Background

The continuous long fiber reinforced resin-based composite material products are increasingly widely applied, and correspondingly, the performance detection requirement of raw materials for the composite material products is also increasing, wherein the tensile property of the fiber multifilaments is used as a main detection index of the fiber performance and is used in the conventional detection process of the raw materials. In the test process, the resin infiltrated on the fiber is solidified, uneven stress borne by the monofilaments can be transferred to a certain degree, if the monofilaments are dispersed and not integrated into a bundle, the resin is difficult to diffuse redundant stress in time, so that the stress is concentrated locally, the local monofilaments break firstly, and the integral test value is influenced. Therefore, when the fiber tensile test piece is prepared, the cross section of the fiber is close to a perfect circle, so that the resin can conduct and disperse local stress when stressed, and the breaking strength of the fiber multifilament is improved. However, the cross section of the continuous fiber of the existing filament nozzle is in a fusiform shape with a longer axial length.
