Abstract : The Charpy impact strength of thirteen unreinforced plastics (and one thermoset) has been measured over the temperature range -50 to +80C. Energy to fracture/temperature profiles have been produced showing the effects of temperature and changes in notch geometry. The effect of transitions below the glass transition have been considered briefly in one case.
