Russcomp® HTP is a closed-cell rigid foam based on polymethacrylimide (PMI), which contains no halogen at all. The cell size is fine and uniform.

Russcomp® HTP undergoes heat treatment before delivery.

Processing and production

Russcomp® HTP can withstand a medium temperature curing process with a maximum temperature of 200 ℃ and a maximum pressure of 0.7 MPa, depending on the density. It can be co cured with BMI resin system under harsh conditions of 200 ℃/0.3MPa.Suitable for curing methods such as autoclave, vacuum bag, RTM, VARTM, VARI, HP-RTM, etc.

 Russcomp® HTP boasts excellent properties such as light weight, high strength, heat resistance, easy processability and strong stability. When used in manufacturing high-end composite components for aircraft, aerospace/launch vehicles, unmanned aerial vehicles (UAVs), ships and other fields, it can effectively address the core needs of each application scenario. Detailed explanations are as follows:

1. Aircraft Field

Key Load-Bearing Fuselage Components: The material is often used as the core material for components such as the rear pressure bulkhead stringers of the fuselage and the stiffeners of the airtight cabin spherical frame. For example, the Airbus A380 adopts such PMI foam for the stringers of the rear pressure bulkhead, which significantly enhances the strength and stability of the component structure while reducing the fuselage weight compared with traditional metal materials, helping to improve aircraft fuel efficiency.

Helicopter Rotor Blades: In the manufacturing of helicopter rotor blades, Russcomp® HTP can serve as the core material. For instance, the rotor blades of the British EH-101 anti-submarine helicopter, after adopting this type of PMI foam, can not only withstand complex dynamic loads during flight without easy deformation but also significantly extend the service life of the blades, whose durability is far superior to that of traditional metal blade materials.

2. Aerospace/Launch Vehicle Field

Fairings and Interstages: Components such as the payload fairing, interstage section and intermediate body of launch vehicles have extremely high requirements for material lightweight and structural stability. For example, the US Delta series rockets extensively use the sandwich structure of such PMI foam to manufacture these components, which not only reduces the overall weight of the rocket to improve the effective payload capacity but also resists aerodynamic heating and external pressure during rocket flight, ensuring the safety of internal spacecraft.

Thermal Insulation and Protection Components: Rockets face extreme high-temperature environments during launch and re-entry into the atmosphere. With good thermal stability, Russcomp® HTP can be used to manufacture thermal insulation shields and other protective components of rockets. It can maintain structural integrity under high-temperature conditions, effectively block heat transfer, and prevent internal precision instruments and equipment from being damaged by high temperatures.

3. Unmanned Aerial Vehicle (UAV) Field

Main Fuselage and Wing Structures: UAVs have strict requirements for endurance and maneuverability. The wing and fuselage components made by compounding Russcomp® HTP as the core material with carbon fiber and other materials can greatly reduce the weight of UAVs, reduce energy consumption, and thus extend the endurance range. At the same time, its high specific strength can ensure that the fuselage and wings can withstand air flow impact without deformation in complex flight environments, meeting the mechanical performance requirements of UAVs under working conditions such as high altitude and high speed.
Protective Components for Onboard Equipment: The precision equipment such as reconnaissance and communication carried by UAVs requires reliable protective structures. The material can be used to manufacture protective casings and internal support structures of equipment. With excellent impact resistance and vibration reduction performance, it avoids damage to equipment during flight jolts or take-off and landing impacts, ensuring stable operation of equipment.

4. Marine Field

Core Structures of Hulls and Decks: Using Russcomp® HTP as the core material, compounding with carbon fiber, glass fiber and other materials to form a "panel + foam + panel" sandwich structure, it can be used to manufacture components such as hulls, decks and bulkheads. This structure can reduce the weight of ships by 10%-30%, which not only improves the navigation speed and fuel efficiency of ships but also increases the effective payload of ships. Meanwhile, its closed-cell structure is resistant to seawater corrosion. Compared with traditional metal materials, it can avoid performance degradation caused by salt spray erosion and extend the ship maintenance cycle.

Special Functional Components: In luxury cruise ships or passenger ships, the material can be used in cabin partitions, ceilings and other parts. Its low thermal conductivity and microporous structure can effectively block the noise and heat transfer from areas such as the engine room, improving the riding comfort inside the cabin. In the bow, fenders and other areas prone to impact of military ships or special ships, it can also absorb collision energy relying on excellent impact resistance, reduce damage to the hull caused by collisions, and improve ship navigation safety.

5. Wind Power Blade Field
Russcomp® HTP features high-temperature curing resistance (up to 200℃),
high strength, high stability, lightweight, and fatigue resistance.
It can be used as the core material of the sandwich structure in wind power blades,
applied to key parts such as the leading edge, trailing edge, and shear web.
It can significantly reduce the moment of inertia of the blade and improve wind capture efficiency.
At the same time, it has excellent anti-fatigue performance, which can effectively resist the continuous
alternating loads during blade rotation, extend the service life of the blade, and meet the development
needs of large-scale wind power equipment and large-scale offshore wind power.
