Good dimensional stability

熱固性樹酯基體在加工過程受熱作用發(fā)生交聯(lián)形成體型網(wǎng)狀結(jié)構(gòu)，其制品在常態(tài)下尺寸穩(wěn)定好，成型之后發(fā)生的后收縮性也小。制品在長時間的連續(xù)載荷作用下其形狀和尺寸變化極小，即蠕變性小。其蠕變性能取決于載荷的大小，溫度高低和加載時間的長短諸因素。在固定的載荷和溫度條件下，長時間加載后熱固性塑料的蠕變量要比熱塑性塑料小得多。

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.

優(yōu)越的耐熱、耐高溫特性

Superior heat and high temperature resistance characteristics

熱固性樹酯基復(fù)合材料固化后再也不能軟化，其制品耐熱性相當(dāng)穩(wěn)定，用1.86MPa的載荷測定，一般其熱變形溫度在150～260℃內(nèi)，而纖維增強(qiáng)的熱固性塑料屬于優(yōu)良的絕熱材料，其熱導(dǎo)率一般為0.35～0.47W/（m.K），只有金屬的1/1001/1000，可用作良好的隔熱才料和瞬間耐高溫材料，材料的熱變形溫度可達(dá)350℃，可用作常溫和高溫結(jié)構(gòu)材料。玻纖/酚醛是 發(fā)動機(jī)優(yōu)良的絕熱材料。

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.

電性能優(yōu)良

Excellent electrical performance

復(fù)合材料是優(yōu)良的電絕緣材料，若以云母為填料制得的制品其電性能更為優(yōu)異，可用來制造耐電弧性、耐電壓、感應(yīng)電性優(yōu)越的特殊零部件。由于復(fù)合材料具備優(yōu)良的電性能，其制品不存在電化學(xué)腐蝕和雜散電流腐蝕，可廣泛用于制造儀表、電動機(jī)及電器中的絕緣零部件，以提高電器設(shè)備的可靠性并延長其使用壽命。此外，制品在高頻作用下良好的介電性能和微波透過性，已用于制造多種雷達(dá)罩等高頻絕緣產(chǎn)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.

良好的耐腐蝕性

Good corrosion resistance

樹酯基復(fù)合材料與普通鋼的電化學(xué)腐蝕機(jī)理不同，它不導(dǎo)電，在電介質(zhì)溶液中不會溶解出離子，因而對大氣、水和一般濃度的酸、堿、鹽等介質(zhì)具有良好的化學(xué)穩(wěn)定性，特別是在非氧化性強(qiáng)酸和相當(dāng)廣泛的ph值范圍內(nèi)的介質(zhì)中都具有良好的穩(wěn)定性。因此，目前廣泛用于制造耐腐蝕制品，以用于不銹鋼對付不了的某些介質(zhì)（如鹽酸、二氧化碳、稀硫酸、次氯酸鈉和等）的腐蝕，發(fā)揮了良好的作用。

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.
