Abstract
Description
De manera opcional, adicionalmente a la etapa b) se procede a un post-curado, para conseguir propiedades mecánicas mejoradas cuando así se requiera o los materiales de la porción lo permitan. Optionally, in addition to step b) a post-cure is carried out, to achieve improved mechanical properties when required or as the materials of the portion allow.
De manera preferida, la matriz empleada puede ser de tipo termoestable (“epoxi”, fenólica u otras), o bien termoplástica (PP, PA, PEEK u otras) u otra. Preferably, the matrix used can be of the thermostable type ("epoxy", phenolic or others), or thermoplastic (PP, PA, PEEK or others) or other.
Cuando la matriz es termoestable, previamente a la etapa b) se procede a alimentar el interior de la cavidad con la matriz para poner en contacto las fibras de material compuesto con dicha matriz, curándose dicha matriz con las fibras de material compuesto en la etapa b). En este caso las fibras de material compuesto presentarán una sección transversal cuyas dimensiones sean ligeramente inferiores a la sección transversal de la cavidad para dar cabida a la matriz; When the matrix is thermostable, prior to step b) the interior of the cavity is fed with the matrix to bring the fibers of composite material into contact with said matrix, said matrix being cured with the fibers of composite material in stage b ). In this case the composite fibers will have a cross section whose dimensions are slightly smaller than the cross section of the cavity to accommodate the matrix;
Para alimentar el interior de la cavidad con la matriz, se pueden infusionar las fibras de material compuesto, succionando la matriz en el interior de la cavidad mediante la generación de vacío en dicha cavidad; al generar el vacío se evita así la creación de burbujas en el interior de la cavidad que podrían disminuir drásticamente las propiedades mecánicas en determinados puntos a lo largo de la longitud del perfil estructural. To feed the inside of the cavity with the matrix, the fibers of composite material can be infused, by sucking the matrix inside the cavity by generating vacuum in said cavity; generating the vacuum thus avoids the creation of bubbles inside the cavity that could drastically decrease the mechanical properties at certain points along the length of the structural profile.
La succión de la matriz se lleva a cabo preferentemente desde una abertura de la cavidad a otra, estas pueden ser los orificios de la cavidad en cada uno de los extremos opuestos del perfil estructural. Suction of the matrix is preferably carried out from one opening of the cavity to another, these can be the holes in the cavity at each of the opposite ends of the structural profile.
En otra alternativa para alimentar la matriz, previamente a la etapa b) se inyecta la matriz en la cavidad donde están dispuestas las fibras de material compuesto. En este caso, gracias a la presión ejercida también se evita la aparición de burbujas. In another alternative to feed the matrix, prior to step b) the matrix is injected into the cavity where the composite fibers are arranged. In this case, thanks to the pressure exerted, the appearance of bubbles is also avoided.
En el caso de que el perfil estructural presente una ranura que comunique el interior de la cavidad con el exterior, está previsto que se proceda a cerrar herméticamente y de forma reversible dicha ranura por lo menos en la etapa b). Así se consigue aportar o fundir la matriz en un molde cerrado, sin pérdidas. In the event that the structural profile has a groove that communicates the inside of the cavity with the outside, it is provided that said groove be sealed and reversibly closed at least in step b). Thus it is possible to contribute or melt the matrix in a closed mold, without losses.

materiales relativamente asequibles como aluminios, aceros, aleaciones u otros metales debe ser también considerado. Relatively affordable materials such as aluminum, steels, alloys or other metals should also be considered.
De forma alternativa, el perfil estructural 1 también puede estar hecho de material plástico técnico. No se entrará en mayor detalle con el tipo de plástico técnico puesto que podrá ser cualquier disponible en el mercado y adecuado para el uso en la presente invención. Alternatively, the structural profile 1 can also be made of technical plastic material. It will not go into greater detail with the type of technical plastic since it may be any available in the market and suitable for use in the present invention.
Continuando con las figuras 2-4, el perfil estructural 1 comprende por lo menos una cavidad 4 alargada dispuesta en la dirección longitudinal del perfil estructural 1. En los ejemplos mostrados en las figuras 2 y 3, hay provistas dos cavidades 4 y en el ejemplo de la figura 4, hay cuatro cavidades 4. En función de las necesidades puntuales de cada diseño, el experto en la materia podrá variar de manera evidente el número y la forma de las cavidades 4. Continuing with Figures 2-4, the structural profile 1 comprises at least one elongated cavity 4 arranged in the longitudinal direction of the structural profile 1. In the examples shown in Figures 2 and 3, two cavities 4 are provided and in the example of figure 4, there are four cavities 4. Depending on the specific needs of each design, the person skilled in the art can obviously vary the number and shape of the cavities 4.
En cualquiera de los ejemplos mostrados, el perfil estructural 1 presenta ventajosamente una sección transversal en la que dichas cavidades 4 comprenden una porción 5 de material compuesto, presentando el perfil estructural 1 una sección transversal mixta en la que dicha cavidad 4 está dispuesta de modo que está desplazada por lo menos una distancia H1 respecto al centroide G de la sección transversal mixta de dicho perfil estructural 1. In any of the examples shown, the structural profile 1 advantageously presents a cross-section in which said cavities 4 comprise a portion 5 of composite material, the structural profile 1 presenting a mixed cross-section in which said cavity 4 is arranged so that at least one distance H1 is displaced from the centroid G of the mixed cross section of said structural profile 1.
En los casos ilustrados, se puede ver que el perfil estructural 1 comprende por lo menos un par de cavidades 4 con la porción 5 de material compuesto, estando desplazadas las respectivas cavidades 4 entre sí. Hay una separación entre cavidades 4 definida como distancia H superior a las respectivas distancias H1 entre cada una de las cavidades 4 y el centroide G de la sección transversal mixta de dicho perfil estructural 1. De forma preferida, la separación mínima entre dos cavidades 4 puede ser la distancia mínima entre ellas, es decir, los respectivos puntos perimetrales de la cavidad vista en sección transversal del perfil estructural 1. In the cases illustrated, it can be seen that the structural profile 1 comprises at least one pair of cavities 4 with the portion 5 of composite material, the respective cavities 4 being displaced from each other. There is a gap between cavities 4 defined as distance H greater than the respective distances H1 between each of the cavities 4 and the centroid G of the mixed cross section of said structural profile 1. Preferably, the minimum separation between two cavities 4 can be the minimum distance between them, that is, the respective perimeter points of the cavity seen in cross section of the structural profile 1.
Esta porción 5 puede comprender por lo menos un elemento pultrusionado o por lo menos una preforma tejida. Alternativamente la porción 5 también puede comprender fibras secas. En cuanto al material compuesto, puede escogerse de entre fibras de carbono, fibras de vidrio, fibras de aramida u otras, aunque en una realización preferida se emplean fibras de carbono, porque la fibra de carbono se plantea como el tipo de fibra cuyas propiedades mecánicas pueden optimizar en mayor grado el perfil estructural 1. No obstante, This portion 5 may comprise at least one pultruded element or at least one woven preform. Alternatively, portion 5 may also comprise dry fibers. As for the composite material, carbon fibers, glass fibers, aramid fibers or others can be chosen, although in a preferred embodiment carbon fibers are used, because carbon fiber is considered as the type of fiber whose mechanical properties they can further optimize the structural profile 1. However,
