    • A method of making a composite panel from two substantially similar panel skins (40, 42) and an edging (48), is disclosed. The first panel skin (40), is made in a mould from a first composition comprising a thermosetting resin, a catalyst for the thermosetting resin and inorganic filler particles. On this layer is placed a layer of a fibrous reinforcing material wetted with a second composition comprising a thermosetting resin and a catalyst for the thermosetting resin. Before the thermosetting resin in the second composition has set, the edging (48) is placed all around the edge of the first panel skin (40). The thermosetting resin in the second composition then sets to form a combination of the first panel skin (40) with the edging (48) attached thereto. The second panel skin (42) is then formed in the same manner as the first panel skin (40) and before the thermosetting resin in the second composition is set, the combination of the first panel skin (40) and the edging (48) is placed on the second panel skin (42) with the edging (48) in contact with the second panel skin (42). The thermosetting resin is then allowed to set to form an intermediate panel from the second panel skin (42) and the combination. The intermediate panel includes a cavity defined by the first and second panel skins (40, 42) separated by the edging (48), and this cavity is filled with a polyurethane foam (50) to form the composite panel.
    • 公开了由两个基本上类似的面板表皮(40,42)和边缘(48)制造复合面板的方法。 第一面板蒙皮(40)由包含热固性树脂,用于热固性树脂的催化剂和无机填料颗粒的第一组合物在模具中制成。 在该层上放置一层用包含热固性树脂和用于热固性树脂的催化剂的第二组合物润湿的纤维增强材料。 在第二组合物中的热固性树脂已固化之前,边缘(48)全部放置在第一面板蒙皮(40)的边缘周围。 第二组合物中的热固性树脂然后凝固以形成第一面板蒙皮(40)与附着于其上的镶边(48)的组合。 然后以与第一面板蒙皮(40)相同的方式形成第二面板蒙皮(42),并且在第二组合物中的热固性树脂凝固之前,第一面板蒙皮(40)和边缘(48) 放置在第二面板蒙皮(42)上,边缘(48)与第二面板蒙皮(42)接触。 然后允许热固性树脂凝固以形成来自第二面板蒙皮(42)和组合的中间面板。 中间板包括由被边缘(48)分开的第一和第二板皮(40,42)限定的空腔,并且该空腔填充有聚氨酯泡沫(50)以形成复合板。
