COMPOSITE CONSTRUCTION FOR FIXED AND MOVABLE SURFACES

Description

Technical area

[0001] The present invention relates generally to a composite construction for fixed and movable surface elements, such as windows, doors, panels and facade elements, as well as the fixed or movable surface elements themselves obtainable thereby. State of the art

[0002] Numerous composite profiles and composite profile frame systems are known from the state of the art. They are preferably made of metal or a metal alloy and can be exposed to adverse weather conditions and strong temperature fluctuations between their inside and outside. A large temperature difference between the outside of the profile frame system, i.e. the side located outside the building, and the inside of the profile frame system generally proves to be problematic from a thermal engineering perspective. To prevent thermal bridging, such composite profile systems usually connect two metallic frame profiles (inner and outer profiles) using one or more less thermally conductive plastic insulating strips, also called separating strips, to achieve thermal separation or decoupling between the inside and outside.

[0003] Since the connection between the two frame profiles and the separating webs must of course also meet other structural requirements, such as loads due to tensile or compressive, shear, bending and torsion, as well as aesthetic requirements, the problem of the so-called bimetallic effect arises as the size increases due to the thermal separation within the connection described above while at the same time maintaining a force-fitting connection. Generally speaking, the bimetallic effect occurs when two materials with different thermal expansion coefficients are connected and deformation occurs due to the different expansion. Such difficulties due to repeated large temperature differences mainly occur in surface elements in external walls, for example in winter between the inside of the room and the outside air, and in summer when solar radiation leads to an increase in the temperature of the external profile.This deformation is more pronounced the greater the temperature difference between inside and outside, the better the thermal separation between the inside and outside profiles, the larger the dimensions of the windows, doors and facade elements, the more they are exposed to the sun and the better they absorb sunlight and infrared radiation.

[0004] What makes matters worse is that the fillings enclosed in these composite profiles are not only constructed as thermally insulating composites, e.g., sandwich panels, multiple glazing, etc., and are thus also subject to the bimetallic effect, but they also do not have the same structure in terms of material, properties, etc. They are therefore not affected to the same extent by the individual factors of the bimetallic effect mentioned above as their surrounding composite profiles.

[0005] This leads to warping of windows, doors, and facade elements, impaired sealing functions, and, in the case of movable elements, difficulties in opening, closing, locking, and / or unlocking. The latter can subsequently lead to damage to the locking elements and / or their frame structures, as the user may force or even have to force opening or closing.

[0006] FR 3 099 199 A1 shows a composite construction according to the preamble of claim 1. Object of the invention

[0007] An object of the present invention is to provide a composite profile system for windows, doors and facade elements, especially for movable elements with large dimensions, which reliably prevents the bimetallic effect and thus largely prevents deformation, warping and generally the malfunctions caused thereby in terms of sealing, opening / closing and / or locking. General description of the invention

[0008] This object is achieved according to the invention by a composite construction for fixed and movable surface elements, such as windows, doors, panels and facade elements, in particular movable surface elements, wherein the composite construction comprises a flat filling, in particular a multiple glazing or a composite panel, with a plurality of first composite profiles as a frame, wherein the first composite profiles each have an outer profile, an inner profile and one or more first separating webs connecting the outer profile and inner profile, wherein the connection of the outer profile and the inner profile is equipped without shear in the longitudinal direction (e.g. by separating webs that are attached without shear or without shear). According to the invention, the outer profile is attached to an outer side of the edge region of the filling in the longitudinal direction in a first longitudinal section of at most 5% of the length of the outer profile in a shear-resistant manner to the filling, but without shear over the remaining length, e.g.the first longitudinal section represents between 0.1 and 4%, in particular between 1 and 3% of the length of the outer profile (at room temperature). Although the shear-resistant region can be located at any point along the length / longitudinal direction of the outer profile, it is preferably located at one end or in an end region of the outer profile in order to direct the temperature-induced expansion in one direction, wherein the end region extends at most over a distance of at most 10% of the length of the outer profile. In the case of (essentially) vertically mounted outer profiles, this is preferably the lower end or the lower end region. In the case of (essentially) horizontally mounted outer profiles, this shear-resistant region can be provided at / in the left or right end / end region.According to the invention, however, the inner profile is attached to the filling in a shear-resistant manner against an inner side of an edge region of the filling in the longitudinal direction in a second longitudinal section of at least the length of the first longitudinal section.

[0009] Particularly in larger composite structures, the bimetallic effect can lead to significant warping of the composite profiles. While a shear-free connection of the composite profiles using shear-free separating bars should, in theory, largely compensate for this, the inventors have found that in practice this is usually only partially successful, as these profiles are not used on their own, but rather as a frame for a generally completely differently constructed infill panel, which usually also represents multiple glazing with a considerable mass. Composite structures also generally feature tightly fitting sealing profiles between the infill panel and the profiles, which can sometimes lead to uncontrollable sticking. This can cause the shear-free separating bars to progressively shift against each other due to shearing, which can ultimately lead to permanent warping of the composite structure as a whole.This can not only lead to undesirable leaks, but particularly in the case of movable surface elements, this can result in them no longer being able to be opened, closed, or locked properly. In order to improve the forced interaction between the composite profile and the filling, and thus prevent gradual warping as best as possible and also achieve greater stability of the edging, the inventors determined that it would be advantageous to consider a type of controlled, shear-free connection between the edging profile and the filling. Better control would mean, on the one hand, that the sealing profiles would ideally not also have to serve to fix the filling to the profiles (or vice versa), i.e.They would not have to fit so tightly and would then be less prone to sticking and, on the other hand, even after months or years of repeated expansion and contraction due to daily, sometimes considerable, temperature fluctuations, the edging of the composite constructions would not warp.

[0010] The inventors have recognized that the consequences of the bimetallic effect on (large) surface elements can be successfully counteracted by the solution presented above.

[0011] Particularly in movable applications, such as sliding elements, the frequently desired size / height (and consequently a very heavy filling in the case of multiple glazing) means that the composite profile on the handle side is subjected to very heavy stress, mainly when closing due to central pulling. In such cases in particular, but in principle also if desired with fixed surface elements, the shear-resistant second longitudinal section can make up at least 25%, preferably at least 40% or more than 60% of the length of the inner profile (at room temperature) or even the entire length of the inner profile. If the entire length is not equipped with a shear-free structure, the shear-resistant second longitudinal section is advantageously distributed over several shear-resistant partial length sections, but over essentially the entire length of the inner profile.By providing such an extended shear-resistant equipment of the inner profile towards the filling, an even higher stability of the frame is achieved at the same time, in particular in terms of tensile strength perpendicular to the profile and parallel to the plane of the filling.

[0012] In the context of the invention, "inside" and "outside" are to be understood in such a way that "inside" is the side on which the smallest temperature fluctuations are expected over the period of use, whereas the term "outside" refers to the side opposite the surface of the surface element, i.e. the side subject to the greatest temperature differences.

[0013] The infill of the composite construction can be any known type of suitable flat material, e.g., a sandwich panel or multiple glazing. In the case of a sandwich panel, the aforementioned edge area can be the outer edge of the infill itself. In the case of multiple glazing, the edge area is preferably an additionally attached surround, e.g., in the form of a U-profile made of suitable plastic, which is optionally placed on the edge area of ​​the multiple glazing and preferably glued in place. Such a surround can be attached during the manufacture of the multiple glazing and thus also reliably protects the glazing from damage during transport to the installation site.

[0014] A shear-resistant connection can be achieved using suitable means and methods, e.g., by screwing, gluing, form-fitting, etc. It is preferably created using one or more shear-resistant supports, with the shear strength advantageously being achieved by the force-locking and / or form-locking of an appropriately shaped tongue on the shear-resistant support in a groove in the edge area of ​​the panel. A particularly suitable shear-resistant feature is a toothed arrangement of the appropriately shaped tongue. If a form-locking arrangement is (additionally) desired, the edge area of ​​the panel and / or the groove can have a corresponding counter-toothing arrangement.

[0015] A non-sliding or sliding connection is preferably created by means of one or more non-sliding brackets spaced apart in the longitudinal direction of the composite profile. The non-sliding bracket is connected to the panel, for example, by a sliding tongue guided in a groove in the panel's edge area. To improve the sliding function, the sliding tongue of the non-sliding bracket usually has a rounded cross-section.

[0016] Alternatively or additionally, a shear-resistant connection of the outer and inner profiles in the shear-resistant area can also be made simultaneously by a shear-resistant block attached to both profiles.

[0017] The invention further relates to a fixed or movable surface element, such as a window, a door, a panel or a facade element, in particular a movable surface element, comprising at least one composite construction as described above.

[0018] Preferably, such a composite construction is fixedly or movably mounted in or on a composite frame, wherein the composite frame comprises a plurality of second composite profiles, wherein the second composite profiles each have an outer shell, an inner shell and one or more second separating webs connecting the outer shell and inner shell.

[0019] In particular, the invention relates to movable surface elements such as, for example, a sliding element in a composite frame, wherein the sliding element has multiple glazing as a filling and wherein a number of rollers are arranged on the underside of the profile construction in a manner distributed along the length so that, in use, the sliding element is moved by guiding the rollers on a guide rail mounted on the lower part of the composite frame.

[0020] In the context of the invention, the first separating webs, the second separating webs, the shear-resistant block and / or the enclosure are preferably made of a material selected from the group consisting of polyamide; polyolefin, e.g., polypropylene; polyester, e.g., polyethylene terephthalate or polybutylene terephthalate; acrylonitrile butadiene styrene; polyvinyl chloride or mixtures or combinations thereof; if required or desired, the material is fiber-reinforced, e.g., glass-fiber-reinforced. Short description of the characters

Fig. 1a shows a cross-section of a conventional sliding element construction with a fixed frame and sliding element at approximately the same inside and outside temperatures. Fig. 1b shows a cross-section of the conventional sliding element construction of Fig. 1a with a large temperature difference between inside and outside. Fig. 2a and 2billustrate the effect of the bimetal effect in the sliding elements using a cross-section and a longitudinal section of the sliding element. Fig. 1a and 1b situations described. Fig. 3 shows a cross-section of an embodiment of the invention using the example of an improved sliding element construction. Fig. 4a and 4b illustrate by means of a cross-section and a longitudinal section of the embodiment from Fig. 3 the neutralization of the bimetallic effect according to the Fig. 2a and 2b situations described for conventional sliding elements. Fig. 5 shows a section similar Fig. 4b , with an additional shear-resistant design, whereby the cross-section shown on the left, in contrast to Fig. 4b bottom (Bottom) was guided through the sliding element.

[0022] Further details and advantages of the invention can be found in the following detailed description of possible embodiments of the invention with reference to the accompanying figures. Description of several embodiments of the invention

[0023] The figures in the appendix explain the problem of the bimetal effect described above using the example of a conventional sliding element and an embodiment of a sliding element according to the invention. However, it is emphasized again that the invention is not limited to application to sliding elements. The embodiments of the Fig. 3 , 4a and 4b can be used equally for fixed elements or other movable elements.

[0024] The Figures 1 and 2illustrate the bimetallic effect that can occur with conventional sliding elements 20 (state of the art), e.g. in the case of a glazed sliding door, whereby the problem is aggravated by high temperature differences between the outside and inside and larger dimensions of the sliding elements 20.

[0025] The Fig. 2ashows on the left a cross-section and on the right a longitudinal section through (or a plan view of) a conventional composite profile of a sliding element 20 at approximately the same temperatures on the inside and outside, in this case the vertical composite profile 20 towards the opening side of the sliding element. The composite profile 20 firmly / positively connects an outer profile 21 to an inner profile 22 via one or more insulating webs 23 designed as thermal separation, wherein the inner and outer profiles 21, 22 are usually made of metal, e.g. aluminum, and the insulating webs 23 are formed from a plastic material, possibly (glass) fiber reinforced, e.g. polyamide (PA), polyester (PET, PBT), polyolefin (PP), polyvinyl chloride (PVC) or other plastics (e.g. ABS, etc.).At approximately equal temperatures of the inner profile 22 (T inside ) and the outer profile 21 (T outside ) along the transverse direction y, each of the profiles 21, 22, as well as the separating web 23, has a length L in the longitudinal direction x.

[0026] In case of large temperature differences between the thermally separated outer and inner profiles, ie T outside > T inside , e.g. intensified in case of strong solar radiation on the outer profile, the outer profile 21 expands by an additional length Δx in the longitudinal direction x. As in Fig. 2b As shown, since the inner profile 22 does not expand (to the same extent) and all elements of the composite are rigidly / force-locked, the composite profile 20 bulges outwards due to the so-called bimetallic effect. However, the extent of the bulge Δy in the transverse direction can lead to the sliding element hitting the side part of the profile frame 10, as shown in Fig. 1bshown. This can not only lead to damage to the composite profile of the sliding element or the frame, but can in some cases prevent the sliding element (sliding door or sliding window) from being closed properly - intentionally or inadvertently. Such damage can also occur when opening on the opposite side if, when fully opened, the composite profile of the sliding element 20 can move at least partially into the opposite frame 10. It can also happen that, when the sliding element 20 is closed, the bimetallic effect means that the sliding element 20 cannot be opened or can only be opened with difficulty because the curved part becomes wedged in the frame profile 10. This can then also lead to scratches and abrasion marks on the sliding element 20 and / or the frame 10.

[0027] Fig. 1aconsequently shows a conventional closed sliding element 20 (with double glazing as filling 29) in its frame 10 with small temperature gradients (or no temperature difference) between the outer profile 21 and inner profile 22 of the composite profile of the sliding element 20. Both profiles 21, 22 have parts that can serve as handles 25, 26 for operating the sliding element. As already mentioned, both profiles 21, 22 are rigidly / positively connected by one or more separating webs 23, e.g. by rolling up or forming a collar, etc. These separating webs 23 enable the thermal insulation function of the composite profile 20 because they act as a thermal break and thus greatly reduce heat transfer by conduction from the inside to the outside or from the outside to the inside.

[0028] The frame 10, in which the sliding element 20 can move, is in principle constructed similarly to a composite profile with an outer frame part 11 and an inner frame part 12, which are thermally separated and non-positively connected by one or more separating webs 13. In order to ensure a wind and heat-tight closure when the sliding element 20 is closed, the frame has a U-shaped cross-section facing the sliding element, in which the outer region of the composite profile of the sliding element 20 is located when closed. The wind and heat-tight function can be supplemented by further aids 17, 18, such as brush, felt or rubber seals.

[0029] Fig. 1b shows the situation in the case of a large temperature difference between the outer and inner profiles 21, 22: T outside > T inside . The same reference numerals indicate the same elements as in Fig. 1a. The cross section here, again for example at half height of the sliding element 20, shows that the outwardly curved part of the sliding element 20 can no longer be easily guided into the U-shaped cross section of the frame 10 (see highlighted point in the Fig. 1b). In other words, the sliding element 20 will hit the frame with its outer profile 21 and possibly damage the frame or even prevent the sliding element 20 from closing completely. Locking (with locking means not shown here) of the sliding element 20 would therefore possibly even be impossible in this case, as long as the temperature difference between the outer and inner profiles 21, 22 is above a certain value. It may be necessary to wait until this temperature difference has decreased sufficiently, i.e. until Δy has decreased sufficiently, that the outer profile 21 of the sliding element 20 can be moved back into the U-shaped cross-section of the frame 10. However, damage that has already occurred to the frame 10 or to the composite profile of the sliding element 20 cannot be reversed by this.

[0030] In Fig. 3An embodiment of the invention is shown using the example of a sliding element 200 in a frame 100 in cross section, wherein the cross section is located, for example, approximately halfway up the frame 100.

[0031] The basic elements of the frame 100 and the sliding element 200, similar to those in the prior art, are also present here. The frame (second composite profile) 100 is formed by an outer shell 111 and an inner shell 112, which are rigidly / positively connected by one or more separating webs 113. Here, too, the frame 100 forms a U-shaped cross-section for receiving the outer edge of the sliding element 200 in the closed state. As in the prior art, wind and heat-sealing aids 117, 118, such as flexible sealing lips, are provided for sealing in the closed state. For both aesthetic and thermal engineering reasons, the U-shaped cross-section is preferably provided with a lining plastic profile 115, which is connected to the elements of the frame 100, for example, by slip-on or clip connections. This lining plastic profile 115 can additionally serve as a stop for the sliding element 200.In such cases, it may be expedient to provide the side of the lining plastic profile 115 facing the sliding element with a shock-absorbing lining 116, e.g., a flexible rubber or foam insert. It may also be expedient to provide (spring-loaded) support for the lining plastic profile 115 against the partition 113 located behind it.

[0032] The sliding element 200 is also an example of a glazed sliding door, e.g. with triple glazing as filling 290. The composite profile of the sliding element 200 also has an outer profile 221 and an inner profile 222, which are connected by one or more separating webs 213. In contrast to the conventional separating webs, however, separating webs are provided here which are either firmly connected to only one of the two outer and inner profiles 221, 222 and held on the other profile via a sliding profile, or, as in Fig. 3as an example, which are two (or more) parts, with one part being rigidly / positively connected to one of the two profiles and a second part being connected to the other profile, but these two parts are joined together so that they slide in the longitudinal direction of the profiles. By means of these, in themselves known, so-called shearless separating webs, a certain differential expansion between the outer and inner profiles 221, 222 is in principle possible. However, the use of such shearless separating webs in the connecting profiles of the sliding element frame not only results in a general reduction in the flexural rigidity of the connecting profiles, but also in the outer and inner profiles in each of the connecting profiles being able to move differently in the longitudinal direction x, as a result of which the sliding element frame can warp completely or partially.

[0033] In order to prevent the sliding element frame from warping, according to the invention, on the one hand the filling 290 of the sliding element 200, e.g. a triple glazing as in Fig. 3 shown, provided with a frame 261 and on the other hand, the inner profile 222 is connected to the frame 261 in a shear-resistant manner on a second length section SF2 (here as an example the sum of the four shown partial length sections SF2 i , ie SF2 a + SF2 b + SF2 c + SF2 d ) of length L, but the outer profile 221 is only connected to the frame 261 in a shear-resistant manner at one point, the first partial section SF1, particularly preferably at one end or an end region E of length L. On the rest of the length L, the outer profile 221 is always connected to the frame 261 in a shear-free manner. In the case of the vertically standing composite profile 200 of the Fig. 3the shear-resistant first longitudinal section SF1 is preferably located at or near the lower end, i.e. in the end region E. This ensures that the outer profile 221 can expand longitudinally sliding towards the filling 290 or the inner profile 222, but in a controlled manner only in one direction, namely upwards. If the inside and outside temperatures equalize again, both profiles 221, 222 are again in the same position relative to each other and to the filling 290. A progressive and uncontrolled displacement of the profiles 221, 222 relative to each other and / or relative to the filling 290 and consequently the warping of the sliding element frame is thus avoided. It should be pointed out again that the figures shown in the not necessarily to scale Figures 3 , 4a , 4b and 5The embodiments shown are, of course, only examples that fall within the scope of the claims. It is therefore obvious that, for example, the number and precise design of the shearless and shear-resistant mounts shown here are for illustrative purposes only.

[0034] Although not shown in the figures, the same principle applies to a vertical profile opposite the filling 290, which can therefore only expand in this direction. This ensures that the shear stress of the bimetallic effect has the same effect on both sides of the sliding element and that shearing of the sliding element frame does not occur. The horizontal composite profiles at the top and bottom edges of the sliding element can also be equipped in the same way, with the shear-resistant point (end area) on the outer profile preferably being located on the opening side.

[0035] A (partially) shear-resistant connection of the inner profile 222 to the enclosure 261 of the filling 290 can be achieved by any known method, e.g., by gluing, screwing, etc. The enclosure 261 is preferably connected, e.g., glued, to the filling 290 by suitable bonding agents 265 (in the second length section or the second partial length sections). A (partially) shear-free connection of the enclosed filling can be achieved by simply guiding it within a suitable boundary; however, movement transverse to the shear direction must then be largely prevented by other means, e.g., by locating the enclosed filling within a U-shaped cross-section of the composite profiles. In practice, however, such a "loose" connection would often be inadequate. Preferred shear-free connections can generally be connections with a tongue and groove.Preferably, the enclosure 261 has one or more grooves 263, 264 on each side facing the outside and inside in the longitudinal direction, wherein one or more shear-resistant holders 242 are attached to the inner profile 222 in the second longitudinal section SF2 or the second partial length sections SF2 i at several (regularly spaced) locations along the longitudinal direction.

[0036] In a preferred embodiment, this can be achieved by roughening or preferably toothing the tongue on the side facing the groove 264, i.e., by having a toothing 2422, such as prongs, hooks, or claws, which can connect to the material of the enclosure in the groove 264 in a force-fitting and shear-resistant manner. Alternatively or additionally, the base and / or the side walls of the groove 264 can have a corresponding counter-toothing to (additionally) enable shear resistance through positive locking. The one or more shear-resistant brackets 242 can be attached to the inner profile using suitable fastening means 2424, e.g., by screws.

[0037] On the opposite outer side, a shear-resistant connection between the outer profile 221 is provided only at a locally limited point in the longitudinal direction (first longitudinal section SF1), e.g., over one to several centimeters. For vertical composite profiles, this point is advantageously at the lower end. The locally limited shear-resistant support on this side and its fastening advantageously correspond to those on the inner side. Another locally limited shear-resistant connection of the outer profile 221 in the first longitudinal section SF1 with the enclosure 261 of the filling 290, as mentioned above, is of course also possible. The cross section in the Fig. 3(e.g., halfway up the sliding element 200), however, shows a non-thrust bracket 241 with a smooth (non-toothed) spring, the so-called sliding spring 2411, which is slidably mounted longitudinally in the groove 263. Similar to the opposite inner side, the non-thrust bracket 241 can extend over the entire length of the outer profile 221 not occupied by the locally limited non-thrust bracket 242 just described, or several non-thrust brackets 241 can be mounted at suitable (regularly spaced) locations along the longitudinal direction. The non-thrust brackets 241, the non-thrust brackets 242, and their fastening means 2413, 2424 can be made independently of metal, e.g., steel, aluminum, or aluminum alloys, or of (glass) fiber reinforced plastic, similar to those suitable for dividers.

[0038] The Fig. 4a and 4billustrate the invention presented here in the same situations as the prior art in Fig. 2a and 2b . In Fig. 4a and 4b The left side shows an embodiment of a (vertical) composite profile according to the invention in cross section with an outer profile 221 and an inner profile 222 which are connected by shearless separating webs. The respective right side shows a longitudinal section, in which Fig. 4athe temperature of the outer profile 221 is approximately the same as that of the inner profile 222. At the bottom, or in an end region E, both profiles are connected to the enclosure (not shown) of the filling by means of a shear-resistant bracket 242. The inner profile 222 further has further shear-resistant brackets 242 at regular intervals in the second partial length sections SF2 i along its entire length, whereas in the outer profile 221, all other brackets except in the end region E are shearless brackets 241. Since the temperature difference between inside and outside is small (T outside = T inside ), the bimetallic effect would occur as in Fig. 2a does not occur anyway: both profiles 221, 222 are the same length.

[0039] However, if this temperature difference increases as in Fig. 4bAs illustrated, the shear-free connection by the shear-free brackets 241 between the outer profile 221 and the enclosure (not shown) of the filling prevents the bimetallic effect from occurring. The outer profile 221 can expand in the longitudinal direction (Δx) without affecting the connection: the shear-free brackets 241 can move freely with respect to the enclosure in the longitudinal direction with the outer profile 221, regardless of any expansion of the enclosure, but due to the bottom shear-resistant bracket 242 on the outer profile 221, they can only move in the direction (see arrows in Fig. 4b) at the top (Top). The position of the non-sliding brackets 241 therefore changes progressively by a distance that increases with the temperature difference and the distance from the non-sliding bracket 242. If the non-sliding bracket 242 of the outer profile is located at the lower end, as is the case here, and the relative movement of the furthest non-sliding bracket consequently approaches the linear expansion Δx caused by the temperature difference without the assembly being subjected to warping, the sliding element 200 can be opened and closed easily and reliably, even with large temperature differences between the outer and inner profiles.

[0040] As mentioned, Fig. 5 a section similar Fig. 4b , with a different / additional shear-resistant connection of the construction, whereby the cross-section shown on the left, in contrast to Fig. 4bbottom (bottom) through the sliding element. Alternatively or in addition to the locally shear-free equipment of the outer profile 221 by means of a shear-resistant bracket 242 at the (lower) end of the composite profile as explained above, a shear-resistant block 280 can also be provided, which is fixed to both outer and inner profiles 221, 222, e.g. by means of suitable fastening means 281, such as screws, and thus reliably directs the expansion of the outer profile 221 in one direction (e.g. upwards) in the event of large temperature differences. This type of local shear-resistant connection can more reliably absorb the forces occurring due to the differential expansion in larger elements. In order not to significantly influence the thermal insulation of the composite locally, this shear-resistant block 280 is preferably made of plastic, e.g. like the (glass) fiber-reinforced polymers and poly blends commonly used for dividers.
