High performance needled mat / felt
LIH FENG JIING 's fiberglass needle mat is a mechanically bonded glass fiber insulation blanket of uniform density.
It is manufactured from a well-controlled assortment of long textile glass fibers to ensure uniform mechanical bonding with no additional binders.
The resulting product has excellent insulation efficiency for extended exposure at high temperatures. Also good for sound insulation and filtration applications.
WHAT IS GRP?
Glass-reinforced plastic (GRP) is a composite material or fiber-reinforced plastic made of a plastic reinforced by fine glass fibers. Like graphite-reinforced plastic, the composite material is commonly referred to as fiberglass.
The glass can be in the form of a chopped strand mat (CSM) or a woven fabric.
As with many other composite materials (such as reinforced concrete), the two materials act together, each overcoming the deficits of the other. Whereas the plastic resins are strong in compressive loading and relatively weak in tensile strength, the glass fibers are very strong in tension but tend not to resist compression.
By combining the two materials, GRP becomes a material that resists both compressive and tensile forces well.
The two materials may be used uniformly or the glass may be specifically placed in those portions of the structure that will experience tensile loads.
Glass fiber (or glass fibre) is a material consisting of numerous extremely fine fibers of glass.
Glass fiber when used as a thermal insulating material is specially manufactured with a bonding agent to trap many small air cells, resulting in the characteristically air-filled low-density "glass wool" family of products.
Glass fiber has roughly comparable mechanical properties to other fibers such as polymers and carbon fiber.
Glass fibers are therefore used as a reinforcing agent for many polymer products; to form a very strong and relatively lightweight fiber-reinforced polymer (FRP) composite material called glass-reinforced plastic (GRP), also popularly known as "fiberglass".
Glass Fiber Chemical Compositions Chemical composition variation within a glass type is from differences in the available glass batch raw materials, or in the melting and forming processes, or from different environmental constraints at the manufacturing site.
These compositional fluctuations do not significantly alter the physical or chemical properties of the glass type.
Very tight control is maintained within a given production facility to achieve consistency in the glass composition for production capability and efficiency.
Stitch chopped strand mat is a fabric made by chopping continuous strands into chopped strands of certain length and stitching together the chopped strands. It is compatible with polyester, vinyl ester, phenolic and epoxy resins. This product is widely used in pultrusion, hand lay-up and RTM processes.
The typical end-use applications include FRP boat hulls, laminates, structural shapes and the inner lining of pipes.
Polyester thread instead of binders is used for selvedge binding.
The product has good moldability, good drapability, easy operation, excellent rollout characteristics and effective reinforcement.
It also features good wet-out in resins and high productivity.
The thickness, width, bulk density and length can be specified by customers.
