Abstract
The utility model belongs to compound substance detection technique field, and a kind of compound substance step bar is provided, and can detect the debonding defect of multiple laying thickness.The technical solution of the utility model comprises: single laying test block, the stepped test block of many layings, glued membrane, artificial defect, place respectively artificial defect in glued membrane both side surface, in the artificial defect of glued membrane one side surface, place single laying test block, in the artificial defect on glued membrane opposite side surface, place the stepped test block of many layings.
Description
Technical field
The invention belongs to compound substance detection technique field, relate to a kind of step bar of Ultrasonic Detection compound substance debonding defect.
Background technology
At present in the actual detection of carrying out composite material parts, run into the part that laying structure is very complicated, laying may present from which floor to tens layers stepped gradual change, and the test block quantity of making is on request many, and every kind of test piece only has a kind of thickness, and form structure is single.When detection, need the corresponding different test blocks of different parts, strengthened testing staff's workload, waste time and energy.
Summary of the invention
The technical problem to be solved in the present invention: a kind of compound substance step bar is provided, can detects the debonding defect of multiple laying thickness.
Technical scheme of the present invention: a kind of compound substance step bar, comprising:
Single laying test block, the stepped test block of many layings, glued membrane, artificial defect,
Place respectively artificial defect in glued membrane both side surface, in the artificial defect of glued membrane one side surface, place single laying test block, in the artificial defect on glued membrane opposite side surface, place the stepped test block of many layings.
Beneficial effect of the present invention: use the step bar of this compound substance, be not only easy to carry certainly but also be convenient to measure use, calibration speed is fast, has the advantages such as reasonable in design, simple in structure, sensing range is wide, effectively improves the quality of products and work efficiency.
Brief description of the drawings
Fig. 1 is a kind of compound substance step bar of the present invention structural representation.
Fig. 2 is a kind of compound substance step bar of the present invention vertical view.
Embodiment
A kind of compound substance step bar, as shown in Figure 1, 2, comprising:
Single laying test block 1, the stepped test block 2 of many layings, glued membrane 3, artificial defect 4, place respectively artificial defect 4 in glued membrane 3 both side surface, in the artificial defect 4 of glued membrane 3 one side surfaces, place single laying test block 1, in the artificial defect 4 on glued membrane 3 opposite side surfaces, place the stepped test block 2 of many layings.
When making, by after single laying test block 1 and the stepped test block 2 difference forming and hardenings of many layings, re-use the glued membrane identical with product, and place artificial debonding defect in glued membrane both sides with simulation unsticking.The size of artificial defect can be carried out by Product Acceptance Review standard.The forming and hardening parameter Ying Yuqi of debonding defect step bar is identical for detection of the parameter of product.Using when this debonding defect step bar, this test block has comprised all layings of product region, in the time of testing product, has understood step bar one-level step when identical with product a part laying, just uses corresponding step to carry out the detection of debonding defect.Probe placement is located in the artificial defect top at a certain step place, carry out instrument regulation, after calibration, start to carry out the unsticking detection in the identical laying of product region, if indicator signal is identical with step test block indicator signal on discovery oscillograph, can be judged to be debonding defect.
Claims (1)
1. a compound substance step bar, is characterized in that, comprising:
