Identify the horizontal and vertical of mother buckle (collar) material.Cut out specimen, described sample has the 70mm (length) of the 50mm (width) * transversely on being of a size of vertically.Use two-sided tape that collar sample is installed to steel plate (size: 100mm length * 50mm width * 1mm thickness), so that sample fastening side towards deviating from this plate, the length that laterally is parallel to plate of sample, and the edge of sample flushes with the left side, the right and the bottom margin of plate.

Identify the vertical and horizontal of this standard hook material.Cut out sample, described sample has 25mm on being of a size of vertically and 13mm transversely.Use two-sided tape that the suspension hook sample is installed in a copy paper (75gsm; Size: 25mm width * 100mm length) so that sample suspension hook side towards deviating from paper slip, the length that laterally is parallel to paper slip of sample, and the edge of sample flushes with the left side, the right and the top of paper slip.

Metallic plate is placed on (collar sample faces up) on the platform, makes its top (being the end that is not covered by collar sample of plate) deviate from operator's orientation.With the suspension hook sample place (suspension hook is downward) in the collar sample in the heart, make the suspension hook sample laterally be parallel to collar sample laterally, and make paper slip draw end point operation person.Then this sub-assembly is come 5 circulations of rolling (1 circulation is restricted to a forward stroke and a return stroke) with the roller of 5kg.

Spacing of tensile tester is set as 75mm, and the chuck that makes zero.The top of metallic plate placed in upper folder face so that it horizontally in the folder face, allows the end that draws of paper slip dangle downwards.The sample sets of aliging vertically component, and closed upper folder face.Inject in the lower folder face end that draws of paper slip and closure.Force cell makes zero.

Start tensile tester and begin Data Collection.Pull open anchor clamps until suspension hook and collar sub-assembly are threaded off fully with the speed of 300mm/min.Then calculate maximum shear stress (N) by software by capable/extension curve.

Peeling force and repetition peeling force

Peeling force uses equipment mentioned above to measure under extension test.

Identify the horizontal and vertical of mother buckle (collar) material.Cut out specimen, described sample has the 100mm (length) of the 50mm (width) * transversely on being of a size of vertically.

Identify the horizontal and vertical of this standard hook material.Cut out sample, described sample has 25mm on being of a size of vertically and 13mm transversely.Use two-sided tape that the suspension hook sample is installed in a copy paper (75gsm; Size: 25mm width * 100mm length) so that sample suspension hook side towards deviating from paper slip, the length that laterally is parallel to paper slip of sample, and the edge of sample flushes with the left side, the right and the bottom margin of paper slip.

Collar sample is placed on the platform, allows the collar facing up.With the suspension hook sample place (suspension hook is downward) in the collar sample in the heart, make the suspension hook sample laterally be parallel to collar sample laterally, and make the end that draws of paper slip deviate from the operator and point to.Then with 5 circulations of roller rolling (1 circulation is restricted to a forward stroke and a return stroke) with 5kg of this sub-assembly.Modestly drawing of paper slip held towards 180 ° of operator's inflection, make crease next-door neighbour suspension hook sample.Mark collar sample directly over the suspension hook sample is used for repeating to peel off test so that the suspension hook sample can easily be reconnected in same position.

Spacing of tensile tester is set as 75mm, and the chuck that makes zero.The top of collar material placed in upper folder face so that it horizontally in the folder face, allows the end that draws of paper slip dangle downwards.The sample sets of aliging vertically component, and closed upper folder face.Inject in the lower folder face end that draws of paper slip and closure.Force cell makes zero.

Start tensile tester and begin Data Collection.Pull open anchor clamps until suspension hook and collar sub-assembly are threaded off fully with the speed of 300mm/min.Then calculate maximum peeling force (N) by software by capable/extension curve.

In order to repeat to peel off, these two exemplars are removed from tensile tester, the suspension hook sample is re-engaged same position on collar sample, with 5 circulations of its rolling, and again as indicated abovely peel off like that.Can peel off for the third time in a similar manner.Record respectively the each maximum peeling force in peeling off for three times.

Mechanical strength

Fracture Force uses equipment mentioned above to measure under extension test.

Identify the horizontal and vertical of mother buckle (collar) material.Cut out specimen, described sample has the 200mm of 25mm on being of a size of vertically * transversely.

Spacing on the tensile tester is set as 100mm.Chuck and force cell make zero.Sample is injected in the upper folder face, it is aligned in the upper lower clamp vertically, and closed upper folder face.Inject in the lower folder face sample and closure.It is any lax to eliminate that sample should stand enough tension force, but the power that records at force cell is less than 0.05N.

Anchor clamps are pulled open until sample burst with the speed of 100mm/min.Calculate maximum Fracture Force (N) by software by capable/extension curve.

Repeat above-mentioned operation with the sample that cuts out, described sample is of a size of the 200mm on transversely the 25mm * vertically.Record respectively horizontal and vertical Fracture Force.
