连续板成型工艺是在连续成型机组上使不饱和聚酯树脂浸润玻璃纤维,然后通过模板加热定型固化得到特定截面形状的连续板材的一种工艺。具体可以是,连续玻璃纤维无捻粗纱经过切刀被切割成定长的纤维均匀撒落到树脂层上(或短切纤维毡铺放在树脂层上),进行浸胶挤胶加热;上部再放一层防老化膜,这样上、下薄膜之间的玻璃纤维与树脂层组成一个夹层带。夹层带通过不同的截面模板成形,然后进入固化炉固化定型。之后再对定型后的玻璃钢板材进行切割。
FRP板材与其他材质板相比,具有轻质、高强、抗冲击性好等特点,尤其是它具有独特的透光性及断面可设计性。

Continuous panel moulding process is to impregnate unsaturated polyster resin with fiberglass through continuous moulding sets, and then continuous panel shall be obtained with specific cross shape through heating, moulding and curing of the template. Specifically, continuous fiberglass roving cut into fixed-length fiber through the cutter shall be scattered on resin layers (or the chopped fiber mat shall be applied on resin layer) and impregnated with gum for heating; an anti-ageing film shall be placed on the upper part so that a sandwich zone can be formed between fiberglass and resin layer of upper and lower layers. The sandwich zone can be shaped through different cross templates and placed into the curing oven for shape fixation. Then the shaped glass reinforced plastics panel shall be cut.
Compared with other panels, FRP panel has such advantages as light weight, high intensity and excellent impact resistance, especially the unique light-transmitting performance and section designability.
