定义：玻璃纤维缝编毡（以下简称缝编毡），是由按一定方向排列的无捻粗纱或方格布作为基层材料，经短切成一定的长度后，无定向均匀平铺,用有机纤维缝编而成。

Fiberglass stitched mat is made from chopped fiberglass strands or woven roving which is cut into a certain length and randomly dispersed ,laid on a roving matrix then stitched together with organic fibers.

产品特点：

1. 均匀性好，湿拉强度高

2. 兼有机织布方向性及毡的多向性特点

3. 表面孔隙多，浸透好

4. 纤维结构具有可设计性

5. 不易产生位移变形，能保持最佳的力学性能

Even thickness, high wet tensile strength retention

Directional properties and strengths same to woven roving

Enough hollows on surface to make it good permeability

Flexibility to design variety weaving structures

Stable structure required to achieve maximum tensile strength properties

用途：
缝编毡应用于增强不饱和聚酯树脂并适用于拉挤成型、注射成型（RTM）、缠绕成型、手糊成型等玻璃钢成型工艺。如拉挤型材管道、贮罐、风力发电机叶片等制品。

Fiberglass stitched mat is used in unsaturated polyester resin strenthen, primarily in pultrusion, RTM, filament winding and hand lay-up processed. Such as pultruded parts, pipes, storage tanks, wind generator blades and other FRP products.
