研究结果表明：随着缝纫密度、缝纫线直径、最大纤维偏转角和缝纫变形区宽度的增加，缝纫复合材料层合板面内等效模量逐渐降低，最大降幅一般在5%左右；缝纫复合材料层合板的拉伸强度随缝纫针距的增加而增大，随缝纫行距的增加而降低，因此缝纫密度对拉伸强度的影响程度要看具体的缝纫针距和行距。

The results show that the gabion meshes present good tensile characteristics in the event of the rupture of the meshes. The larger-diameter gabion mesh shows a better mechanical performance, and the mechanical performance of 80RE geogrid is superior to that of 70RE geogrid. The revised relationship curves between the tension per unit width and unit elongation also present elastic stage, yield stage and strength stage. The constraint deformation of reinforcement is influenced by factors such as secant modulus of materials, stress levels, and the length of reinforcement in active area and stable area.

The results show that: the tensile strength, flexural strength and flexural modulus increase by about 10.4%, 62.1% and 122.3% respectively when the mass fraction of the aluminum powder increases from 0 to 50%, while elongation at break and impact strength decrease by about 65.0 and 74.4% respectively; the tensile strength, elongation at break and impact strength all increase with decreasing the particle sizes of the aluminum powders.b Nylon-12 coated metal powders for the indirect SLS process were prepared by the dissolution precipitation process. The coated powders have only 1.0 wt% nylon-12, and their SLS green parts have sufficient strength for features as small as 1.0 mm to be built and post-processed and high dimensional accuracy. The green parts were subjected to the post processing processes including binder decomposition and infiltration of epoxy resin, and then the metal/polymer composite parts with relatively high strength and accuracy were formed.At present, micron-scale inorganic fillers have been widely used to reinforce nylon SLS parts.
