Abstract In this paper, comparisons of the adhesive strengths of two commercially available adhesives, epoxy and cyanoacrylate, on 3D printed plastic materials, Acrylonitrile Styrene Acrylate (ASA) and Nylon 12 Carbon Fiber (NCF) were carried out. The single lap shear test is used to determine the adhesive properties of the specimens with and without post-curing at elevated temperature. A comparison is made with fully printed, non-bonded specimens to give a relative gauge of the performance of the adhesives. It was found that for ASA and NCF, the adhesive strength for cyanoacrylate (CA) is much higher than that of epoxy. ASA and NCF bonded with CA had average failure load of 1810 kN and 2310 kN, respectively, as compared to those bonded with epoxy which had significantly lower failure load of 470 kN and 860 kN, respectively. It was observed that although heat treatment and surface treatment improve the adhesive strength of epoxy with both adherend materials, the improved adhesive strength of epoxy is still observed to be significantly weaker than that of CA.

在接合的 3D 打印聚合物材料上评估结构环氧树脂和氰基丙烯酸酯粘合剂

摘要 本文比较了两种市售粘合剂环氧树脂和氰基丙烯酸酯在 3D 打印塑料材料丙烯腈苯乙烯丙烯酸酯 (ASA) 和尼龙 12 碳纤维 (NCF) 上的粘合强度。单搭接剪切试验用于确定试样在高温下后固化和未固化后的粘合性能。与完全印刷的非粘合试样进行比较,以给出粘合剂性能的相对标准。发现对于 ASA 和 NCF,氰基丙烯酸酯 (CA) 的粘合强度远高于环氧树脂。ASA 和 NCF 与 CA 结合的平均失效载荷分别为 1810 kN 和 2310 kN,而与环氧树脂结合的那些失效载荷分别显着低于 470 kN 和 860 kN。
