俺混過的公司的產品--預浸料產品模具用環氧樹脂--超高Tg+超好機械性能+超高尺寸穩定性。
絕對性能優異,但是價格高的一蹋糊涂,看了跑路。
預熱一下,等待同學們把帖子頂起來啊

耐高溫的環氧樹脂,一般都需要后處理過程,不知碰上葉片這么大的模具,怎么加熱[s:3]--模具沒有做好,應該沒有加熱系統吧?[s:5]

前面的設計階段要做的事情, 一般會列出需要事先作結構分析的項以靜態結構分析和熱多物理耦合分析為主:
Mould fabrication is preceded by several FEA analyses to optimise final performance. The structural analysis optimises the response of the mould and its components during the heat curing regimes encountered in rapid cycle blade manufacture, contributing to optimum layout of heating zones whilst also managing energy conservation. Beforehand modelling analysis helps mold shells match blade countour and mould movement, taking account of the specific blade laminate construction, thus unwanted stresses and potential mould repairs are minimised.
Structural analysis determines the optimum dimensions, stiffness and weight of the mould steel frame resulting in easier handling and laminate lay-up and minimal mould distortion.
