The design innovation of aerospace composite parts and components was achieved through automated production technology, which achieved higher production efficiency.
The news revealed that a study on the application of rigid foam materials in automated production is currently underway. The results confirm the use of rigid foam, a closed-cell polymethacrylimide (such as aircraft flaps, spoilers, landing gear doors, and other mass-produced structural components) PMI) various advantages of foam.
The picture above shows the 206B JetRanger helicopter, whose main rotor blades are made of foam core and carbon fiber, and adopt autoclave co-curing technology.
Future capacity growth
The person in charge of the high-performance foam product line said that about 50 years ago, ROHACELL® foam was introduced as the first commercially available PMI foam and used as a core material in sandwich structures. In years of testing and certification, its performance has been repeatedly confirmed, and its application in composite materials has also been continuously expanded. Initially, it was produced at a production site in Darmstadt, Germany.
More than light
Composite sandwich components integrate a lightweight core material and an ultra-thin carbon fiber composite material cover to provide the best mechanical performance at the lightest weight. In addition, ROHACELL® also has excellent strength and stiffness, can withstand high temperatures of up to 220 ° C (428 ° F), and has excellent compressive creep strength at high temperatures.
ROHACELL® foam is used as the core material for lightweight sandwich members, which maintains high shear and compressive strength even at relatively high temperatures.
Today, this rigid foam is widely used in the aircraft, automotive, marine, sporting goods, electronics and medical technology industries.
