LAMINATION

We carry out the entire production cycle: starting from the lamination of carbon fiber, Kevlar and glass fabrics, to subsequent cutting, shaping and composition in sandwich panels.

Lavorazione di tessuti tecnici

Our production process
FABRIC CUTTING : Pre-preg fabrics in rolls are spread and cut with an automated system in the dimensions necessary for rolling
MOLDING CYCLE : The lamination takes place with a double press system: First hot press which allows the control of the temperature, of the pressure and of the necessary degassing cycles. The maximum operating temperature can reach 180 ° degrees; the maximum working pressure is between 9 and 13 Kg / cm; second cold press with cryogenic system stabilizes and completes the polymerization cycle of the fabric matrices.
MILLING : the pieces are cut, drilled and milled using a CNC machining center.
THERMOFORMING :  molding of hot materials, starting from sheets or film, under pressure or under vacuum.
Our continuous investment in research and new production facilities means that all the processes are carried out within our company, maintaining direct control and guaranteeing the confidentiality of information.

Materials we work:

TEXTILES
Pre-impregnated fabrics
The pre-impregnated products are made with all types of compatible fabric, from polyester to carbon fiber, through the application of resins, generally epoxy.
Shielding pre-impregnated fabrics
The shielding pre-impregnated with respect to the other pre-impregnated fabrics have in addition a "nickel plating bath" which gives high shielding properties to the pre-impregnated fabric. Properties that give protection from electromagnetic waves.
Polyethylene laminated fabrics
They are dry fabrics coupled with a thermoplastic polyethylene film.
FIBER COMPOSITE
Glass fiber
In structural fabrics, glass fibers are characterized by excellent elasticity, high mechanical strength and low density.
Kevlar fiber
The fibers and kevlar are characterized by a remarkable resistance to traction, impact and corrosion. Furthermore, the kevlar laminates have no electrical conductivity and are heat resistant.
Carbon fibers
The fibers and carbon are characterized by a high mechanical resistance for the same weight, resistance to the action of chemical agents, excellent fireproof properties.
RESINS

Thermosetting resins

Thermosetting resins have a non-reversible heat-activated polymerization process. In general, thermosetting resins give mechanical properties of low shrinkage to molding, resistance to chemical agents (acids, bases, solvents), temperature resistance, low dielectric constant, excellent adhesion on metals and fibers.
 
Thermoplastic resins
Thermoplastic resins are characterized by a change of state, from plastic to rigid and vice versa, which can be reactivated by means of heat. This allows the fabrics coupled with these resins to be thermoformed.
