The surface morphology; chemical structure; degree of crystallinity and thermal properties of Para-aramid fibrid were studied by using SEM; AFM; FT-IR; XRD and TGA. This paper was used to offer an experimental foundation for promoting its extensive use as one kind of composite reinforced materials. Results indicated that Para-aramid fibrid was non-granular and small-sized; it had a fiber or film looking; roughness surface; supple shape. The fiber had a secondary amide structure; and its crystallinity was 28.55 percent. As a result; it contained amounts of amorphous compositions; and the crystalline size in fibers was tiny. The initial decomposition temperature of fiber was 490°C; TG10%; was; 550°C; thus demonstrated its stable molecular chain structure and excellent thermal properties;
