2 Transverse impact of spherical projectile onto clamped fabric
Single plies of rectangular fabric strips were ¯rmly clamped along two opposite edges and shot with spherical steel projectiles.The fabric used in the impact test is plain-woven Hexcel-Schwebel high performance fabric style 706.It is a neat plain-woven Kevlar KM2°R fabric with 600 denier yarns (the yarn linear density is therefore 0.067 g/m).The fabric thickness is 0.236 mm
and area density is 180 g/m2.There are 34 yarns per inch in the fabric for both the warp direction and the weft direction.Rectangular fabric specimens have a dimension of 50.8 mm £ 92.3 mm.The two shorter edges of the fabric specimens were clamped between a pair of rigid aluminum frames.Asshow in Fig.1 (a),the aluminum frame has a square geometry with a 152
mm outer dimension and a 50.8 mm inner opening.The clamping faces of the aluminum frames were knurled so that the fabric specimen can be effectively clamped,with no or

答案

2球状子弹头的横向冲击被夹紧的织品
一层长方形织品小条¯rmly沿二个相反边缘被夹紧了并且用球状钢子弹头射击了.用于冲击试验的织品是简单被编织的Hexcel-Schwebel高性能织品样式706.它是一种整洁的简单被编织的凯夫拉尔KM2°R织品与600团旦尼尔毛线因此(毛线线性密度是0.067 g/m).织品厚度是0.236毫米
,并且区域密度是180 g/m2.有每英寸34团毛线在织品为经线方向和纬纱方向.长方形织品标本有维度50.8毫米£ 92.3毫米.织品标本的二个更短的边缘被夹紧了在一个对刚性铝框架之间.Asshow在.1 (a),铝框架有方形的几何以一个152
毫米外面维度和一个50.8毫米内在开头.铝框架的夹紧的面孔是隆起的,以便织品标本可以有效地被夹紧,没有或一点动力传递损耗在冲击期间.长方形织品标本的二个更短的边缘均匀地被投入了在对铝框架之间紧紧然后夹紧了以八个对离开50.8毫米的一个方形的冲击面积螺栓和坚果汇编.被装配的铝框架使用二个重的螺栓登上了在气体自动枪范围
如所显示.1 (b)和准备好冲击试验.
