Very Light Weight Aramid Honeycomb Panels High Temperature Resistance
Very Light Weight Aramid Honeycomb Panels High Temperature Resistance is a very light weight aramid honeycomb panel comprised of an aramid honeycomb core with two carbon fiber prepreg produced surface plates with benzoxazine resin. The surface plates are produced from carbon fiber prepreg impregnated with benzoxazine resin.
Benzoxazines formed by the reaction of phenols, formaldehyde and primary amines which on heating to ~400 °F (~200 °C) polymerise to produce polybenzoxazine networks. The resulting high molecular weight thermoset polymer matrix composites are used where enhanced mechanical performance, flame and fire resistance compared to epoxy and phenolic resins is required.
Features of Aramid Honeycomb Panel:
First, high temperature resistance makes the panel can be hot pressed into shape under the temperature more than 200 ℃
Second, Wide range of density from29-160 kg/m3 of the core, if reinforced with carbon prepreg plates, the total area weight can be very low to 30g/m2; therefore it can meet many clients requirement on weight
Third, Extremely high shear strength, especially compared with foam core material, more suitable for use in light structure. It is considered to be a light weight but high strength composite honeycomb core material
Fourth, High rigidity, high resistance to damage compared with other honeycomb core materials
Fifth, Flame retardant, low smoke and low toxicity (in line with the most stringent flame retardant and smoking standards of aviation);
Sixth, Excellent creep and fatigue properties, can be used in strict requirement for long term use
Seventh, Extremely high wet strength, can be used in high humidity environment. Easy to process with reduced production cost;
Eighth, corrosion-resistant (not corroded by moisture or other medium or electrochemical reaction with carbon fiber, like a metal honeycomb);
Nineth, superior heat and sound insulation performance, compared with metal and glass fiber materials, under the same weight with better insulation and sound insulation performance, more comfortable and energy conservation and environmental protection;
Tenth. Easy forming process, compared with the metal honeycomb, the aramid honeycomb can be curved form, the processing is more convenient, the operation is more convenient.
