Release High Tech Films used for the Manufacturing of Composites<\/strong><\/span><\/h3>\n

 <\/p>\n

In general, there is a tendency to underestimate how much a modern film can really do<\/strong> in the production of composites,<\/strong> particularly in the manufacture of composite tubes. <\/span><\/p>\n

 <\/p>\n

Most people simply define it as a “release film<\/strong>” referring to the most obvious, but certainly not the most important, function that the film plays in the production of composite tubes. <\/span><\/p>\n

 <\/p>\n

In terms of production costs of raw materials<\/strong>, if it is compared with the costs of prepreg; carbon, kevlar or glass fiber; epoxy, polyester or phenolic resins, the cost of the film is always a small part. <\/span><\/p>\n

 <\/p>\n

If the parameter is instead the total value of the finished composite produc<\/strong>t, the cost of the film is even much smaller, it becomes completely marginal. <\/span><\/p>\n

 <\/p>\n

The perspective changes dramatically if using the wrong film, or misusing the right film, results in a defective product. In both cases the composite may be defective and \/ or its performance limited, lower than what could be obtained. <\/span><\/p>\n

 <\/p>\n

To give an example, a customer recently improved the quality of his tubolar composite simply by reducing the winding pitch of the film. With a large pitch the surface of the composite had small surface holes (\u201cpores\u201d) created by the resin during polymerization. The tubolar item is aesthetic and this superficial defect is unacceptable. With a tighter pitch, and using the same film, all these problems have been solved. <\/span><\/p>\n

 <\/p>\n

Furthermore, generally the film is a consumable material, a component that is thrown away at the end of the production process and, also for this reason, is considered of little importance. <\/span>If design, production and quality control have a superficial approach, and do not dialogue with each other, these strategic characteristics of the films always remain hidden, in the background. If instead production and quality control go in depth, experiment with different production configurations (changing only one parameter at a time) and then refer the results to the design, the best result can quickly be reached, with optimal characteristics of the composite item, and establish a virtuous circle, which allows further improvements to the composite piece. <\/span><\/p>\n

 <\/p>\n

Our experience and the experience of our customers is very different. A proper use of film (or a combination of films) can drammatically improve the result and determine the success or failure of a composite product.<\/span><\/p>\n

A modern film can do really alot in order to help you to get very good composite products. Some of the functions a modern film can accomplish today are the following:<\/p>\n
