What Is Chopped Strand Mat

With chopped strand mats as a general rule estimate the resin reinforcement ratio at 2 1 by weight.

What is chopped strand mat. Chopped strand mat csm is a random fiber mat that provides equal strength in all directions and is used in a variety of hand lay up and open mold applications. Chopped strand mat is the least expensive fiberglass and is often used in mold construction or projects where thickness is needed. Chopped strand mat conforms readily and is well suited to use for odd shaped parts. Because the binder dissolves in resin the material.

It easily conforms to moulds and has fast wet out properties. In the case of polyester and vinylester resins an emulsion bound matt is used and in the case of an epoxy resin a powder bound matt would be used. Chopped strand mat is designed to cover a wide range of layup techniques. Chopped strand mat is produced by chopping continuous strand roving into short 1 5 to 3 inch lengths and dispersing the cut fibers randomly over a moving.

It is typically processed using the hand lay up technique where sheets of material are placed on a mold and brushed with resin. Mat is often used as the first layer before the gelcoat in a laminate to prevent print through. Jsc polotsk steklovolokno offers the chopped strand mat with weight 300 450 600 g m2 and width 125 cm csm 300 125 csm 450 125 csm 600 125 to its consumers. Long fiberglass strands laid randomly in a styrene binder.

Available in various lengths and three different weights. Chopped strand mat is a non woven cloth from chopped glass fiber of a regular distribution. Chopped strand mat is most frequently used with polyester resin to quickly build thickness for parts and between layers of fabric for building molds. Use weights per lineal yard to estimate resin requirements.

Chopped strand mat csm is made up of chopped strands of glass fibre laid randomly and held together with a binder or stitching. Chopped stand mat can be chemically or mechanically bound. Chopped strand mat csm is a widely used traditional reinforcement solution. It consists of glass fibers laid randomly across each other and held together by a binder.

Chopped strand mat or csm is a form of reinforcement used in fiberglass. Available online in various quantities and sizes or request our free print catalog. Also called csm chopped strand mat non woven fiberglass mat material is typically used for repair work and laminate build up. Chopped strand mat weight is specified in ounces per square foot.

It can be used alone or in conjunction with fiberglass fabrics or woven roving in larger fabrications. Fabricators generally tear apart chopped strand mat rather than cut it. Fiberglass mat also known as chopped strand mat or csm p fiberglass mat is a non woven material typically used for laminate build up and repair work.
