The methods - three dimension fabric - enforced laminates, and sparse fabric - enforced laminates, layer - enforced laminates ? to enhance the interlaminar toughness of fabric - reinforced laminates were discussed in this paper. the stitching method to enhance interlaminar toughness of stitched - laminates was mainly discussed in this paper based on our research and experiment. the middle - alkali glass fabric used as enforced - material with thickness of 0. 2mm, 3 section 600 deniner kevlar yarn is used as stitching thread in this research, which improved lock stitching way and different kinds of stitching mode were adopted
以提高層合板復合材料的層間斷裂韌性（能量釋放率）為目標，採用中堿玻璃布為增強材料，對疊層后的玻璃布，採用凱芙拉縫合線、改進的鎖型縫合方法、不同的縫合工藝進行了縫合；基體採用的是不飽和樹脂，固化劑為過氧化甲乙酮，促進劑為環烷酸鈷液；在室溫下採用真空輔助rtm （ resigntransfermolding ）成型固化方法，製作了不同縫合工藝的玻璃布增強復合材料層合板。The catalytic activity of ( hmbp ) 2ticl2was lower than - diketonate titanium catalysts. the catalytic activity of dinuclear - diketonate titanium catalysts was comparative to mononuclear ones. however, the dinuclear - diketonate titanium catalyst showed the synergism effect, for example, the lower catalyst concentration and the molar ratio of al to ti, the activity reached the maximum value at 80, the melting temperature of polymer was enhanced
2 -羥基苯酮鈦[ （ hmbp ） _ 2ticl _ 2 ]的催化活性低於-二酮鈦類催化劑；雙核催化劑在催化活性方面與對應單核催化劑相差不多，但在聚合規律上表現出與單核催化劑不同的雙核協同作用，如聚合所需的催化劑濃度、助催化劑甲基鋁氧烷mao量降低，活性在80時出現極值，熔點提高等，而且雙核催化劑是單活性中心催化劑。
