摘要
玻璃钢 (FRP) 是一种以合成树脂为基体材料, 以玻璃纤维以及玻璃纤维制品为增强材料的纤维增强塑料, 它具有强度高、质量轻、保温、绝缘、耐久性好、耐化学性好、尺寸稳定等优点, 其性能的适应范围非常广泛。因此, 在现代工业、国防工业和科学技术等诸多领域中发挥着不可替代的作用。较其他玻璃钢相比, 不饱和聚酯树脂玻璃钢因原材料来源较为广泛、价格相对便宜、成型温度较低、成型工艺较简单、生产成本低等优点, 是国内应用最普遍的玻璃钢产品。【1】
Abstract
Glass fiber reinforced plastics is a kind of fiber reinforced plastics with synthetic resin as the matrix material and glass fiber and glass fiber products as the reinforcing material. It has the advantages of high strength, light weight, heat preservation, insulation, good durability, good chemical resistance, stable size and so on. Therefore, it plays an irreplaceable role in many fields such as modern industry, national defense industry and science and technology. Compared with other FRP, unsaturated polyester resin FRP is the most widely used FRP product in China due to its advantages such as wide source of raw materials, relatively cheap price, low molding temperature, simple molding process and low production cost.

1.1不饱和聚酯树脂概述
不饱和聚酯树脂，一般是由不饱和二元酸二元醇或者饱和二元酸不饱和二元醇缩聚而成的具有酯键和不饱和双键的线型高分子化合物。通常，聚酯化缩聚反应是在190~220℃进行，直至达到预期的酸值(或粘度)，在聚酯化缩聚反应结束后，趁热加入一定量的乙烯基单体，配成粘稠的液体，这样的聚合物溶液称之为不饱和聚酯树脂 。
