Picking the right fiberglass cloth is very important for your job.There are three types to choose.
1.Woven cloth :
Woven cloth is any textile formed by weaving. Woven fabrics are often created on a loom, and made of many threads woven on a warp and a weft. Technically, a woven fabric is any fabric made by interlacing two or more threads at right angles to one another.
Woven fabrics only stretch diagonally on the bias directions (between the warp and weft directions), unless the threads used are elastic. Woven fabric cloth usually frays at the edges, unless techniques are used to counter it, such as the use of pinking shears or hemming.Fabrics that are woven do not stretch as easily as knitted fabrics, which can make them advantageous for many uses.
2. Chopped strand mat （CSM）
Chopped strand mat or CSM is a form of reinforcement used in fiberglass. It consists of glass fibers laid randomly across each other and held together by a binder.
It is typically processed using the hand lay-up technique, where sheets of material are placed on a mold and brushed with resin. Because the binder dissolves in resin, the material easily conforms to different shapes when wetted out. After the resin cures, the hardened product can be taken from the mold and finished.
Using chopped strand mat gives the fiberglass isotropic in-plane material properties.
3. Biaxial cloth
Biaxial fiberglass is a type of non-woven fiberglass fabric. Instead of a conventional weave pattern, biaxial cloths two layers lie at a 45-degree fiber angle to each other. The two layers are stitched together with sturdy polyester yarn.
