Design and mechanical analysis of shear thickening fluid/polyurethane composite sandwich
نویسندگان
چکیده
In this paper, high density rigid polyurethane foam is used as sandwich skeleton and shear thickening fluid material core. A fluid/polyurethane structure with light impact resistance was designed fabricated. High strain rate test carried out. It found that STF-2/PU reached the peak load of 4978N in 13 ms after receiving 20 J energy, energy absorption ratio 43%. The honeycomb prepared by secondary foaming process has stable can effectively absorb to achieve good protection effect.

experimental bending analysis of strip sandwich and laminated composite plates
there exist simple theories to predict the strain of sandwich structures under a bending load and specific support conditions. although theoretical predictions are highly effective, but the role of testing in validation of these theories and their progress is undeniable. the main goal of the present paper is to prepare a test instruction in order to minimize the error of data acquisition and th...
متن کاملGeometric design and mechanical properties of cylindrical foldcore sandwich structures
Sandwich structures with foldcores are regarded as a promising alternative to conventional honeycomb sandwich structures as lightweight structural materials. One of the proposed applications of foldcore sandwich structures is on the aircraft fuselage and the interstage of a rocket. While flat foldcore sandwich structures have been intensively studied in the literature, there lacks a general des...
متن کاملShear-Thickening Fluid
Shear-Thickening Fluids (STFs) are a special Non-Newtonian Fluid that act like a solid when they experience a force. A simple example of this is a mixture of cornstarch and water. In this experiment, I text this mixture’s STF properties by using a ball drop to simulate an impact. By varying the ball drop height (and thus the force upon impact), and observing the bounce height, I determined wher...
متن کاملShear thickening of cornstarch suspensions
We study the rheology of cornstarch suspensions, a non – Brownian particle system that exhibits discontinuous shear thickening. Using Magnetic Resonance Imaging (MRI), the local properties of the flow are obtained by the determination of local velocity profiles and concentrations in a Couette cell. For low rotational rates, we observe shear localization characteristic of yield stress fluids. Wh...
