High practicality of dry goods composite materials

Composite materials are the products of two or more materials with different properties and performances.

In nature, many substances can be regarded as composite materials.

In production and life, people have created a large number of composite materials, ranging from tables, chairs and benches at home, to airplanes and rockets.

In the aerospace field, composite materials are used to manufacture aircraft wings, front fuselages, satellite antennas and supporting structures, engine housings, and structural parts of space shuttles due to their good thermal stability, high specific strength and specific rigidity.

In the automotive industry, composite materials have special vibration damping characteristics, which can reduce vibration and noise, have good fatigue resistance, are easy to repair after damage, and are easy to form as a whole.

In the fields of chemical, textile and machinery manufacturing, carbon fiber and resin matrix composite materials with good corrosion resistance can be used to manufacture chemical equipment, textile machines, paper machines, photocopiers, high-speed machine tools, and precision instruments

It is conceivable that if there is no composite material, the world should not be what it is now

Composite material tensile deformation measurement

The performance of the composite material is different from its component materials.

The study of the mechanical properties of composite materials is critical to the design and selection of materials
.
A university laboratory designed a tensile experiment of composite materials, and used Xintuo 3D XTDIC three-dimensional full-field strain measurement and analysis system to conduct image acquisition and data analysis of the experimental process, aiming to study the tensile force of the composite material sample The resulting deformation, so as to analyze its mechanical properties
.

When the tensile testing machine starts to work, the XTDIC system synchronously collects images until the composite material specimen breaks, stops and completes the collection, and calculates and analyzes the collected data
.

Composite materials have excellent performance and high practicability.
Without composite materials, the world would lose a lot of convenience and comfort
.
In addition, the mechanical properties of composite materials have its complexity and particularity.
It is necessary to express the mechanical properties of composite materials with data in order to be better used in various fields of production and manufacturing
.

In this experiment, the non-contact Xintuo 3D XTDIC 3D full-field strain measurement and analysis system was used to perform full-field measurement on the sample.
The strain and deformation of the sample were analyzed during the stretching process, and the composite material can be understood when the composite material is stretched under force.
The material's ability to resist elongation deformation and fracture characteristics in the elastic range and plastic range
.

It can be seen from the results of the experimental data analysis that with the progress of the tensile experiment, the specimen has obvious deformation and displacement, and the displacement value and strain value of the key parts continue to increase.
Due to the effect of tensile stress, the key parts of the specimen are broken due to fracture.

.
By collecting, recording, measuring and analyzing the failure mode of the tested specimen, data reflecting the mechanical properties of the material can be obtained, and compared with the limit meta-simulation data, so as to better guide the research, design and optimization of composite materials
