This production process is used for almost all advanced composite components. More specifically, this technique is used in the aircraft industry where materials, training of production personnel and the treatment cycle are regulated by a series of highly detailed specifications, thus making this a special process. The \u201claminators\u201d, highly skilled technicians responsible for laying out the pre-impregnated laminate to specific designs, are crucial to the process and can affect the quality of the moulded parts: an oversight during the lamination process or forgetting to add layers during the construction of the laminate can lead to unnecessary waste or even to the failure of a structural element. The considerable manual intervention required in autoclave technology also affects productivity levels. On the other hand, the components produced using this technology have a high fibre\/matrix ratio and an excellence adhesion\/strength ratio, making them ideal for aircraft.<\/span><\/span><\/p>\n<p><span style=\"font-family: Calibri, sans-serif;\"><span style=\"font-size: medium;\">The geometrical designs of the components produced this way are, however, often very simple, &quot;linear&quot; and far from having the complexity possible with metal. This limit is based on the fact that the reinforcement fabrics are planar structures that, in order to become non-developable complex 3D shapes, require a lot of distortion, cutting or even overlapping, leading to problems with their thickness and very complex designs, especially in terms of mechanical simulation.<\/span><\/span><\/p>\n<p><span style=\"font-family: Calibri, sans-serif;\"><span style=\"font-size: medium;\">Cuts, overlapping, distortion, these all change the intrinsic properties of the composite and thus its elastic coefficient. Moreover, ultimate strength tests on flat samples need to be applied to 3D structures, causing a certain degree of uncertainty and hence some often very high safety factor findings. <\/span><\/span><\/p>\n<figure id=\"attachment_25930\" aria-describedby=\"caption-attachment-25930\" style=\"width: 300px\" class=\"wp-caption alignright\"><a href=\"https:\/\/i-hls.com\/wp-content\/uploads\/2013\/12\/fig-1-fiber-contect-vs-productivity.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-25930\" alt=\"Fig. 1 - fiber content vs. productivity\" src=\"https:\/\/i-hls.com\/wp-content\/uploads\/2013\/12\/fig-1-fiber-contect-vs-productivity-300x266.jpg\" width=\"300\" height=\"266\" srcset=\"https:\/\/i-hls.com\/wp-content\/uploads\/2013\/12\/fig-1-fiber-contect-vs-productivity-300x266.jpg 300w, https:\/\/i-hls.com\/wp-content\/uploads\/2013\/12\/fig-1-fiber-contect-vs-productivity.jpg 319w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><figcaption id=\"caption-attachment-25930\" class=\"wp-caption-text\">Fig. 1 &#8211; fiber content vs. productivity<\/figcaption><\/figure>\n<p><span style=\"font-family: Calibri, sans-serif;\"><span style=\"font-size: medium;\">Meanwhile, other production processes have been developed, thanks to strong pressure from the automotive industry.

The typical &quot;H&quot; shape is normally achieved by bending the flat part of the material to the web of the beam. However, if the beam is not prismatic and has far more complex forms, this construction logic leads to problems because the distortion limits of the reinforcing materials dictate a narrow range of feasible shapes. <\/span><\/span><\/p>\n<figure id=\"attachment_25937\" aria-describedby=\"caption-attachment-25937\" style=\"width: 300px\" class=\"wp-caption alignleft\"><a href=\"https:\/\/i-hls.com\/wp-content\/uploads\/2013\/12\/Fig-8a-\u2013-Standard-beam-concept-vs.-RTM-concept-with-butt-joint.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-25937\" alt=\"Fig. 8 \u2013 Standard beam concept vs. RTM concept with butt-joint\" src=\"https:\/\/i-hls.com\/wp-content\/uploads\/2013\/12\/Fig-8a-\u2013-Standard-beam-concept-vs.-RTM-concept-with-butt-joint-300x211.jpg\" width=\"300\" height=\"211\" srcset=\"https:\/\/i-hls.com\/wp-content\/uploads\/2013\/12\/Fig-8a-\u2013-Standard-beam-concept-vs.-RTM-concept-with-butt-joint-300x211.jpg 300w, https:\/\/i-hls.com\/wp-content\/uploads\/2013\/12\/Fig-8a-\u2013-Standard-beam-concept-vs.-RTM-concept-with-butt-joint-400x281.jpg 400w, https:\/\/i-hls.com\/wp-content\/uploads\/2013\/12\/Fig-8a-\u2013-Standard-beam-concept-vs.-RTM-concept-with-butt-joint.jpg 509w, https:\/\/i-hls.com\/wp-content\/uploads\/2013\/12\/Fig-8a-\u2013-Standard-beam-concept-vs.-RTM-concept-with-butt-joint-508x357.jpg 508w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><figcaption id=\"caption-attachment-25937\" class=\"wp-caption-text\">Fig. 8 \u2013 Standard beam concept vs. RTM concept with butt-joint<\/figcaption><\/figure>\n<p><span style=\"font-family: Calibri, sans-serif;\"><span style=\"font-size: medium;\">It follows that should one wish to create this type of component in a composite material or replace the machined metal element, the shape of the entire beam needs to be redesigned. The construction concept proposed by Lamiflex, on the other hand, combined with the use of appropriate reinforcing materials, makes it possible to create a wide range of shapes. Figure 8 (left) shows how the high degree of distortion required of the reinforcement in the corners (clearly not feasible) would lead to the elimination of the corner itself, thus creating an open and inherently less rigid structure than that shown in Figure 8 (right), which is easily produced as shown in Figure 9 (right).<\/span><\/span><\/p>\n<figure id=\"attachment_25938\" aria-describedby=\"caption-attachment-25938\" style=\"width: 300px\" class=\"wp-caption alignright\"><a href=\"https:\/\/i-hls.com\/wp-content\/uploads\/2013\/12\/Fig-8b-\u2013-Standard-beam-concept-vs.-RTM-concept-with-butt-joint.png\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-25938\" alt=\"Fig. 8 \u2013 Standard beam concept vs. RTM concept with butt-joint\" src=\"https:\/\/i-hls.com\/wp-content\/uploads\/2013\/12\/Fig-8b-\u2013-Standard-beam-concept-vs.-RTM-concept-with-butt-joint-300x230.png\" width=\"300\" height=\"230\" \/><\/a><figcaption id=\"caption-attachment-25938\" class=\"wp-caption-text\">Fig. 8 \u2013 Standard beam concept vs. RTM concept with butt-joint<\/figcaption><\/figure>\n<p><span style=\"font-family: Calibri, sans-serif;\"><span style=\"font-size: medium;\">If we consider the shape shown in Figure 2, obtained by machining a solid lump of metal, Figure 9 shows the typical approach adopted to get this shape using composite materials.

An important innovation has been the creation of the carbon mould temperature control system using a set of heating elements incorporated in the mould and controlled by an external PLC heating unit with PID control. The latter also records signals from thermocouples used to construct the temperature profile of the pre-form and the mould inside this. This has made it possible to verify the correct temperature distribution and optimise the curing cycle in detail.
