像1,3-二乙炔基苯,1-乙炔基芘,1-乙炔基萘,3-乙炔基菲,4,4′-二乙炔基二苯基甲烷和4,4′-二乙炔基联苯这样的芳基乙炔已经合成,并且评价了适于制造碳—碳复合材料的热固性预聚物的潜在能力。这些材料聚合后,碳产率高及熔融态的易渗透性是它们的主要优点。在7kg/cm~2压力下,碳化已固化的树脂,得碳率高达95%。 Such as 1,3-diethynylbenzene, 1-ethynylpyrene, 1-ethynylnaphthalene, 3-ethynylphenanthrene, 4,4’-diethynyldiphenylmethane and 4,4’-diethynyl Aryl acetylenes such as benzene have been synthesized and the potential of thermosetting prepolymers suitable for making carbon-carbon composites has been evaluated. After polymerization of these materials, high carbon yield and easy permeability in the molten state are their main advantages. Under the pressure of 7kg / cm ~ 2, carbonized cured resin, the carbon rate as high as 95%.
