are as follows:(1)The starting reaction temperature of B/Pb 3 O 4 and B/BaCrO 4 delay compositions are independent of the proportion of the delay composition, it is about 415℃ and 780℃, But that is about 713℃ of B/CuO delay composition when B in the delay composition is in 3%~5%, and 662℃ when B is 7%~10%,(2)The reaction heat is augmenting with the augment of B in the boron series delay composition.

主要结论有:(1)B/Pb 3 O 4 和B/BaCrO 4延期药的反应起始温度分别在415℃和780℃左右,与配比没有关系;硼含量为3~5%,B/CuO延期药的反应起始温度在713℃左右,硼含量为7~10%,在662℃左右。(2)硼系延期药的反应热随硼含量的增大增大

The results show that when the porosity of sample was higher, compressure rate was higher and resilience rate was lower, however resilient rate of sample with higher porosity were increased notably when pressure was increased, and it tended to accord with of sample with lower porosity. The friction coefficient was higher when porosity of paper-based friction material was higher, and the friction coefficient tended to reduce and stabilize when braking pressure was increased. The friction coefficient of sample with high porosity tended to reduce and stabilize in continuous braking cycles.

The fabrication of fibers was attempted. The copolymers, the copolymers containing MOCT and the copolymer films containing MOCT were characterized by using Fourier Transform Infrared Spectroscopy, Scanning Electron Microscopy, Differential Scanning Calorimetry, Thermogravimetric Analyzer and X-ray Diffraction etc. The conclusions were summarized as following,1. The AN/MMA copolymers were testified that copolymerization of most AN and MMA occurred and the ratio of AN and MMA in copolymer was less than the ratio of monomers. With the increase of the contents of MMA, the viscosity of copolymer solution, molecular weight and decomposition temperature of copolymers increase.
