In January 2020, the US Composites World website released a series of research reports "Composite Materials 2020 - Many Market Opportunities", summarizing and looking forward to the status quo, opportunities and challenges of the development of the global composite materials industry in 2020
.
The report believes that entering 2020, the main factors affecting the composite manufacturing industry include robotics or automation technology, high temperature autoclave curing process, thermoplastic composite technology, composite 4.
0 and additive manufacturing technology
.
According to the report, the manufacturing industry likes to think of composites manufacturing as a separate, global entity that meets customer needs by forming a variety of highly engineered components and structures
.
But in reality, the composites industry is a collection of many highly vertical markets (such as aerospace, automotive, marine, consumer goods, wind energy, etc.
) that consume composites in a variety of different ways
.
Composite materials are inherently diverse, so they can meet a diverse set of needs
.
Despite the highly customizable nature of composites, megatrends in materials and processes in general will undoubtedly impact the composites industry as a whole in the coming years, according to the report
.
First of all, robots and automation technology will be widely used, gradually replacing human labor in the manufacturing process
.
Second, the composites industry will strive to move away from the limitations of the autoclave curing process
.
For this reason, the introduction of out-of-autoclave (OOA) materials and processes, such as thermoplastic composites, resin infusion and resin transfer molding (RTM) processes, has been given more serious consideration in various application areas.
to production, especially in the manufacture of large commercial aerospace structural components
.
Thirdly, the development of thermoplastic composites shows a clear upward trend in general
.
Mainly because this material has the following properties: it can be processed using OOA, is easier to store and handle (compared to prepreg) and is easy to recycle
.
Fourth, the era of "composite materials 4.
0" has come
.
Industry 4.
0 in the composites industry has officially entered the public eye.
Its main connotation is that the composites industry has a complete digital manufacturing process—from design to simulation, to manufacturing simulation, to composite manufacturing, to troubleshooting.
, and finally until tracking the performance status of each component,
etc.
The development of this capability will lead to the development and use of more sophisticated algorithms to control intelligent machines that meet the future manufacturing environment and can manufacture the next generation of composite materials
.
Fifth, the large-scale development of additive manufacturing technology in composite manufacturing
.
Preliminary use of chopped fiber reinforcements in thermoplastic-based composite additive manufacturing, showing that it is already possible to manufacture individual parts, tooling, and mold assemblies using continuous fiber reinforcements
.
In addition, the industry has also discovered additive manufacturing technologies based on thermoset composites, as well as the emergence of new processes that combine additive manufacturing with AFP/ATL
.
All of these technologies drive the highly dynamic and rapidly changing composites industry to continue to move forward
.
