The effects of annealing and loading rate on the fracture behavior of poly (lactic acid) were investigated. Mode I fracture toughness values, K IC and GIC, were evaluated under quasi-static and impact loadings. It was shown that the multiple craze formation resulted in the high KIC and GIC of the quenched-static, and the supression of the crazing lowered the toughness at impact loading rate. The results show that for the annealed condition, microcracking at the spherulite interfaces can be responsible for the increase in the toughness.
