Good dimensional stability

热固性树酯基体在加工过程受热作用发生交联形成体型网状结构，其制品在常态下尺寸稳定好，成型之后发生的后收缩性也小。制品在长时间的连续载荷作用下其形状和尺寸变化极小，即蠕变性小。其蠕变性能取决于载荷的大小，温度高低和加载时间的长短诸因素。在固定的载荷和温度条件下，长时间加载后热固性塑料的蠕变量要比热塑性塑料小得多。

The thermosetting resin matrix undergoes cross-linking during the processing process to form a network like structure. The product has good dimensional stability under normal conditions, and the post shrinkage after molding is also small. The shape and size of the product undergo minimal changes under long-term continuous loading, resulting in minimal creep. Its creep performance depends on factors such as the size of the load, temperature, and loading time. Under fixed load and temperature conditions, the creep of thermosetting plastics after long-term loading is much smaller than that of thermoplastic plastics.

优越的耐热、耐高温特性

Superior heat and high temperature resistance characteristics

热固性树酯基复合材料固化后再也不能软化，其制品耐热性相当稳定，用1.86MPa的载荷测定，一般其热变形温度在150～260℃内，而纤维增强的热固性塑料属于优良的绝热材料，其热导率一般为0.35～0.47W/（m.K），只有金属的1/1001/1000，可用作良好的隔热才料和瞬间耐高温材料，材料的热变形温度可达350℃，可用作常温和高温结构材料。玻纤/酚醛是 发动机优良的绝热材料。

After curing, thermosetting resin based composite materials can no longer soften, and their products have relatively stable heat resistance. When measured under a load of 1.86MPa, their thermal deformation temperature is generally within 150~260 ℃. Fiber reinforced thermosetting plastics are excellent insulation materials, with thermal conductivity generally ranging from 0.35 to 0.47W/(m.K). Only 1/100 to 1/1000 of metals can be used as good insulation materials and instant high-temperature resistant materials, The thermal deformation temperature of the material can reach 350 ℃, which can be used as both room temperature and high temperature structural materials. Glass fiber/phenolic resin is an excellent insulation material for engines.

电性能优良

Excellent electrical performance

复合材料是优良的电绝缘材料，若以云母为填料制得的制品其电性能更为优异，可用来制造耐电弧性、耐电压、感应电性优越的特殊零部件。由于复合材料具备优良的电性能，其制品不存在电化学腐蚀和杂散电流腐蚀，可广泛用于制造仪表、电动机及电器中的绝缘零部件，以提高电器设备的可靠性并延长其使用寿命。此外，制品在高频作用下良好的介电性能和微波透过性，已用于制造多种雷达罩等高频绝缘产品。

Composite materials are excellent electrical insulation materials. Products made with mica as filler have better electrical properties and can be used to manufacture special components with superior arc resistance, voltage resistance, and induction resistance. Due to the excellent electrical properties of composite materials, their products are free from electrochemical corrosion and stray current corrosion, and can be widely used in the manufacturing of insulation components in instruments, motors, and electrical appliances to improve the reliability of electrical equipment and extend its service life. In addition, the products have good dielectric properties and microwave transmittance under high-frequency conditions, and have been used to manufacture various high-frequency insulation products such as radar hoods.

良好的耐腐蚀性

Good corrosion resistance

树酯基复合材料与普通钢的电化学腐蚀机理不同，它不导电，在电介质溶液中不会溶解出离子，因而对大气、水和一般浓度的酸、碱、盐等介质具有良好的化学稳定性，特别是在非氧化性强酸和相当广泛的ph值范围内的介质中都具有良好的稳定性。因此，目前广泛用于制造耐腐蚀制品，以用于不锈钢对付不了的某些介质（如盐酸、二氧化碳、稀硫酸、次氯酸钠和等）的腐蚀，发挥了良好的作用。

The electrochemical corrosion mechanism of resin based composite materials is different from that of ordinary steel. It is non-conductive and does not dissolve ions in dielectric solutions. Therefore, it has good chemical stability against atmospheric, water, and general concentrations of acids, bases, salts, and other media, especially in non oxidizing strong acids and a wide range of pH values. Therefore, it is widely used to manufacture corrosion-resistant products for corrosion of certain media (such as hydrochloric acid, carbon dioxide, dilute sulfuric acid, Sodium hypochlorite, etc.) that stainless steel cannot cope with, and has played a good role.
