High Strength to Weight Ratio Aramid Honeycomb Door Panel with
Carbon Fiber Surface Prepreg Plates
Product Description
High Strength to Weight Ratio Aramid Honeycomb Door Panel with
Carbon Fiber Surface Prepreg Plates is comprised of a nomex
honeycomb core with two carbon fiber prepreg produced surface
plates while the nomex is the aramid fiber brand of Dupong company.
It is widely used for the yacht door panel. The surface plates are
produced from fiberglass or carbon impregnated with phenolic,
epoxy, or other type thermosetting or thermoplastic resins. The
finished products possess good properties of light weight and high
strength which are very important for yacht manufacturing.
Furthermore, the nomex honeycomb panel is with fungi resistance,
non combustible and moisture resistance. The yacht should be on
water and sometimes in sea water. These combined good properties
are very important for the shipbuilding industry.
Features of Aramid Honeycomb Panel:
A. high temperature resistance makes the panel can be hot pressed
into shape under the temperature more than 200 ℃
B. 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
C. 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
D. High rigidity, high resistance to damage compared with other
honeycomb core materials
E. Flame retardant, low smoke and low toxicity (in line with the
most stringent flame retardant and smoking standards of aviation);
F. Excellent creep and fatigue properties, can be used in strict
requirement for long term use
G. Extremely high wet strength, can be used in high humidity
environment. Easy to process with reduced production cost;
H. corrosion-resistant (not corroded by moisture or other medium or
electrochemical reaction with carbon fiber, like a metal
honeycomb);
J. 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;
K. 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.
