3D woven textile structural composite material takes into account both rigidity and shock absorption

The University of Surrey has reportedly teamed up with Hopkins University to produce a new material that could be used in future cars. The new material can tolerate intense vibrations, also has a remarkable effect of noise suppression (noise elimination, sound dampening).

Researchers use multilayer 3D woven technology textile structural composites (3D woven technical textile composites) as the fiber material, the arrangement of each layer of material makes the middle layer of the textile structure active, and the external layer of material remains rigid, so that in the case of high rigidity can also achieve good shock absorption effect.

Such material properties are rare in conventional materials, because increased rigidity means less mobility of internal particles, which weakens the effect of shock absorption.On the contrary, while ensuring shock absorption, rigidity will be weakened. This is why many metals have high rigidity but poor shock absorption, and foam has good shock absorption but not high rigidity.

There is no doubt that the researchers' new invention is impressive and will have a great impact on the manufacturing of many products, especially those that need both rigidity and shock absorbency.

Imagine making body sheet metal parts with new materials instead of traditional steel and aluminum, and the cabin interior would be quieter as the vehicle moved. Today, car companies have adopted a large number of sound insulation materials to ensure that passengers are not disturbed by noise and vibration.

However, this needs to sacrifice the overall performance of the vehicle and fuel economy, the introduction of sound insulation material will not only affect the performance of the vehicle, but also reduce the space inside the car. However, the adoption of 3D woven textile structural composites can not only achieve the weight reduction goal of the vehicle, but also improve the interior space. In addition, the material is promising, mainly due to its high temperature resistance.

In the research paper, it said: "in addition to the damping and 13 other mechanical properties, the 3D textile structure material represented the fluidic permeability, thermal transport and high-temperature resistance of the customized fluid, which could provide multiple functions for future studies."
