Composite materials were prepared using a thiol-acrylate-epoxy dual-curing system filled with Boron Nitride (BN) agglomerates. The adhesive properties obtained with two different acrylate ratios (r_a) were tested to characterize differences and applicability of final thermosets. The effect of bondline thickness, BN wt% and curing procedure on the adhesive strength was evaluated for both acrylate ratios r_a by means of lap-shear tests. Materials with viscous intermediate (r_a = 0.2) results were observed to have the best performance reaching a maximum of almost 5 kN with 20 wt% of BN. On the other hand, materials with an intermediate gelled network (r_a = 0.5) showed a high accuracy in dimension control but lower values of adhesive strength were obtained. A decrease of adhesive strength with the increase of thickness was found for both r_a, while the increase of BN wt% lead to higher adhesive strength. The beneficial effect of dual-curing processing on the adhesive properties of liquid intermediate materials was also experimentally demonstrated.

使用填充有氮化硼 (BN) 团聚体的硫醇-丙烯酸酯-环氧树脂双重固化系统制备复合材料。测试使用两种不同的丙烯酸酯比率 (r _a )获得的粘合性能，以表征最终热固性材料的差异和适用性。评估了两种丙烯酸酯比率的粘合层厚度、BN 重量百分比和固化程序对粘合强度的影响r_a通过搭接剪切试验。 观察到具有粘性中间体 (r _a = 0.2) 结果的材料具有最佳性能，当 BN 为 20 wt% 时，最大可达近 5 kN。另一方面，具有中间凝胶网络（r _a  = 0.5）的材料在尺寸控制方面表现出高精度，但获得的粘合强度值较低。发现两种 r _a的粘合强度随着厚度的增加而降低，而 BN wt% 的增加导致更高的粘合强度。还通过实验证明了双重固化处理对液体中间材料的粘合性能的有益影响。
