壓路機卷簾天窗組件用復合導軌
雷諾,威巴斯托,AARK Shapers和Polycope開發了一個滾動盲天窗模塊的復合導軌,用于雷諾的兩種多用途車輛(MPV)的全景車頂,稱為Scenic和Grand Scenic。

在由塑料工程師協會(SPE)主辦的第18屆年度汽車復合材料會議和展覽(ACCE)上,由汽車制造商雷諾集團(Bouloene-Billancourt,法國)、級Webasto SC(Les Ch Telliers-Chateaumur,法國)、工具制造商和模塑公司AARK-Shapers(法國La SéGuinière)和樹脂供應商Polycope Polymers(荷蘭Geleen)組成的團隊贏得了會議與會者選擇的具創新性的組合部件的選擇獎。贏得提名的是雷諾(Renault)旗下兩款多用途汽車(MPV)-Scenic和Grand Scenic-的全景車頂(全景車頂)上的條組合式導軌。自2016年以來,這兩款車型已投入商業生產。威巴斯托和波利奧的代表在閉幕式上接受了這一獎項,并共同提交了一份關于導軌設計和開發的技術論文。
從鋁型材向熱塑性復合材料的轉變降低了零件重量和工作噪音,簡化了車輛裝配線上的天窗結構和安裝,降低了成本,增加了乘客車廂的頂空。Webasto設計了注塑模Rails,使其包括高水平的功能集成,同時減少了零件數量、裝配操作和制造時間、成本和復雜性。XIRAN SGH30EB是聚苯乙烯馬來酸酐和丙烯腈丁二烯苯乙烯(GR-SMA/ABS)的玻璃纖維增強共聚物,對其進行了優化,既保證了用于將玻璃固定在模子上的聚氨酯膠粘劑的高粘結強度,又保證了模組與白車身(BIW)屋面結構的高尺寸穩定性,并保證了壓路機的順利運行所需的高維穩定性。AARK-Shapers的巧妙工具使天窗模組的8個GR-SMA/ABS復合部件能夠在一個家庭工具中模制,該工具還具有模塊化塊,既允許風景區(五座)和大風景區(七座)鋼軌在同一工具中模制,而無需使用昂貴的工具動作(幻燈片)或單獨的工具。每根鋼軌用兩塊模壓成型,拆卸后用超聲波焊接。

在雷諾的裝配廠,新的天窗系統,包括壓路機盲,到達完全組裝和預測試作為一個整體的單位,是機器人連接到屋頂,消除了二至三個組裝步驟,并允許重新分配操作員。初始系統成本降低約20%。然而,新的模塊有較少的部件,預計將減少長期保修成本,因為較低的部件/百萬(PPM)缺陷和更高的質量已經在雷諾。另一個好處是,Z軸元素棧減少了≈13毫米,因為整個模塊是直接粘合到車身白色(Biw)屋頂結構,而不是傳統的兩到三步的過程,其中的鋼軌是用螺絲緊固到BIW,然后模塊是固定在軌道上。這不僅為工人在裝配線上提供了更多的工作空間,而且在車輛使用期間也給了較高的車輛乘員更多的車頂空間。另外,在遮陽過程中不需要油脂,噪音/振動/粗糙度(NVH)降低。和鋁一樣,復合鋼軌是完全可循環利用的,但初生產它們所需的能源較少,并且在車輛壽命結束時再循環使用。

Renault, Webasto, AARK Shapers and Polyscope developed composite guide rails on a rollerblind sunroof module for the panoramic roof on two models of multipurpose vehicles (MPVs) from Renault called the Scenic and the Grand Scenic.
Renault-Webasto-AARK Shapers-Polyscope team wins 2018 SPE-ACCE people’s choice award for composite sunroof rails
At the 18th-annual Automotive Composites Conference & Exhibition (ACCE) sponsored by the Society of Plastics Engineers (SPE), a team comprised of automaker Groupe Renault (Boulogne-Billancourt, France), tier one Webasto SC (Les Ch?telliers-Chateaumur, France), toolmaker and molder AARK-Shapers (La Séguinière, France), and resin supplier Polyscope Polymers (Geleen, The Netherlands) won the event’s People’s Choice award for the most innovative composite part chosen by conference attendees. The winning nomination was for the first composite guide rails on a rollerblind sunroof module for the panoramic roof on two models of multipurpose vehicles (MPVs) from Renault called the Scenic and the Grand Scenic and have been in commercial production since 2016. Representatives from Webasto and Polyscope accepted the award during closing ceremonies and also co-presented a technical paper on design and development of the guide rails.
The move from aluminium extrusions to thermoplastic composite lowered part weight and operating noise, simplified sunroof construction and installation on the vehicle assembly line, reduced costs, and increased headspace in the passenger compartment. Webasto engineered the injection molded rails to include a high level of functional integration while simultaneously reducing part count, assembly operations, and manufacturing time, cost, and complexity. XIRAN SGH30EB — a fiberglass-reinforced copolymer of styrene maleic anhydride and acrylonitrile butadiene styrene (GR-SMA/ABS) from Polyscope — was optimized both to ensure high bond strength to the polyurethane adhesive used to mount the glass to the module and the module to the body-in-white (BIW) roof structure, and to ensure high dimensional stability critical for smooth operation of the rollerblind. Clever tooling by AARK-Shapers enabled eight GR-SMA/ABS composite parts for the sunroof module to be molded in a family tool that also features modular blocks allowing both Scenic (five-seater) and Grand Scenic (seven-seater) rails to be molded in the same tool without using costly tooling action (slides) or separate tools. Each rail was molded in two pieces and ultrasonically welded after demolding.
Composite guide rails for rollerblind sunroof module
At Renault’s assembly plant, the new sunroof system, including the rollerblind, arrives fully assembled and pretested as a one-piece unit that is robotically bonded to the roof, eliminating two-to-three assembly steps and allowing an operator to be reassigned. The initial system cost reduction is around 20%. However, the new module has fewer parts and is expected to reduce long-term warranty costs as indicated by lower parts/million (PPM) defects and higher quality already seen at Renault. Another benefit is that a Z-axis element-stack reduction of ≈13 mm was achieved because the whole module is adhesively bonded directly to the body-in-white (BIW) roof structure instead of the conventional two-to-three-step process wher rails are fastened with screws to the BIW and the module is then fastened to the rails. This not only provides more working space on the assembly line for workers, but also gives taller vehicle occupants more headspace during vehicle use. Additionally, no grease was needed and noise/vibration/harshness (NVH) was reduced during sunshade operation. Like aluminium, the composite rails are fully recyclable, but less energy is needed to produce them initially and to recycle them at end of vehicle life.
