Pressure Points | Why Pressure Sensing is So Crucial for Achieving High Quality
The significance of precise in-mould pressure measurement in resin transfer moulding (RTM) and infusion processes has been widely acknowledged in the composites industry.
As the aerospace industry continues to look at Out of Autoclave processes, detailed examination of process variables and how to control them is paramount.
The benefits of Liquid Resin Infusion and RTM are diverse. Reduced CAPEX and OPEX, along with significant efficiency and energy savings can be achieved while also significantly improving manufacturing rate.
As part of this requirement, Composite Integration has collaborated with aerospace clients for more than 20 years, evaluating and developing the key principles necessary to produce very high-quality composite parts in an Out of Autoclave method.
Figure 1 represents an example of the type of process envelope which must be followed to ensure the quality and repeatability required by this sector.

One of the key fundamentals necessary for both measurement and control on liquid processes is pressure. Vacuum level measurement is a given, but careful control of liquid resin pressure is less well understood and has a significant impact on final laminate quality, volume fraction (Vf) and void content.
Pressure measurement is key in various stages of the manufacturing timeline, including pre- infusion, during infusion and post infusion. Information provided from pressure sensors is used at each of these stages to ensure correct management and control of the process.
Innovations over the past few years have led to the development of a reusable ceramic In Mould Pressure Sensor (IMPSTM) capable
of directly measuring resin pressures across diverse temperature and pressure conditions and permits meticulously controlled resin delivery and cure. This allows for exceptional accuracy and consistency in composite part production, which is crucial for both quality and performance.

CI Showcases Expertise at Tooling for Composites Event
Composite Integration, a leading provider of composite tooling and manufacturing equipment, attended the recent Tooling for Composites event on July 19, 2023, at Spirit AeroSystems in Prestwick, Scotland. The event was organised by Composites UK.
Tim Searle, Research and Development Director at Composite Integration, gave a presentation titled “The Right Tool for the Right Job (RTM & Infusion)” Tim presented the company’s expertise in a variety of tooling applications, including insights into the factors that should be considered when selecting the right tooling for a particular application.
During the event, Composites UK announced the publication of the Tooling Good Practice Guide. The guide provides a wealth of information about a fundamental part of composite manufacturing. Industry experts collaborated to create the guide, which is a useful resource for people from new trainees to clients specifying tools. Richard Bland, Technical Director at Composite Integration, contributed to the chapters on the design and construction of tooling and reviewed the document alongside Tim Searle.
The guide is a valuable resource for anyone involved in the design, manufacture, or use of composite tooling. It is available to download from the Composite UK website.
The Tooling for Composites event was a great opportunity for Composite Integration to showcase its expertise and network with other industry professionals. The positive feedback from the audience is a testament to the quality of Tim’s presentation and the company’s capabilities.
Composite Integration’s presentation at the Tooling for Composites event was a well-attended and successful event.
