International teamwork between Isojet Equipements and JR Technology Limited (JRTL) is set to revolutionise resin applications in aerospace and allied industries.
According to JRTL, the culmination of several years’ collaboration saw it install a bespoke two component (2K) resin mixing and dispensing machine at the OEM’s research and development facility last week. It says the machine is a world first in allowing the chemists to develop new resin systems, giving them full flexibility in all aspects of the RTM process.
JRTL says that,unlike traditional models on the market, this Isojet 2K machine is used in the development of new resin systems. Until now, all RTM adhesives have been single component (1K) which makes them very unstable to transport, with a maximum 10kg container.
This new machine allows the operator to regulate the temperature and pressure throughout the degassing, mixing and dispensing process, including heating and degassing of the tool prior to injection. One of the components is crystalline prior to processing and won’t flow until it reaches a temperature of 80+ degrees C. Therefore every part of the machine is heated, including the volumetric flow meters. It can operate over a range of pressures (0-25bar injection pressure) and flow rates (0 -0.5kg per minute injection flow). There is also a data logging feature. A 19-inch full-colour touch-screen monitor displays temperatures and pressures of all parts of the process and the unit is self-contained and fully mobile.
Paul Rogger, Technical Director of JRTL, explains, “We’re proud to have been involved in getting this unique machine up and running. As Isojet’s UK agent and service engineers, we appreciate the technical challenges in developing revolutionary technology to overcome specific problems with composite processes and applications. This 2K machine has certainly achieved this.”
Henri-Pierre Hiblot, CEO of Isojet Equipements, said, “We are delighted to have designed this 2K Machine with its unique capabilities. We have a long history of design and innovation of multi component injection machines and it is always rewarding when the finished product pushes the boundaries and advances engineering technology.”
Alvant has been appointed to work on a two-year, £28 million project titled Large Landing Gear of the Future, which aims to deliver a 30% weight reduction and assist the aerospace industry’s drive to reduce fuel consumption and carbon emissions.
Hexadrone’s 3D printed Tundra prototype, manufactured by CRP Technology via laser sintering (LS) technology using Windform SP and Windform XT 2.0 carbon composite materials, has won the Red Dot Award 2018 in the drone category.
UK company Norco Composites has invested in a larger spray booth and a new cutting and kitting machine to enable the company to increase productivity in line with growing demand from its marine customers.
