Abstract

本发明公开了可受轴向压缩或弯曲应力的合成材料管、柱、桅,它由经线与纬线不平衡的织物卷绕而成,从而使得加固纤维的主要部分与该结构件的纵向轴线平行。该管、柱和桅在一可压缩芯轴上卷绕而成,从而确保从管子中抽出芯轴时管子不受力或不产生微小裂缝。

Description

在一可压缩芯轴上卷绕不平衡织物而得的合成材料管件
许多结构件、特别是柱、杆或桅用钢制成，因此产生如下缺点：
a)重量重，在某些情况下很难放置；
b)容易受空气、水或土壤的腐蚀；
c)维护费用高。
为了克服这些缺点，用铝或合成材料制成这类结构件。在制作这类合成材料结构件时，一般使用卷绕粗丝的技术。
柱、杆或桅之类的结构件不仅应有良好的断裂强度，而且在受到趋于弯曲的运动时还应有很高的刚性。为此，合成结构件首先必须利用纤维的抗拉断裂和压缩强度，其次利用加固纤维的弯曲模量。因此，加固纤维的主要部分应与柱、杆或桅的轴线平行。
按照本发明，柱、杆、桅或梁之类的细长结构件由用环氧树脂、聚酯或乙烯基脂树脂之类热定形树脂浸渍的玻璃织物最好沿螺旋线卷绕而成。
按照本发明，这些织物的织纹不平衡，换句话说，长丝在纬线中的百分比比在经线中高。此外，其织纹可角变形，从而按照本发明，纬线长丝可与结构件的X-X’轴平行。
从下面的说明及其技术证实中可清楚看出本发明的这些高弯曲强度合成管的设计的创造性。
按照本发明，沿螺旋线卷绕一玻璃织物而制成一管，其中，经线/纬线比不平衡，c＜t，其中，c为纤维在经线中的百分比，t为纤维在纬线中的百分比。c的优选值为10-25％，t的优选值为90-75％；这一比例数使得可根据不同的直径/厚度比确保良好的抗径向变形。
按照本发明，该管由来回螺旋卷绕而成的相继各层构成。向前卷绕时，与纵向轴线的角度为B1=(90°-α)，向后卷绕时，与纵向轴线的角度B2=(90°+α)。
按照本发明，在进行卷绕时，织物最好有-α角斜度(见图1)，从而使纬线1与管的纵向轴线平行，经线2与圆周面3成α角；这一结构可提高弯曲模量。
按照本发明，在卷绕每层时，相邻两匝4、5的一部分重叠(见图2中的6)。为了避免局部过厚，相邻两匝之间的偏置宽度ι使得
γ=L/n
其中，L为该层的宽度，n为大于1的整数。
在本发明范围内，在进行螺旋卷绕时，各宽度可如图3中7所示邻接，也可交替(见图4)。宽度8和9在第一次向前卷绕时形成。宽度10和11在第一次向后卷绕时形成；宽度12和13在第二次向前卷绕时形成。这后一种卷绕方式可提高对层间剪切应力的阻力。
按照本发明，如卷绕的各匝邻接，相继各层最好偏置，以便减小由各宽度造成的不连续。例如，如以宽度L的各宽度相邻接螺旋卷绕成若干层q，每一层(向前卷绕+向后卷绕)的位置偏置一宽度空间K，使得
K=L/m
其中，m为大于1的整数，可能的话
m=q/r
r为整数(见图5)。
宽度14、15、16为第一次向前卷绕的宽度；17、18和19为第二次向前卷绕的宽度。
虽然优选的织物为玻璃织物，但在本发明范围内也可使用碳、芳酰胺或高强度聚乙烯织物。也可使用混合织物，例如玻璃加碳。
在本发明范围内，织物可预先用热定形树脂浸渍。
在本发明范围内，织物可预先用热塑树脂浸渍。
在本发明范围内，可在用热塑薄膜进行热压浸渍的同时卷绕织物。
在所生产的柱、杆或桅之类的结构件的厚度较厚、包括圆筒形部和结构件X-X’轴线上的不平衡加固纤维时，聚合反应后生成的很大的力会把该合成结构件夹紧在芯轴上，从而很难从芯轴上取下该结构件并在结构件中产生微小裂缝。
为了避免这一缺点，按照本发明，在芯轴上包上一光滑可压缩材料层后再在该可压缩芯轴上卷绕玻璃织物。
按照本发明，该材料选择成其可压缩性在卷绕织物的有限力的作用下只稍有变形，从而吸收合成结构件的收缩并把微小的夹紧力传到芯轴上，从而便于从芯轴上取下结构件。应选择摩擦系数低的材料。
按照本发明，该材料最好为表面光洁的闭孔聚乙烯泡沫塑料。
在本发明范围内，可使用具有上述特性的其他材料，例如柔性聚氨基甲酸酯泡沫塑料。
按照本发明，为了便于从芯轴上取下管子并不损坏其内表面，泡沫塑料上应涂萜烷薄膜。
在径向上有弯曲力作用的情况下，管子做成椭圆形(见图6)。这种管子比方说可用来建筑防波堤。
在本发明范围内，该管子可呈由本发明的两同心管20、21和一隔壁22构成的三明治结构(见图7)，该隔壁的材料的刚性比硬泡沫塑料、蜂窝结构、西印度轻木等好。这可使管子更轻、刚性更好。
在本发明范围内，为了在有弯力作用在主轴线上时提高刚性，内管可呈圆筒形，而外管呈椭圆形。
