比較ppffioc和ppcacos二體系的增韌行為，發現加入eoc和cacos都能增韌pp ，首次驗證了新型彈性體eoc和無機剛性粒子cacos增韌pp的機理符合wu氏逾滲理論，二體系發生脆韌轉變的基本條件是基體帶厚度l小於臨界基體帶厚度人（ 。The results revealed that the essential condition occurring brittle - tough transition in such ternary system was l ? lc ( ? 0. 095 ? m ), and the effect of above factors on the impact behavior followed percolation mechanism which indicated that it was some reasonable using lc as single parameter criterion of brittle - tough transition of pp / eoc / caco3 composites. the micro - deformation model at different dispersing morphology was then proposed
首次將聚合物復合材料脆韌轉變機理的定量化研究從二元體系拓寬到三元體系，對ppffioc aco3體系的配方進行設計，制備得到高剛性高韌性低成本的聚丙烯復合材料， eoc和cvco3的體積份數之和為25v （其中彈性體相為10v 。First of all, in order to obtain the nonlinear ice force, the first part concentrates on the research for the physical property of ice. especially on the ductile to brittle transition mechanism
對海冰的非線性物理力學性質進行了總結，特別關注了海冰破壞的韌脆轉變機制以及微裂紋演變對海冰性質的影響。After pretorsion the successor tensile yield limit and strength limit both improved very highly, but the trend of the increase of the strength limit was suspended till the pretorsional capacity reached 17, when the pretorsional capacity was greater than17 ( prestrain value was 81. 19 % of total strain ), the successor strength limit rapid failed and approached the yield limit. this illustrate the a3 steel specimen translate from plasticity into friability after pretorsion strengthen. when the specimen was operated by tension - torsion action, the yield limit had very large improved, but the strength limit changed very little. furthermore, the trend of the increase of the strength limit was suspended till the pretension capacity reached 0. 25 ( prestrain value was 66. 93 % of total strain )
A3鋼試件在預扭轉后，后繼拉伸屈服極限和強度極限均有很大提高，但強度極限的增大趨勢到預扭轉量為17為止，預扭轉量大於17 （預應變值為總應變的81 . 19 ）后強度極限迅速下降，與其屈服極限接近，這說明a3鋼試件經預扭轉強化后逐漸由塑性轉化為脆性。該預應變值為a3鋼試件的韌脆轉變點。 a3鋼試件在拉伸-扭轉作用下，屈服極限有很大提高，但強度極限沒有多大改變，而且，屈服極限的增大趨勢到預拉伸量為0 . 25應變（預應變量為總應變量的66 . 93 ）后就不再增加。Toughness of cs rod crosslinked with glutaraldehyde increased drastically, and the modified rod showed tough rupture. 4
