Aluminum frame doors, even in large sizes, covered in thin ceramic or glass.
In the photo, the doors have a solid wood perimeter for processing:
- 45° cut in the thickness for grip. - Hardware insertion for doors and drawers. - Edged in ABS.

Stratigraphic study
Stratigraphic study
Every Panel Starts with Its Layup.
Every composite panel begins with an analysis of the application. The layup design process is how we define materials, core, facings, thicknesses, inserts, and manufacturing operations to achieve the optimal balance of performance, weight, stiffness, strength, and manufacturability.

Aluminumhoneycomb
Our aluminum honeycomb, can be:
- in 3003 alloy with 0.05 mm thickness;
- in 5052 alloy with 0.06 mm thickness;
In aluminum with micro-perforation suitable for air exchange between the cells to avoid a possible detaching effect caused by an increase in air volume due to heat inside the closed cells.
In perforated aluminum on the cell walls to allow the passage of airflow for specific applications that require high vacuum or strong decompression.
High rigidity and strength
Excellent stiffness / weight ratio
dimensional stability
Nomex honeycomb®
The NOMEX® honeycomb is made of aramid paper impregnated with resin, which ensures specific fire and humidity resistance performance as well as resistance to marine salt.
Excellent resistance to the fire
High lightness
Good mechanical properties
Polyethylene terephthalate
-PET- Polyurethane foams
Polyethylene terephthalate, whose acronym is PET, is a thermoplastic resin belonging to the polyester family, composed of phthalates.
It is also used for its electrical properties, chemical resistance, high temperature performance, and self-extinguishing capability.
The good mechanical properties and FST (fire and smoke) characteristics of the material allow its use in the naval and construction sectors.

Support thickness
Cell diameter
It is possible to choose 2 different cell densities.
A higher density increases the mechanical performance of the panel and the resistance to bending with only a slight increase in weight per cubic meter.
ALUMINUM HONEYCOMB
from 3/8 (8.66 mm) corresponding to 40 Kg/mc
from 1/4 (6.25 mm) corresponding to 80 Kg/mc
from 1/8 (3.12 mm) corresponding to 120 Kg/mc
(for panels with reduced thickness or that require
greater resistance to bending)
NOMEX® HONEYCOMB
from 1/16 (3.2 mm) corresponding to a weight of 48 Kg/mc
from 3/16 (1.8 mm) corresponding to a weight of 60 Kg/mc
The thickness in combination with the cell diameter defines the mechanical characteristics of the panel.
It is possible to produce any thickness on request, from 8 mm up to 60 mm.
SKINS SELECTION
Optimized stratigraphy for each project
A major advantage is the ability to create asymmetric and multi-layer panel constructions
Not all composite panels are symmetrical. In many applications, each face of the panel is required to perform a different function.
Panels can be engineered with:
• Different surface materials on each face
• Different skin thicknesses
• Different material combinations
• Multiple material layups
This design flexibility makes it possible to optimize mechanical performance, weight, aesthetics, and cost simultaneously.
example
The skins can be:
STRUCTURAL in thin aluminum, steel or in composite material in fiberglass, carbon or kevlar
COATING connected to the structural skins to achieve the desired decorative purpose
Structural skins
Structural skins are those surfaces that make up the panel and serve to provide structure and stability to the panel and can be made of:
- Aluminum or metal
- Steel
- G10 fiberglass
- Nomex®
- Kevlar®, one or more layers
To optimize sound absorption or thermal insulation characteristics, it is possible to combine a cork skin with the structural skins
Covering skins
The covering skins are those surfaces that cover the panel, giving it the desired decorative purpose, and can be in:
- High pressure laminate
- Veneer
- Solid wood max 6 mm thick
- MDF
- Glass
- EpoxyPrepreg
Glue
Structural adhesives have different chemical formulations depending on the nature of the materials to be joined:
- Epoxy adhesives for structural use and for bonding composite materials.
- Primers to increase adhesion and surface protection
- Foaming adhesives to seal joints between the same components
- Epoxy adhesive films for bonding surfaces.
Every Panel Starts with Its Layup.
A composite panel is not simply a combination of different materials. It is the result of an engineering process in which every layer is designed to meet the performance requirements of the final application.
Facing materials, core, thicknesses, reinforcements and the panel layup are all engineered to achieve the optimum balance between lightweight construction, stiffness, strength, durability and manufacturing cost.
