摘要:
A method of manufacturing a glass fibre reinforced structural composite article, said method comprising the steps of spraying a mechanically blended polyester foam into a mould whilst stimultaneously introducing chopped glass fibre. The mechanically blended polyester foam is foamed ulilising a gas, and said polyester foam includes a polyester resin that has a viscosity in the range of 12000-15000 cP (Brookfield LVT sp. 4/12 rpm). An article manufactured by this method can be made without the necessity of rolling to remove air bubbles, and has a density in the range of 0.6 to 0.8 g/cm3.
摘要(中):
一种制造玻璃纤维增强结构复合制品的方法,所述方法包括以下步骤:将机械混合的聚酯泡沫喷涂到模具中同时引入短切的玻璃纤维。 机械混合的聚酯泡沫是气体发泡的,所述聚酯泡沫包括粘度在12000-15000cP(Brookfield LVT sp。4/12 rpm)的聚酯树脂。 通过该方法制造的制品可以在不需要轧制的情况下制成,以除去气泡,并且其密度在0.6至0.8g / cm 3的范围内。
