As always, it was very well written!
The main role of the resin matrix of z-pins is to keep the fiber bundle rigid, so that it can be implanted into the through thickness of the laminates. As for 【也可用With regard to】toughening effect, compared with z-pin(a composite of fiber bundle and resin matrix), fiber bundle without resin has a larger contact area and bonded 【bonds】 better with laminate. Besides, less initial crack is caused by the thermal residual stresses. The presence of the resin matrix of z-pin has little beneficial into 【has little beneficial effect/impact on】 the interface between z-pin and laminates. It will be ideal if such kind of resin matrix can be found, 【.上句完结于此】in 【In重开始一句】 the implantation process, the resin can transfer load and keep the fiber bundle rigid; after the z-pin is implanted into the laminates, the resin can be removed, and only the fiber bundle remains. Thereafter, the interface between z-pin and laminates is converted into the interface between the fiber bundles and the matrix of the laminates, which will improve the interfacial properties, and reduce the thermal residual stresses both to a large extent 【to a large extent in both cases】. For this kind of z-pins, the most required mechanical performance is to have good piercing properties so that it can be implanted into the laminates smoothly.
As for toughening effect, compared with z-pin(a composite of fiber bundle and resin matrix), fiber bundle without resin has a larger contact area and bonded better with laminate. 可改为：
With regard to the toughening effect, fiber bundle without resin has a larger contact area and bonds better with laminate as compared with z-pin(a composite of fiber bundle and resin matrix). |
