CORE MAT
PRODUCT DESCRIPTION
CORE MAT is a stratified reinforcing glass fiber fabric composed by 5 layers. 2 exterior layers of random mat, 1 layer of woven roving and 2 layers of synthetic fibers. The main application is for RTM and RTM Light parts where mechanical performance is a must.

CONSTRUCTION
CORE MAT has been manufactured by stitch bonding technology. The 5 layers are arranged as follows:
Layer 1: Random glass fiber mat
Layer 2: Synthetic Web
Layer 3: Woven roving
Layer 4: Synthetic Web
Layer 5: Random glass fiber mat

The layers 2 and 4 are made by a synthetic material (polypropylene)and the main purpose of these layers is to allow the resin flow and provide compressibility to the reinforcement.

STYLES
The standard materials are the ones in the following list, but other designs are also available according to customer needs

How to understand CORE MAT description:

Example:
250BWR500B250

Q:Is glass fiber gridding cloth belong to metal gridding cloth?: It should not be that.

Q:Glass fiber gridding cloth is easy to be broken after being glued.: It depends on the glues.

Q:What is the base material of fiberglass mesh?: Of course, its base material is glass fiber. You said it was rough, probably the reason wass that in the process of producing glass fiber, immature technology caused broken filament, and after treatment, the adhesive?sticker, alkali-resistant glue or weather-proof glue was unevenly attached on the surface. So it looks rough. This is just the unqualified product in production process, and there isn't any counterfeit product. These product are not beautiful and their strength will be lower than that of qualified products. (The intensity of different mesh will have different degrees of decline: generally, the largest mesh opening is, the greater will the strength decline; conversely, the smaller mesh opening is, the smaller will the strength decline).

Q:Is glass fiber gridding cloth or finer wire mesh used before painting walls? What's the difference between them?: If the cracks are too more, them gridding cloth is better to paste and batch apply putty. Or common bonding is ok. However, steel wire mesh is not to use hen batch applying putty. Moreover, if leveling cement mortar, then steel wire mesh can be used.

Q:What's the gridding cloth? What's the application of them?: With glass fiber woven fabric as base material, gridding cloth is processed with high alkali emulsion. GRC products are featured by high strength, lasting alkali resistance. Cement and concrete products, GRC wallboard and GRC components.

Q:What is the grid fabric like? What are their uses?: Popular point is that the building used to prevent thermal insulation materials

Q:How to produce mesh?: Firstly but yarn, and warp weaving glue.

Q:I am a worker using glass silk to weave mesh. What harm does long-term work do to body?: Glass fiber itself is not toxic, but the woven mesh trimming process produces glass dust. If long-term toleration, you will have lung problems. You should wear a dust mask in dust wroking environment such as dip and lime. If necessary, you should also wear gloves.

Q:external wall thermal insulation is using 10BJ2-11, external wall F2-1M-3. How to calculate the amount of alkali-resistant glass?fiber mesh.: Mesh only laying the internal and external corners is ok.

Q:What is the construction method of external wall thermal insulation mesh: 1, It needs specially-assigned person to compound the polymer mortar in order to ensure the quality of stirring. 2, open the bung by contrarotate, and then remix the adhesive with a stirrer or other tools to prevent the parting phenomenon of binder, you should stir moderately, so as not to render quality problems. 3, polymer mortar mix ratio: KL Binder: 425# sulphate aluminium cement: Sand (with a 18 mesh screen): 1: 1.88: 3.25 (weight ratio). 4, After cement and sand are measured by the bucket, pour into iron gray groove, and then mix evenly. And pour into binder in mix proportion, stirring evenly into gruel to prevent dissociation. It can appropriately add water due to the workability. 5, water is the concrete water. 6, polymer mortar should be used with the distribution, the deployed polymer mortar preferably is better to run out within one hour. Polymer mortar should be placed in a cool place to avoid sun exposure.
