirements for chopped strand felt are as follows: (1) the area quality is uniform along the width direction; (2) the chopped strand is evenly distributed on the felt surface, without the formation of large holes, and the binder distribution is uniform.


    (2) the continuous raw silk formed in the process of drawing, or the continuous raw silk, which is regenerated from the original tube, is laid on the continuous mobile belt with a 8 character shape and is bonded by powder binder.

    Continuous glass fiber felt is continuous in fiber, so its reinforcing effect on composite material is better than that of short cut felt.

    It is mainly used in pultrusion process, RTM method, pressure bag method and glass mat reinforced thermoplastic (GMT) technology.


    (3) surface felt glass steel products usually need to form a resin rich layer, which is usually realized by using alkali glass surface felt.

    This kind of felt is made of alkali glass (c), so it confers chemical resistance, especially acid resistance to FRP. At the same time, because of the thin tapes and the finer diameter of glass fiber, it can absorb more resin to form a resin rich layer, which blocks the texture of glass fiber reinforced materials (such as checkerboard) and plays a surface modification role.


    (4) needle felt or cut into short cuts.

    fibre

    Needle felt and continuous filament needled felt.

    Short cut fiber needled felt is a short cut of glass fiber roving to 50mm, placed on the substrate placed on the conveyor belt at random, and then needled with a barbed pin. The needle will cut short fibers into the bottom, while the crochet will bring some fibers up to form a three-dimensional structure.

    The base material can be a thin fabric of glass fiber or other fibers, which has a sense of fluff.

    Its main uses include thermal insulation, sound insulation materials, lining materials, filter materials, and also in FRP production, but the FRP strength is low and the use range is limited.

    Another kind of continuous needling felt is a three dimensional structure felt which is thrown continuously on the continuous net belt by the wire throwing device of continuous glass precursor, and is formed by needling the needle plate.

    This felt is mainly used for glass fiber reinforced thermoplastic punching sheet production.


    (5) suture felt short cut

    glass fibre

    It can be used to stitch short or long fiber felts from 50mm or 60cm length. The former can replace the traditional binder chopped felt in a number of uses, and the latter will replace the continuous strand felt to a certain extent.

    Their common advantages are that they do not contain binders, avoid contamination in the production process, and have good soaking performance and low price.
