深水静压环境中夹芯结构PUEPM芯材蠕变特性实验研究
Experimental Study on Creep Characteristics of Sandwich PUEPM Core Under Static Pressure of Deep Water Environment
摘要
Abstract
According to the elasticity theory, comparing the core material mechanical states in the sleeve under static pressure and the core mechanical states in the sandwich structure under deep water static pressure environment, the bushing test method adapted to study the creep characteristics of vis-coelastic core materials was presented. The quasi-static compression and bushing compression creep tests for three different microspheres-reinforced polyurethane-modified epoxy resin sound absorption materials (PUEPM) were carried out, the creep behavior of the core materials was obtained. The results show that the delaminated PUEPM core with low content glass microsphere and high content chopped fiber has preferable creep performance. The PUEPM core with higher content glass micro-sphere has higher resilience performance. The PUEPM core of type B has better comprehensive mechanical properties.关键词
