Description
Technical field
The present invention relates to a kind of method that at least one is used to check the test block of bonding bond quality, test block that this test block especially is made of fibre reinforced materials of preparing.
In the process of the boxcar of making train, be well known that by bonding joint each fibre-reinforced components to be joined together with the boxcar, boxcar.Bonding joint between these boxcar parts should bear static load, bears very big pressure and stress again, for example, and when train can produce very big pressure and stress when turning round.So, must guarantee that bonding joint can bear pressure and the stress that produces in the connecting elements.This can obtain by the quality of checking bonding joint.So require testing result enough accurate, though with guarantee fibre-reinforced components bear at bonding joint also can be firm under the situation of static stress and dynamic stress link together.
Prior art
In order to check the quality of bonding joint, normally in the test experience chamber, some small-sized single fiber reinforcement parts are combined together to form a test block by a bonding joint.Check the quality of this test block cemented side seam that under laboratory condition, prepares by this way then.Although use this test block can obtain some representing characteristic values of the bonding joint between the fibre-reinforced components, but problem is that this test block for preparing under laboratory condition is not at the actual condition of contact that plays a major role in the boxcar used unit in preparation process.Like this, in the process of research laboratory's test block, do not determine not comprise that other influence the factor of bonding bond quality to both having had in the qualitative analysis of bonding joint yet, for example, the actual pretreatment quality of treatment temperature, air humidity, pressure, the pollution level of carrying out the factory of member combination, member, and displacement in cohesive process and stress etc.Therefore, use the precise characteristics value of the bonding joint between the member that the test block of known method preparation is not enough to determine that physical condition forms down.
Summary of the invention
Therefore the purpose of this invention is to provide a kind of method for preparing test block, wherein can obtain test block, and need not manpower, time cost and structure expense from the bonding joint that physical condition forms down.
Can realize purpose of the present invention by the described method of claim 1.
Thus, in order to prepare at least one test block, need two tabular bonded blocks at first at least.In this case, for example in order to make the boxcar of train, this bonded block is two independent members, and these members can be used in sidewall, floor, the car roof area of boxcar.Member for as the boxcar has proved the use fibre reinforced materials, and especially fibre reinforced plastics formation link more has superiority.So just can obtain the lighter firm boxcar structure of weight by advantageous manner.In addition, each bonded block forms at least one projection at it at least on one side.Therefore, the limit of projection and bonded block fuses, thereby this bonded block and projection thereof can be made from a workpiece.For example, can from fibre reinforcement plate downcut corresponding bonded block and above projection.For example, the shape of each bonded block actual with the bonded block use that is installed in the boxcar in the operational size that needs meet substantially.But because projection is designed to the plate-like extending portion branch at bonded block edge, bonded block has the profile that is different from its operational size.The formation of projection means on the bonded block as the test block material and is provided with other materials thus.
Had after these tabular bonded blocks, at least two bonded blocks are combined under physical condition, combination is that the longitudinal edge of a bonded block combines with the longitudinal edge of another bound fraction basically.In this case, " vertically limit " of bonded block just can be understood as a fringe region, and extend continuously along bonded block and the projection that is integrally formed therewith in this zone.Therefore, vertically the limit is to extend along bonded block and the projection that is integrally formed therewith.Then, viscose glue is injected in the zone between the longitudinal edge of the combination of mutually right bonded block and projection thereof, and this has just formed the bonding joint that two bonded blocks are tightly linked together.
After along vertical limit of bonded block it being combined, the projection that its place, vertical limit is combined scales off from bonded block.In downcutting the process of projection, the bonded block that has combined is cut into operational size simultaneously according to its further purposes, these further purposes are for example as the structural member of boxcar.Therefore, can save the process that the bonded block that assembles is further processed according to required size and operating structure.This can simplify production run greatly.The outshot that downcuts comprises the bonding joint of the bonded block of assembling under the physical condition, and it can be used as the quality that test block is checked the bonding joint between the bonded block.
Described test block preparation method operates simply, quick, and economize on the use of funds, because test block can make in the production run of bonded block.Other required operation stepss of preparation test block under laboratory condition have been saved thus.And, not only obtained test block, because bonding joint wherein has the attribute of the actual adhesive joins that forms on bonded block,, be used for checking the actual bonding process that carries out so can be used as archives material.
The preferred implementation of the method for the invention is described referring to other claims.
Preferably the test block that scales off is divided into several independent test block segments.At first, the cutting of test block is proportional with respect to the size of test block segment, the position that these cuttings are more convenient for controlling, proofreading and correct the test block segment in the bonding engaging process of research.Secondly, can obtain a plurality of test blocks, thereby can utilize each test block to test the quality of bonding joint.This makes the bonding joint that can repeated test forms under physical condition, to be sure of test result.
According to a preferred implementation of the inventive method, the size of the bonded block of use is corresponding substantially.This makes these two bonded blocks in this case, to be easy to obtain overlapping vertical limit based on corresponding physical dimension vertically combining with a kind of mirror image symmetrical manner on the limit.
For the formation of bonding joint, be preferably between the bonded block and form at least one adhesive joins by described bonding joint.In this connected, adhesive joins preferably was basically parallel in the zone that vertical limit of bonded block and projection thereof overlaps each other and extends along vertical limit of bonded block.This layout of adhesive joins is guaranteed safety and firm combination between the bonded block.
In order to form test block and each test block segment,, preferably be basically perpendicular to the adhesive joins that runs through projection or test block and cut away projection and/or the independent test block segment of cutting when when the bonded block that combines downcuts.This be basically perpendicular to adhesive joins and vertically the separation method on limit simplified greatly in the subsequent quality test process to cut the processing of test block.
