Abstract
Snap-lock fasteners are very simple for locking two parts. However, because their configuration is complex, snap-lock fasteners are usually made of polymer materials. This implies that the material is usually weak. In this study, we propose a novel snap-lock fastener printed using a 3D printer that prints continuous fiber composites. The novel fastener designed in this study can be easily attached to and detached from fastened parts. Based on the tensile test results, continuous glass fibers were placed at the elastic hinges to strengthen the weak elastic hinges. The reinforced snap-lock specimens were tested under tensile loading. Therefore, the novel snap-lock fastener with continuous glass fiber was able to bear 1.7 times higher load than that without continuous glass fibers.
