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 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:Does anybody know whether carbon fiber grid is the same as carbon fiber mesh?: They are the same product, but just names are different.

Q:What is the function of plaster and steel wire netting in Chinese and foreign wall plastering?: The main objective is to prevent the masonry wall from cracking at the contact of the frame, column and wall (in order to reduce costs, most of the walls are made of glass fiber instead of steel wire mesh). For concrete, block, mortar of different material, its thermal expansion and contraction, with concrete walls, stretching strength of mortar strength and masonry plastering the disagreement rate caused by different degree of tension, in order to prevent the crack, we put different strength materials with steel wire mesh together to form a whole. The expansion rate is uniform, so the use of covered wire mesh to prevent, reduce external wall crack.

Q:Each unit project of alkali resistant gridding cloth should send several groups for inspection.: The inspection length should be less than 3 if the material is used in 20000 ㎡ public buildings, residential, commercial buildings with the same construction, same production manufacturer and same process construction and less than 6 if the area is more than 20000 ㎡.

Q:Mesh cloth and Dacron cloth, which one is better?: I think Dacron is better. If it is light wall, and if allowed, you can also use wallpaper to cover the spots.

Q:The difference between glass fiber and plastic fiber screen: Glass filter and PP filter (or other chemical compound) in glass filter just rely on the barrier (collision interception and sieve effect) is the chemical fiber, electrostatic adsorption (and not completely reliable test of electrostatic adsorption accounted for a large).

Q:A brief introduction to glass cloth of glass fiber cloth: The other quality requirements are as follows: the fabric selvedge uniform, flat, smooth cloth is sheetlike, no stains, fluff, creases and wrinkles; the warp and weft density, weight, width and length are consistent with the standard; the paper core winding in solid, winding the resin fast in order; good permeability; the fabric made of laminated material of dry, wet mechanical strength shall meet the requirements.The paving composites are characterized by low interlaminar shear strength, poor compressive strength and fatigue strength. (1) chopped strand glass raw silk (sometimes with roving) cut into 50mm long, but it will be randomly evenly Chen on the mesh belt, then put on powder or emulsion binder spreading agent bonded into CSM by heating after curing. Short cut felt is mainly used for hand finishing, continuous plate making and die pressing and SMC process. The quality of CSM requirements are as follows: uniformly along the width direction of the quality area; the chopped strand mat surface in uniform distribution, no hole formation, binder distribution; with moderate strength, excellent dry mat; resin infiltration and permeability.

Q:The using age limit of alkali-resistant mesh: Poor mesh two months, it is mainly glass fiber yarn made by the recycled glass clay pot. The alkali mesh coated with emulsion can be used for 25 years. Alkali resistance for 50 years

Q:How to fill in the sample size of glass fiber gridding cloth?: The weight of per unit area, the unit is g/c㎡, such as: 450 g/c㎡

Q:does the anti-cracking net between the different matrixof the interior wall plastering can use the glass?fiber alkali resistant mesh? the steel mesh are hanging between the contacts.: Interior finishing layer is generally painted coat, the coat finishing consturction anti-crack net is alkali resistant glass?fiber net, and the veneer of the facing brick consturction anti-crack net is galvanized steel wire netting.due to the consideration of the safety of the engineering and the wall anti-crack net use, the anti-crack net is using the glass?fiber mesh.
