Airplane Use Aramid Honeycomb Panel with Carbon Fiber Unidirectional Prepreg and Epoxy Resin Cured at Medium Temperature

Product Description

Carbon Fiber Prepreg Aramid Honeycomb Panel for Shipbuilding Use With Epoxy Resin is a very light weight aramid honeycomb panel comprised of an aramid honeycomb core with two carbon fiber epoxy resin prepreg produced surface plates. The surface plates are produced from carbon fiber prepreg impregnated with epoxy resin.

A carbon fiber unidirectional (UD) fabric is the one in which the majority of yarns (80% and above) distributed in one direction only. A small amount of fibre or other material may be used in other direction with the main intention being to hold the primary yarn in position, although the other fibres may also offer some structural properties. Some weavers of 0/90° fabrics term a fabric with only 75% of its weight in one direction as a unidirectional, whilst for others the unidirectional designation only applies to those fabrics with more than 90% of the fibre weight in one direction. Unidirectionals usually have their primary fibres in the 0° direction (along the roll ­ a warp UD) but can also have them at 90° to the roll length (a weft UD).

Features of Aramid Honeycomb Panel:

1. high temperature resistance makes the panel can be hot pressed into shape under the temperature more than 200 ℃

2. 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

3. 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

4. High rigidity, high resistance to damage compared with other honeycomb core materials

5. Flame retardant, low smoke and low toxicity (in line with the most stringent flame retardant and smoking standards of aviation);

6. Excellent creep and fatigue properties, can be used in strict requirement for long term use

7. Extremely high wet strength, can be used in high humidity environment. Easy to process with reduced production cost;

8. corrosion-resistant (not corroded by moisture or other medium or electrochemical reaction with carbon fiber, like a metal honeycomb);

9. 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;

10. 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.
