摘　　要：以四种不同的油浆为原料,在酸性催化剂存在下,与对苯二甲醇反应,得到四种COPNA树脂。以COPNA树脂、酚醛、环氧树脂为基体,与炭纤维复合,通过模压成型,得到四种不同基体的复合材料。考察并比较了COPNA树脂的软化点、残炭、β树脂含量等黏结性参数以及树脂/炭纤维复合材料的抗冲击强度和层间剪切强度。从大庆油浆得到的COPNA树脂为基体的炭纤维复合材料,表现出的力学性能优于酚醛、环氧树脂,间接证明了COPNA树脂与炭纤维有较强的亲和性。这为COPNA树脂的应用提供了一个很好的方向。Four different condensed polynuclear aromatic (COPNA) resins were obtained by reacting different heavy residue oils with 1,4-benzenedimethanol and p-toluenesulfonic acid. Their adhesive related properties including softening-point, carbon residue, beta resin content, were tested. Four different composites using them as binders were made by molding different resins with carbon fibers and their mechanical properties were tested. Results showed that the mechanical properties of the composites from COPNA resins from Daqing slurry are better than those from conventional bakelite and epoxy resin. This is ascribed to their good adhesion to the carbon fibers.
