    摘要： Disclosed are a manufacturing method for a support substrate (14), and an LED display device. The support substrate (14) is made of a carbon fibre material. The manufacturing method for the support substrate (14) comprises the steps of: S1: preparing a carbon fibre prepreg fabric; S2: preparing a support substrate (14) sheet; S3: pre-forming; and S4: molding. The LED display device comprises at least one cellular LED display screen (1), and the cellular LED display screen (1) comprises a support substrate (14) manufactured using the abovementioned method. The cellular LED display screen (1) comprises an LED display module, the support substrate (14), a control plate and a back cover (16). The LED display module comprises a face guard (11), a lamp plate (12) and a backing plate (13). The support substrate (14) is arranged between the LED display module and the control plate in a sandwich manner; the back cover (16) is connected to the support substrate (14) through studs; and the adjacent cellular LED display screens (1) are assembled by connecting bases (142) and locating pins (143) arranged at the four corners of the support substrate (14). The LED display device is simple in structure, light and thin, has a strong bearing capacity, and is convenient to install and low in transportation costs.

    摘要： An integral composite rocket motor nozzle. The novel nozzle includes a first layer of a first reinforcement material, a second layer of a second reinforcement material, and a common matrix material surrounding the first and second reinforcement materials such that the reinforcement materials and matrix material form a single integral composite structure. In an illustrative embodiment, the first reinforcement material includes graphite fibers for providing structural support, and the second reinforcement material includes glass or quartz fibers for providing thermal insulation on a first side of the first layer. The nozzle may also include a third layer of a third reinforcement material for providing thermal insulation on a second side of the first layer. In a preferred embodiment, the first layer is shaped to form an integrated dome and nozzle structure.
