説明

To solve the fundamental problems for volume change and internal stress during cure, the volume change, the glass transition temperature, the expansion coefficient and the young's modulus were measured during cure.<BR>These value changed according to the 1st. order reaction.<BR>The following experimental equation is found:<BR>Were:β: ratio of volume shrinkage at curing and cooling.β1: volume shrinkage with chemical reaction for cured resin.β2: Tq. of cured resin. k: reaction velocity.β0 expansion coefficient of liq. epoxy resin.β'; expansion coefficient below Tq.β∞: expansion coefficient above Tq. C1: curing temperature. C2: room temperature (arbitrary temperature bellow Tq). t: reaction time.
