Product Description:

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

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:If fiberglass mesh bent, how to straighten it up?
First, from the perspective of raw material, it can be divided into the platinum pot and clay pot. Generally the softness and hardness of clay pot products is difficult to control, because clay pot products are generally coated with urea-formaldehyde resin adhesive, while platinum pot products are coated with latex, so its quality is easy to be controlled. Clay pot products only have two states, namely,hard and soft. One is hard, when the product is slightly positioned, but texture is a little brittle, has a poor pulling resistance and easily gets broken off. The other is soft, such products have relatively greater resistance, but are not positioned, so as for the clay pots coated with urea-formaldehyde resin adhesive, their hardness or softness and positioning are mutually contradictory. That is, hard product has better positioning, but possess a smaller tensile force, while soft product has poor positioning, but better tensile force . But as for platinum pot coated emulsion products, their hardness and softness is easy to be controlled, but has to stay within a certain range, the extreme of either is not conducive to construction. To ensure the positioning, the product's hardness and softness in certain range is adjustable, if too hard, the hair nets would be very bad to live with mortar, because a hard product itself has a certain tension, it is difficult to control the mesh. Not soft products in the construction could not be hooked on, so the hardness and softness must be moderate, products with good positioning are easy to be constructed. Just take a trowel with mortar wipe live on the line, if the positioning is not good, when wiping with a trowel, the line will move back and forth, which will affect the overall effectiveness of the insulation and construction.
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:How to produce mesh?
With medium-alkaline or non-alkaline glass fiber yarn as raw materials and woven fiberglass mesh as base material, external wall thermal insulation mesh is a new alkali resistant product after coated with acrylic copolymer solution. With medium-alkaline or non-alkaline fiberglass mesh as base materials, internal wall thermal insulation alkali resistant fiberglass mesh is formed by being coated with modified acrylate copolymer adhesive solution.
Q:Function of fiber net in building plastering
The wall hanging wire mesh is used in the front wall plastering frame structure brick masonry and frame column and wall contact vertical slot and the top surface of the horizontal seam, a layout, the main purpose is to prevent the masonry wall and frame column and wall contact cracking (in order to reduce the cost of inner wall is mostly used for glass fiber mesh instead of wire net). 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:What functions does fiberglass wall mesh have ?
Fiberglass mesh uses glass fiber woven fabric as the substrate, and is immersed and coated by polymer emulsion resistance. Thus having good alkali resistance, flexibility and high warp-wise and weft tensile strength, it can be widely used in building internal and external wall insulation, waterproof, cracking and so on. Fiberglass mesh is mainly based on alkali-resistant fiberglass mesh, it uses the C or E-glass fiber yarn (main component is silicate which has good chemical stability) , twisted by special organizational structure-- leno weave, and then experiences high temperature heat processed through anti-alkaline, and enhancers.
Q:How to combine fiberglass mesh and interior wall?
They are combined by cracking resistant mortar.
Q:Can glass fiber grid cloth be fiberglass reinforcing material?
Glass reinforced plastics refers to using glass fiber to reinforce polyester, epoxy resin and phenolic resin. Glass reinforced plastics, also called glass fiber reinforced plastic fiberglass is reinforced plastics made of glass fiber or its products.
Q:The house is hollowing in some parts at present. If you want to install mesh, is there a need to repair the hollowing parts?
The process of the hollowing. When the hollowing appears, do not be afraid because there is no any effect if it is handled properly. First, cut out the hollowing parts with a cutter and adjust the depth of the knife edge which is generally well advised to 15mm. The cutting area should be actually bigger than the hollowing parts. You should not use the chisel blindly because it may make the hollowing parts become much bigger. Only after cutting can we used a chisel to remove the surface layer within the range of hollowing. In primary processing, the base must be cleaned and moistened with water with the 1: 2.5 cement mortar as bottom. 3. The surface of the cement mortar can be patched twice and wiped with pressure so as to prevent the cracking of the combination of the old and new from appearing again. If it is the concrete base, it should be brushed with the concrete interfacial agent, otherwise the hollowing will appear again.
Q:Which is good, glass fiber composite or carbon fiber?
Of course, carbon fiber composite properties of high ah, but the price is also high.
