一、前 言 玻璃钢制品具有整体成型的特点。但是对于大型产品和复杂制品,是无法采用一次整体成型的,总是做成预制件,然后将预制件连接组合成一个整体。因此,对于大型结构物,如船、桥梁、房屋等,预制件的连接将是一个重要环节。 当前,玻璃钢的连接方式分为三大类:胶接、机械连接、胶接与机械连接并用。无论采用哪种连接方式,通常都会发生应力集中现象,而玻璃钢又属脆性材料,其应力集中的程度一 First, the foreword FRP products with the overall shape of the characteristics. However, for large products and complex products, it is impossible to use one-time integral molding, always making prefabricated parts and then connecting the prefabricated parts into a whole. Therefore, for large structures such as ships, bridges, houses, etc., prefabrication will be an important link. At present, the FRP connection is divided into three categories: glue, mechanical connection, plastic and mechanical connection and use. No matter what kind of connections, stress concentration usually occurs, and FRP is a brittle material, the degree of stress concentration of a
