  • Carbon fiber-reinforced cement mould
    Patent number: 4446091
    Abstract: A carbon fiber-reinforced cement mould is provided which is capable of being thermally cycled continually at temperatures up to 200.degree. C. Such mould is particularly suitable for casting or forming plastic articles which require heating up to 200.degree. C. to effect curing. Because the mould remains free from cracking and surface spalling during such thermal cycling, it can be used over and over again.
