This work is devoted to the research of mechanical and strength properties of polymer composite material with short carbon fibers produced by injection molding technology. The material is PEEK90HMF20 with 20 % of carbon fibers mass fraction and based on polyether ether ketone (PEEK) polymer matrix. Mechanical and strength properties were researched on samples that had been cut from molded plates. A set of tension tests was performed and stress-strain diagrams of samples with different orientation in relation to the global direction of injection were obtained. Two-step homogenization procedure and pseudo-grains failure model were used to describe composite material behavior. The material model parameters were calibrated with experimental data by means of reverse-engineering procedure. Finite element simulation of tension tests was performed to check the quality of built model from the point of view of its ability to predict failure.

This paper is focus on two-Pass Deep Drawing Forming of conical axisymmetric parts, study on the finite element simulation and test of multi-Pass deep drawing part. It carry on the finite element analysis and calculation using the ANSYS/LS-DYNA software platform, analyzing the simulation results such as stress , strain distribution and formability by post-processing LSPOST software. It was done multi-Pass deep drawing test using a set of combined type mould. Based on the multi-Pass forming test by using a set of combined type mould, comparison of simulation and test data can be obtained through the forming limit diagram. The result of simulation and test is basically the same and both reflect the formability.

The One

A forming sequence of one-piece automobile steel wheels without welding was designed. In this forming process, the one-piece wheel was formed from a circular blank only by multi-stage stamping operations, and a deeply drawn cup was formed into the wheel. Two humps of the rim flange for fixing the tire were formed in the flaring and flanging stages. The humps of the rim in the opening and outer side were formed by buckling the inner flange of the rim, and by swelling the outer flange with an upper die having a short land, respectively. In addition, the number of stages was considerably reduced from 16 stages to only 9 stages by combining the deep drawing and ironing stages and by adding a holding die in the flaring stages. The forming sequence of the one-piece wheels was evaluated by both finite element simulation and miniature experiment.
