WHAT ARE THE COMMON FIBERGLASS FORMS, DO YOU KNOW?

What are the common fiberglass forms, do you know?

It is often said that fiberglass will adopt different forms according to different products, processes and performance requirements of use, so as to achieve different uses.

Today we will talk about the different forms of common glass fibers.

1. Twistless Roving

Untwisted roving is further divided into direct untwisted roving and plied untwisted roving. Direct yarn is a continuous fiber drawn directly from glass melt, also known as single-strand untwisted roving. The plied yarn is a 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.

Bulk yarn

2. Bulk yarn

Bulked yarn is made by impacting and perturbing 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 bulkiness of short fibers.

Plain weave fabric

3. Plain weave fabric

Gingham is a roving plain weave 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.

Axial fabric

4. Axial fabric

Axial fabric is made by weaving glass fiber direct untwisted roving on a multi-axial braiding machine. The more common angles are 0 °, 90 °, 45 ° , -45 ° , which are divided into unidirectional cloth, biaxial cloth, triaxial cloth and quadriaxial cloth according to the number of layers.

Fiberglass mat

5. Fiberglass mat

Fiberglass mats are collectively referred to as felts, which are sheet-like products made of continuous strands or chopped strands that are non-directionally bound together by chemical binders or mechanical action . Felts are further divided into chopped strand mats, stitched mats, composite mats, continuous mats, surface mats, etc. Main applications: pultrusion, winding, molding, RTM, vacuum induction , GMT , etc.

Chopped strands

6. Chopped strands

The fiberglass yarn is chopped into strands of a certain length. Main applications: wet chopped (reinforced gypsum, wet thin felt), B MC , etc.

Grinded chopped fibers

7. Grinded chopped fibers

It is produced by grinding chopped fibers in a hammer mill or ball mill. It can be used as a filler to improve resin surface phenomenon and reduce resin shrinkage.

The above are several common fiberglass forms introduced this time. After reading these forms of glass fiber, I believe that our understanding of it will go further.

Nowadays, fiberglass is currently the most widely used reinforcement material, and its application is mature and extensive, and there are many forms. On this basis, it is easier to understand the fields of application and combination materials.
