A brief introduction to glass cloth of glass fiber cloth
Glass fabric, glass fiber braid, glass clothGlass, Fiber, Cloth, or, Fabric, and, Tape, glass roving, glass fiber, diameter from 12~23 M. Roving the number from 150 to 9600 (Tex). Roving can be directly used for some composite molding methods, such as winding, pultrusion process, because of its uniform tension, can also be woven roving fabric, in certain applications will also be further chopped rovings.
The continuous strand felt is formed from the glass filament in the drawing process or from the original filament cylinder, and the continuous filament is 8 in shape. It is deposited on the continuous moving mesh belt and bonded by powder binder. The fiber in continuous glass fiber felt is continuous, so its strengthening effect on composites is shorter and the felt is good. Mainly used in pultrusion, RTM, pressure bag and glass mat reinforced thermoplastics (GMT) and other processes.
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.
