The invention relates to the field of novel material preparation, and discloses a profile tension and compression process adopting a PMI foam sandwich. According to the profile tension and compressionprocess adopting the PMI foam sandwich, the fiber reinforced profile is prepared while the PMI foam sandwich is filled into the fiber reinforced profile. In the same method and the step, the PMI foamsandwich material and the profile of the fiber reinforced material have a very good connection effect. The problem in the prior art is effectively solved, a very good connection effect of the foam sandwich material and skin material can be achieved, the non-adhesive layer helps to meet a weight reduction requirement of products, and the non-joint is beneficial to the uniform bearing capability ofthe hollow profile and to improving the overall stability; the material which cannot tolerate the temperature of high-temperature-foaming of the PMI foam can be used as the skin, so that the selectivity of the material is expa
