Production technologies

The sterilizer process - is the optimal production process of structural parts for maximum properties of composite materials. Raw material in this case is the "Preperg": unidirectional fibers or woven that saturated by resin. This process combined a vacuum, pressure and temperature simultaneously as a function of time. Therefore it is possible to control and adjust parameters so that the above resin polymerization will optimally in terms of removal of volatile and scheduling parameters corresponding viscosities, at every stage of the Cure process.

The RTM process - Resin Transfer Molding Place the fabric fibers inside the template and after closing the resin is injected into the mold with the fabric, so that the resin is absorbed between the fibers in the product after hardening. This process is particularly suitable for producing serial products. This process also involved a vacuum, pressure and temperature as a function of time, although it operated vacuum, volatile and not level out spatial form as in the sterilizer. In this work process the raw material is fabric or shaped fabric Preform the number of layers as required, and the resin liquid comes separately. Disadvantage of the RTM process is the high cost of tools required format as male - female fit and means of heating. It also required the appropriate resin injection equipment also includes heating means of the mixing tank and pipeline. Therefore the production cost of the individual parts will be very high (cost template may reach hundreds thousands of dollars).

In LRI process - we place the fabric fibers in a template and closes on him the vacuum bag containing vacuum bag arrangement corresponding to this process.

on the one hand were connecting the resin tank, and on the other hand we pulls the vacuum until the resin is absorbed and fill in the fabric.The Parameters involved in this process are only the vacuum and temperature depending on time, without applying pressure. Therefore, the resulting product properties occupied by lower-LRI compared to features of the conquered products and processes of saturated   the sterilizer and also in RTM. Therefore this process should be invested in development in order to get the best features and to characterize them. This workflow also the raw material is cloth or shaped fabric Preform , and the liquid resin comes separately. LRI process advantage is the low cost of manufacturing the parts due to a relatively simple format, without the need for resin injection device or sterilizer.
