A numerical model capable of calculating the strength of 3D braided composites is developed, based on the micro-structure of 3D four-directional braided composites and the assumption of the braiding yarn with a helix configuration and ellipse cross-section. The strength of 3D braided composites have been predicted through a finite multiphase element method (FMEM). Comparison was conducted for those from the present model and experiment. The results are in good agreements with the experimental results in the previous literature. The influences of braiding angle on the strength are also studied.

Geometric Study

To estimate the precise mechanical properties of a three-dimensional (3D) braided composite, a geometric study is needed. Because of the complexity of the yarn paths inside the preform, the geometric modeling for 3D braided composites is always time consuming. In this paper, an efficient method, namely preform boundary reflection (PBR), is proposed for motion model construction in geometric studies. Furthermore, a CAD simulation system using novel combinations of parameters was developed for integral geometric descriptions of 3D braided preforms. Compared with the traditional method, the new method significantly simplifies the simulation process without affecting the precision of geometric structure. As a result, the structure design for composite preforms is effectively accelerated. The new method establishes a foundation for microstructure and mechanical properties analysis of preforms with complex geometric structures.

With the development of technology, composites are used more broadly, especially at different temperature. So it is very important to research the mechanical properties of composites at different temperature. Three dimensional braided composites are new composites with high performances, in which fiber-tows are interlacing in space with multi-direction and pass through the thickness to form a no-laminated and integrated structure. However researches on the mechanical properties of three dimensional braided composites are almost at room temperature. In this paper, the tensile and bending strengths of three dimensional braided composites (TR-30s carbon fiber/epoxy) at 23 oC and 150 oC are researched respectively. The results indicate that the effect of temperature on the tensile strength and bending strength of 3D braided composites is obviously different. The average tensile strength of 3D braided composites at 150 oC is almost the same as that at 23 oC. However the average bending strength of 3D braided composites at 150 oC is mush lower than that at 23 oC. This means that the effect of temperature on different mechanical properties is different and application temperature should be taken care of when 3D braided composites bear different kind of loads.
