    • The application discloses a variety of ways of making composites, particularly mats, in which a fabric layer and an uncured rubber layer are superimposed in a mould having opposed plates, and subjected to heat and pressure between the plates to cure the rubber and join it to the fabric. The fabric layer is preferably tufted, e.g. carpet. Preferred embodiments position an array of shaped fabric pieces over a surface of the rubber layer, leaving the rubber surface partly exposed. Methods and means are disclosed for protecting the fabric against the effects of moulding heat and also for keeping fabric pieces in position. These include positioning fabric pieces in recesses of a mould plate, providing heat-shield elements between the fabric pieces and the heated mould plate, providing movable pressure plates which bring the fabric pieces into contact against the rubber only when the mould is pressurised, and the use of spiked retaining formations to engage fabric pieces. Other methods disclosed relate to providing three-dimensional configuration on the fabric-covered surface, optionally with the rubber flowing through the fabric in a predetermined pattern, or with melting or fusing of a thermoplastic fabric. Characteristic moulding apparatus and characteristic composite products are aspects of the disclosure.
    • 该申请公开了制备复合材料,特别是垫的各种方法,其中织物层和未固化的橡胶层叠加在具有相对的板的模具中,并且在板之间经受热和压力以固化橡胶并将其连接到 面料。 织物层优选是簇状的,例如, 地毯。 优选的实施例将成形织物片的阵列定位在橡胶层的表面上,使橡胶表面部分露出。 公开了用于保护织物免受模制热的影响并且还用于将织物片保持在适当位置的方法和装置。 这些包括将织物片定位在模具板的凹槽中,在织物片和加热的模板之间提供隔热元件,提供可移动的压力板,只有当模具被加压时,织物才能与橡胶接触, 使用加标保持结构来接合织物。 所公开的其它方法涉及在织物覆盖的表面上提供三维结构,任选地以预定图案流过织物的橡胶,或者通过热塑性织物的熔化或熔融。 特征成型设备和特征复合产品是本公开的方面。

    • Plasma- treating small particles, such as carbon nanotubes, are disclosed. The technical aim is to achieve a controllable degree of treatment which is reasonably uniform in the mass of particles treated. The proposed method uses a low-pressure plasma (glow discharge) generated in a rotating treatment drum (4). The drum (4) has an axial electrode (3), internal vanes (44) and a sealable cover or lid (5). It can be evacuated via a port (52) having a particle -retaining filter. Process gas can be fed into it to maintain the plasma, e.g. through a fee opening (32) in the central electrode (3). An outer electrode may be provided as a separate surround (8) or as a conductive outer cylinder wall of the drum (4). Glow discharge is created along the central electrode, and the drum rotation speed adjusted so that the particles fall through the plasma zone. The drum (4) may have a port (51) through which fluid can be introduced to disperse the particles safely.
    • 公开了等离子体处理小颗粒,例如碳纳米管。 技术目的是实现可控程度的处理,这在处理颗粒的质量上是相当均匀的。 所提出的方法使用在旋转处理滚筒(4)中产生的低压等离子体(辉光放电)。 鼓(4)具有轴向电极(3),内部叶片(44)和可密封的盖或盖(5)。 可以通过具有颗粒保护过滤器的端口(52)将其抽真空。 可以将过程气体进料到其中以维持等离子体,例如, 通过在中心电极(3)中的开口(32)。 外部电极可以设置为单独的环绕(8)或作为滚筒(4)的导电外筒壁。 沿着中心电极产生辉光放电,并且调节转鼓旋转速度,使得颗粒落在等离子体区域中。 滚筒(4)可以具有端口(51),通过该端口可以引入流体以安全地分散颗粒。
