摘要： Systems and methods are provided for enhancement of vacuum bagging processes for a composite part. One system includes dispensers configured to dispense materials onto a forming tool for a composite part, and a controller. The controller is able to identify a location for placing the composite part on the tool, and to direct the dispensers to lay up a laminate of constituent material for the composite part at the location. The controller is also able to direct the dispensers to spray vacuum bag material atop the laminate to form a vacuum bag that covers the laminate.

摘要： A reinforced fiber base material is placed on a forming die having a concave part and fixed to the forming die by at least a pair of fixing members disposed on either side of the concave part so as to form a gap between the reinforced fiber base material and a bottom surface of the concave part of the forming die. Subsequently, the reinforced fiber base material fixed to the forming die is covered by a bag film, a forming space that is formed between the forming die and the bag film is decompressed, and a matrix resin is allowed to flow inside the decompressed forming space. The matrix resin is then hardened so as to obtain a composite material in which the reinforced fiber base material and the matrix resin are integrally formed.

摘要： The present invention is a process for performing a planarization treatment of pressure-sensitive adhesive (PSA). The process includes positioning a first substrate onto a support surface of a planarization tool. The process further includes placing at least one layer of PSA onto the first substrate. The process further includes positioning a second substrate onto the layer(s) of PSA. The process further includes applying a pressure to the second substrate via a flexible membrane, said pressure being applied in a generally uniform, unidirectional and localized manner. Further, the applied pressure flattens the PSA between the first substrate and the second substrate for promoting suitability of the PSA for use in rigid-to-rigid lamination processes.

摘要： The invention relates to a process for the manufacture of composite products made of thermosetting plastic comprising a first pressure chamber (8) and a second pressure chamber (10). Each of the pressure chambers is provided with an elastically deformable chamber wall (12, 14), a mould configuration comprising at least one tool (16) with a mould chamber capable of accommodating a prepreg material (18). The pressure chambers are oriented with the elastically deformable chamber walls(12, 14) opposing one another, so that, when the press is operated with the mould configuration (16, 18) situated between the elastically deformable chamber walls (12, 14), the latter are at least partially in contact with one another with a pressing force (F) in a moulding stage. A pressure medium with a predetermined overpressure (Psteam) and temperature (T) is applicable inside the pressure chambers (8, 10), on the one hand in order to form a detail from the prepreg material (18) contained in the tool (16), and on the other hand in order to bring about hardening of the same. A favourable temperature increase as a function of the time is achievable in this way.
摘要翻译：本发明涉及一种制造由热塑性塑料制成的复合材料的方法，该复合产品包括第一压力室（8）和第二压力室（10）。每个压力室设置有可弹性变形的室壁（12,14），模具构造包括至少一个具有能够容纳预浸料材料（18）的模具室的工具（16）。压力室被定向成具有彼此相对的可弹性变形的室壁（12,14），使得当压力机以位于可弹性变形的室壁（12,14）之间的模具构型（16,18）操作时，后者在模制阶段中至少部分地具有压力（F）彼此接触。具有预定的超压（Psteam）和温度（T）的压力介质一方面可应用在压力室（8,10）内，以便从包含在工具（16）中的预浸料材料（18）形成细节），另一方面为了使其硬化。以这种方式可实现作为时间的函数的有利的温度升高。
