Abstract

The current design of fire hose couplings is overly simplistic, which forces firefighters to carry multiple hoses of different specifications in emergency situations, thereby increasing the burden of firefighting operations. To address this issue, this study proposes the use of two-dimensional woven high-strength polyester fabric as the reinforcing layer and thermoplastic polyurethane tubing as the inner lining of the hose. Through a heat-press bonding process, high-pressure variable diameter hoses are manufactured, and hoses of different specifications are designed and fabricated. This study explores the composite process parameters of the involved materials and investigates their interfacial bonding performance and failure mechanisms under pressure. The results show that by rationally setting the heat-press bonding process parameters and adjusting the weaving structure of the hose, the interfacial bonding strength and pressure resistance of the fire hose can be effectively enhanced. Experimental tests also reveal the failure mechanisms of gradient-diameter hose materials.

变径设计高压消防水带的制造工艺及其耐压性能研究

目前消防软管接头的设计过于简单，迫使消防员在紧急情况下携带多个不同规格的软管，从而增加了消防作业的负担。为了解决这一问题，本研究提出使用二维编织高强聚酯织物作为增强层，热塑性聚氨酯管作为软管的内衬。通过热压粘接工艺，制造高压变径软管，设计制造不同规格的软管。本研究探讨了相关材料的复合工艺参数，并研究了它们在压力下的界面结合性能和破坏机制。结果表明，合理设置热压粘接工艺参数，调整胶管编织结构，可有效提高消防胶管的界面粘接强度和耐压性能。试验还揭示了梯度直径软管材料的破坏机理。
