Abstract
In this paper, we have studied the hot forming process of composites made by polylactic acid (PLA) and corn straw fiber. In order to obtain the composite cushioning material with ideal density and expansion ratio, the parameters of processing was optimized. It showed that the optimum condition as follows: the hot-press time was 5min, the pressure was 15MPa and the temperature was 200°C. The structure of the composite was characterized by FTIR.
