HP Composites is the ideal partner for the production of advanced composite materials. We are able to manage every kind of process and we are in possession of the technologies for every type of application.
Autoclave
Used for the production of complex parts such as monocoque or parts of the air-space industry. Internal pressure and temperature are controlled in such a way as to make the pieces in different ways according to the size and material used. Through this technology composite component parts are produced with epoxy resins and the reinforcement is made of carbon fiber or kevlar and / or other fibers.
Press
It allows to have high quality and uniformity aesthetics with short cycle times. Repeatability allows the production of structural parts and carbon look in series. This technology makes it possible to produce pieces of small and medium complexity.
Press Moulding
The cure cycle is carried out under press in heated molds. Normally short fiber is used and it is suitable for the construction of small parts, not hollow or inserts.
Forming Prepreg
Technology developed in the aeronautical sector to industrialize the manual rolling phase. It consists in the «hot forming» of pre-prepared packets to be printed then in a press or in an autoclave. The forming takes place thanks to the application of heat and vacuum on a pre-formed package placed on a mold;
Air Press Moulding
Technology developed by HP Composites. The idea was developed by trying to create a productive process that would be placed between autoclave and press production, drawing the benefits from both of them. This technology is ideal for large pieces. Its use allows to obtain high productivity maintaining the balance between cost and performance
RTM
Traditional technology. It consists in the injection of resin under pressure through dry fiber preforms contained in closed rigid molds. Limited fiber / resin ratio. It adapts to simple geometries, with a high thickness and preferably with not excessive dimensions. Normally the (metal) molds are heated and contrast the injection forces (press).
VRTM
Similar to RTM technology with the difference that injection pressures are very low and assisted by vacuum. No metal counter-molds or the press are necessary. Very limited performances. HP has developed a variant of the VARTM and the infusion that allows injecting more reactive resins and drastically reducing the empty contents;
