โœฆ Synopsis

The fracture toughness of three different glassy carbons heat treated at 1000,2000 and 3000ยฐC was measured at temperatures between 25 and 750ยฐC. Young's elastic modulus varies inversely with measurement temperatures, whereas fracture toughness varies directly. Fracture characteristics of the glassy carbons are compared with those of float glass and graphites.

An evaluation of variations in the flexural strength of graphite determined in four-point bending tests has shown geometrical factors to have substantial influences on the measurement. Among the factors evaluated were the specimen cross-sectional geometry, ratio of load/support span to specimen thic

The specific heat of glassy carbon was investigated in the temperature range of 0\*44-4\*5"K. The specific heat follows a relation C = aT3+ yT, with y going through a ma~mum and a! increasing with increase in heattreatment temperature. On the average the cubic specific heat term is about the same as
