Plastic heat expansion variation method - using plastic combined with textile of aligned glass fibres passing right through it

摘要

Plastic layer is combined with textile comprising aligned glass fibres passing right through it. The fibres can run in two intersecting directions or more, and there can be two textile layers, on opposite sides of the plastic. They can be combined with the plastic, being compressed with it while it is still in the plastic state. The textile can be impregnated with plastic compatible with that of the layer, and contain roughly 65% by weight of glass fibres.
