[0020] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0021] Adhesive bonding is one of the main methods for joining composite materials, offering advantages such as high bonding efficiency, weight reduction, fatigue resistance, and the absence of stress concentration caused by drilling. To evaluate bond strength, adhesive performance, and substrate-adhesive compatibility, various bonded specimens need to be prepared for mechanical testing. Preparing bonded specimens requires heating to cure the adhesive, necessitating the use of molds to fix the unformed specimens. Currently, most molds for forming specimens are custom-made according to the specimen's shape, meaning each mold can only produce specimens of one size, resulting in poor flexibility.

[0022] Based on this, the present invention provides an adhesive sample forming apparatus and method. When using this adhesive sample forming apparatus, firstly, depending on the type of sample to be prepared, the position of the first forming member in the second direction is adjusted to set the width of the receiving groove. Then, the position of the second forming member in the first direction is adjusted to set the length of the receiving groove. Next, the adhesive material is placed into the receiving groove to form the adhesive material. After the adhesive material has cured, the formed sample can be removed. This solution, by combining different positions of the first forming member and different positions of the second forming member, can prepare different types of samples, offering high flexibility.

[0023] Please see Figure 1 An exemplary embodiment of the present invention provides an adhesive sample forming apparatus, including a base 100, a plurality of first forming elements 200 and a plurality of second forming elements 400. The base 100 includes a support surface 110 for supporting the sample. The support surface 110 is set as the upper surface of the base 100. The support surface 110 may be set as a horizontal surface, for example. In an alternative embodiment, the support surface 110 may also be set at an angle relative to the horizontal surface.

[0024] At least a portion of the first molded component 200 is disposed above the support surface 110, and the portion of the first molded component 200 above the support surface 110 is arranged along a first direction in its length direction. A plurality of first molded components 200 are spaced apart along a second direction, with the first direction and the second direction forming an angle. For example, the angle between the first direction and the second direction can be set to 90°. The first direction is set as... Figure 1 The x-axis direction is set, and the second direction is set to Figure 1 The y-axis direction in the middle. Two adjacent first molding parts 200 divide the space above the support surface 110 into a receiving groove 300 for accommodating the sample. That is, the extending direction of the receiving groove 300 is also set along the first direction. The first molding part 200 can be adjusted in position along the second direction to change the width of the receiving groove 300.

[0025] The second molding component 400 is detachably mounted on the base 100, and a second molding component 400 is provided at both ends of each receiving groove 300. The position of the second molding component 400 can be adjusted along the first direction to adjust the length of the receiving groove 300. Different types of specimens can be prepared by different combinations of the positions of the first molding component 200 and the second molding component 400. The different types of specimens are specifically limited to type I specimen 700, single-joint specimen 800, and T-type specimen 900.

[0026] For example, the second molded part 400 may be fixed to the base 100 by screws. In an alternative embodiment, the second molded part 400 and the base 100 may also be fixed by bolts.

[0027] For example, a second molding member 400 is provided at each end of each receiving groove 300. In an alternative embodiment, when the width of the sample is large, multiple second molding members 400 may be provided at each end of each receiving groove 300. The multiple second molding members 400 are arranged at intervals along the second direction, thereby restricting the position of the sample from multiple points and improving the stability of the sample positioning.

[0028] In the adhesive sample forming apparatus provided in this embodiment, when using this apparatus, firstly, depending on the type of sample to be prepared, the position of the first forming member 200 in the second direction is adjusted to set the width of the receiving groove 300. Then, the position of the second forming member 400 in the first direction is adjusted to set the length of the receiving groove 300. Next, the adhesive material is placed into the receiving groove 300 to form the adhesive material. After the adhesive material has cured, the formed sample can be removed. This solution, through different combinations of the positions of the first forming member 200 and the second forming member 400, can prepare different types of samples, offering high flexibility.

[0029] In one exemplary embodiment, please refer to Figure 1 The base 100 also includes a pair of first side surfaces 120, which are respectively disposed at both ends of the base 100 along a first direction. A first adjustment groove 121 is provided on the first side surface 120, which is arranged along a second direction in the length direction. At least a portion of the first molded part 200 is slidably assembled in the first adjustment groove 121, which is used to limit the sliding direction of the first molded part 200.

[0030] The first adjustment groove 121 may also be marked with a scale, which facilitates the positioning of the first molded part 200 and the control of the width of the receiving groove 300.

[0031] For example, the first adjustment groove 121 is configured with a trapezoidal cross-section perpendicular to its length direction, thereby preventing the first molded part 200 from dislodging from the first adjustment groove 121 and restricting the first molded part 200 to slide only along the length direction of the first adjustment groove 121. In an alternative embodiment, the shape of the first adjustment groove 121 is not limited, as long as it can restrict the first molded part 200 to slide along the second direction.

[0032] In this embodiment, the position of the first molded part 200 in the second direction can be adjusted by sliding it in the first adjustment groove 121, thereby adjusting the width of the receiving groove 300 according to the size of the sample and improving the flexibility of use. At the same time, the first adjustment groove 121 can improve the stability of the first molded part 200 when it is adjusted along the second direction.

[0033] In one exemplary embodiment, please refer to Figure 1The first molded part 200 includes a molding part 210 and an adjustment part 220. The length direction of the molding part 210 is arranged along the first direction. The molding part 210 is disposed above the support surface 110, and the bottom surface of the molding part 210 is in contact with the support surface 110.

[0034] Two adjustment parts 220 are provided, one at each end of the forming part 210. At least a portion of the adjustment part 220 is slidably fitted into the first adjustment groove 121, and the portion of the adjustment part 220 slidably fitted into the first adjustment groove 121 is adapted to the shape of the first adjustment groove 121. A first locking member 230 is provided on the adjustment part 220, which is used to lock and fix the adjustment part 220 to the base 100.

[0035] For example, the first locking member 230 can be configured as a first threaded rod, which is threadedly connected to the adjusting part 220. When the first threaded rod is tightened, one end of the first threaded rod applies a clamping force to the base 100. By simultaneously tightening the first locking members 230 provided on the two adjusting parts 220, the first molded part 200 is locked and fixed on the base 100. A first knob is installed at the end of the first threaded rod away from the base 100 to facilitate rotation of the first threaded rod.

[0036] In this embodiment, the molding part 210 is used to divide the space above the support surface 110 to form a receiving groove 300. By using two adjustment parts 220 to slide within the first adjustment groove 121 to restrict the adjustment direction of the molding part 210, the position of the molding part 210 along the second direction can be stably adjusted, thereby making it suitable for forming samples of different widths and improving the flexibility of use.

[0037] In one exemplary embodiment, please refer to Figure 1 The second molded part 400 includes an adjusting screw 410 and a screw seat 420. At least a portion of the screw seat 420 is slidably fitted into the first adjusting groove 121. A second locking member 430 is provided on the screw seat 420 to lock and fix the screw seat 420 to the base 100. The adjusting screw 410 is threadedly fitted into the screw seat 420. The axis of the adjusting screw 410 is set along a first direction. By rotating the adjusting screw 410, the position of the adjusting screw 410 along the first direction is changed, thereby adjusting the length of the receiving groove 300.

[0038] For example, the second locking member 430 may be configured as a second threaded rod, which is threadedly connected to the screw seat 420. When the second threaded rod is tightened, one end of the second threaded rod applies a clamping force to the base 100, thereby locking the screw seat 420 onto the base 100. A second knob is installed at the end of the second threaded rod away from the base 100 to facilitate rotation of the first threaded rod.

[0039] For example, a third knob is installed at the end of the adjusting screw 410 away from the receiving groove 300, so as to facilitate rotating the adjusting screw 410 to complete the adjustment of the adjusting screw 410.

[0040] In this embodiment, the screw seat 420 is slid along the first adjustment groove 121, and the position of the screw seat 420 is adjusted so that the adjusting screw 410 corresponds to the receiving groove 300. Then, the second locking member 430 is tightened to fix the screw seat 420 to the base 100. Then, the adjusting screw is rotated to adjust the position of the adjusting screw in the first direction, thereby adjusting the length of the receiving groove 300, so as to be suitable for samples of different lengths and improve the flexibility of use.

[0041] In one exemplary embodiment, please refer to Figure 1 The adhesive bonding sample forming device also includes a cover 500 and a vertical adjustment member 600. The cover 500 covers the support surface 110. The vertical adjustment member 600 is located between the cover 500 and the base 100, and is used to adjust the distance between the cover 500 and the support surface 110. The vertical adjustment member 600 includes a contact surface 610 for contacting the cover 500. The contact surface 610 is the upper surface of the vertical adjustment member 600. A positioning part 611 protrudes from the contact surface 610. The cover 500 is provided with a positioning groove 612 that matches the positioning part 611. The positioning part 611 and the positioning groove 612 cooperate to complete the positioning of the cover 500 and the base 100.

[0042] For example, the positioning part 611 can be configured as a triangle, so that during the installation of the cover 500, the inclined surface of the positioning part 611 can be used as a guide surface to enable the cover 500 and the vertical adjustment member 600 to be stably assembled. In an alternative embodiment, the shape of the positioning part 611 is not limited, as long as it can enable the positioning part 611 and the positioning groove 612 to be assembled in the vertical direction.

[0043] The cover 500 is placed on the support surface 110, which means that the cover 500 is placed above the support surface 110, which can limit the height of the receiving groove 300, but does not limit the cover 500 from fitting against the support surface 110.

[0044] In this embodiment, the vertical adjustment component 600 adjusts the distance between the cover 500 and the support surface 110, thereby limiting the height of the receiving groove 300 so that the height of the receiving groove 300 is equal to the height of the sample. Thus, the cover 500 presses down on the sample and stably confines the sample in the receiving groove 300, further preventing the sample from being misaligned or deformed during the fixing process and ensuring the quality of the finished product.

[0045] In one exemplary embodiment, please refer to Figure 1The base 100 also includes a pair of second side surfaces 130, which are disposed opposite to each other at both ends of the base 100 along the second direction. The second side surfaces 130 are provided with second adjustment grooves 131 arranged vertically along the length direction. At least a portion of the vertical adjustment member 600 is slidably assembled in the second adjustment grooves 131. The vertical adjustment member 600 is provided with a third locking member 620, which is used to lock and fix the vertical adjustment member 600 to the base 100.

[0046] For example, the third locking member 620 may be configured as a third screw, which is threadedly connected to the vertical adjustment member 600. By tightening the third screw, the third screw applies a clamping force to the base 100, thereby locking and fixing the vertical adjustment member 600 and the base 100, thereby fixing the distance between the cover 500 and the support surface 110, and preventing the sample to be prepared placed in the receiving groove 300 from being misaligned or deformed.

[0047] For example, a scale may also be provided on the second adjustment groove 131 to facilitate control of the position of the vertical adjustment member 600.

[0048] In this embodiment, by sliding the vertical adjustment member 600 on the second adjustment groove 131, the position of the vertical adjustment member 600 is changed, thereby adjusting the distance between the cover 500 and the support surface 110, so that the height of the receiving groove 300 is the same as the height of the sample to be prepared. Then, the vertical adjustment member 600 is locked and fixed to the base 100 by the third locking member 620. At this time, the length, width and height of the receiving groove 300 are all adapted to the sample to be prepared, thereby stabilizing and limiting the sample before it is fixed.

[0049] Please see Figure 5 Another exemplary embodiment of the present invention provides a method for forming adhesive samples, applied to the above-described adhesive sample forming apparatus, the method comprising: S100. Adjust the spacing between two adjacent first molding parts along the second direction to match the width of the sample to be prepared. The two adjacent first molding parts divide the space above the support surface into a receiving groove for accommodating the sample to be prepared. Adjust the position of the second molding part in the first direction to adjust the length of the receiving groove to match the length of the sample to be prepared.

[0050] The adjustment of the spacing between two adjacent first molding parts 200 along the second direction is specifically achieved through the following steps: the first locking member 230 is rotated to stop applying pressure to the base 100. At this time, the adjustment part 220 of the first molding part 200 can slide along the extension direction of the first adjustment groove 121, i.e., the second direction, thereby adjusting the position of the first molding part 200 along the second direction. The spacing between two adjacent first molding parts 200 can be determined by the scale marked on the first adjustment groove 121. The spacing between the two adjacent first molding parts 200 is adjusted to be equal to the spacing of the sample to be prepared. Then, the first locking member 230 is rotated and fixed again.

[0051] The adjustment of the position of the second molding part 400 in the first direction, thereby adjusting the length of the receiving groove 300 to match the length of the sample to be prepared, is specifically achieved through the following steps: First, the second locking member 430 is rotated to stop applying pressure to the base 100. At this time, the screw seat 420 can slide along the first adjustment groove 121, that is, slide along the second direction. By adjusting the position of the adjusting screw 410 in the second direction through the sliding of the screw seat 420 in the second direction, the adjusting screw 410 is positioned within the width range of the receiving groove 300. The second locking member 430 is then tightened again to fix the screw seat 420. Then, the adjusting screw 410 is rotated to adjust its position in the first direction, thereby adjusting the length of the receiving groove 300 until the length of the receiving groove 300 matches the length of the sample to be prepared.

[0052] It should be noted that in this embodiment, the length of the sample to be prepared refers to the length of the portion of the sample contained in the receiving groove 300.

[0053] S200. Place the sample to be prepared in the receiving tank.

[0054] For example, when the sample to be prepared is a Type I sample 700, please refer to... Figure 1 and Figure 3The Type I specimen 700 includes a first ply 710 and a second ply 720 stacked together. An adhesive portion 140 is provided between the first ply 710 and the second ply 720 for bonding and fixing them together. The adhesive portion 140 may be made of adhesive. An isolation layer 730 is provided between the first ply 710 and the second ply 720. The isolation layer 730 is located on one side of the first ply 710 and the second ply 720 and only covers a portion of the contact surface 610 of the first ply 710 and the second ply 720. The isolation layer 730 prevents the covered portion of the first ply 710 and the second ply 720 from bonding, thus forming a pre-existing crack. The sample to be prepared is placed in the receiving tank 300 and is achieved through the following steps: the uncured first ply 710 and the second ply 720 are placed in the receiving tank 300, and the second ply 720 is lifted off from one side. Then, the isolation layer 730 is placed on one side of the upper surface of the first ply 710, and the second ply 720 is laid back.

[0055] For example, when the sample to be prepared is a T-type sample 900, please refer to... Figure 1 and Figure 4 The T-type specimen 900 includes a third ply 910 and a fourth ply 920. An adhesive portion 140 is provided between the third ply 910 and the fourth ply 920. Along the length of the third ply 910 and the fourth ply 920, the adhesive portion 140 is only provided on a portion of the contact surface 610 of the third ply 910 and the fourth ply 920, that is, one side of the third ply 910 and the fourth ply 920 does not have an adhesive portion 140. At this time, the specimen to be prepared is placed in the receiving groove 300, which is achieved by the following steps: the third ply 910 and the fourth ply 920 coated with the adhesive portion 140 are sequentially laid in the receiving groove 300.

[0056] For example, when the sample to be prepared is a single-joint sample 800, please refer to... Figure 1 and Figure 2 The single-joint sample 800 includes a first overlapping portion 810 and a second overlapping portion 820. The length direction of both the first overlapping portion 810 and the second overlapping portion 820 is arranged along a first direction. The first overlapping portion 810 and the second overlapping portion 820 are partially bonded and fixed. The first overlapping portion 810 is provided with a first stabilizing portion 830.

[0062] In this embodiment, when using this adhesive sample forming apparatus, firstly, the position of the first forming member 200 in the second direction is adjusted according to the type of sample to be prepared, so as to set the width of the receiving groove 300. Then, the position of the second forming member 400 in the first direction is adjusted to set the length of the receiving groove 300. Next, the adhesive material is placed into the receiving groove 300 to form the adhesive material. After the adhesive material has cured, the formed sample can be removed. This solution can prepare three types of samples—I-type sample 700, single-joint sample 800, and T-type sample 900—by combining different positions of the first forming member 200 and different positions of the second forming member 400, offering high flexibility.

[0063] In an exemplary embodiment, when the specimen to be prepared is a Type I specimen 700, the spacing between two adjacent first molding members 200 along the second direction is adjusted to match the width of the specimen to be prepared. The two adjacent first molding members 200 divide the space above the support surface 110 into a receiving groove 300 for accommodating the specimen to be prepared. The position of the second molding member 400 in the first direction is adjusted, thereby adjusting the length of the receiving groove 300 to match the length of the specimen to be prepared. This includes: Adjust the spacing between adjacent first molded parts to match the width of the I-type specimen; The position of the second molding parts located at both ends of the receiving groove is adjusted in the first direction, thereby adjusting the length of the receiving groove to match the length of the I-type sample. Multiple second molding parts are spaced apart along the second direction to achieve multi-point limiting of the I-type sample 0.

[0064] In an alternative embodiment, when the specimen to be prepared is a single-joint specimen 800, the spacing between two adjacent first molding members 200 along the second direction is adjusted to match the width of the specimen to be prepared. The two adjacent first molding members 200 divide the space above the support surface 110 into a receiving groove 300 for accommodating the specimen to be prepared. The position of the second molding member 400 in the first direction is adjusted, thereby adjusting the length of the receiving groove 300 to match the length of the specimen to be prepared. This includes: The spacing between adjacent first molded parts is adjusted to match the width of the single-joint sample. That is, the width of the receiving groove 300 is the same as the width of the first overlap 810 and the second overlap 820.

[0065] The position of the second molding part located at both ends of the receiving groove is adjusted in the first direction, thereby adjusting the length of the receiving groove to match the length of the single-connection sample.

[0066] The length of the single-joint sample 800 refers to the distance from the end of the first overlap 810 away from the second overlap 820 to the end of the second overlap 820 away from the first overlap 810.

[0067] In an alternative embodiment, when the specimen to be prepared is a T-shaped specimen 900, the spacing between two adjacent first molding members 200 along the second direction is adjusted to match the width of the specimen to be prepared. The two adjacent first molding members 200 divide the space above the support surface 110 into a receiving groove 300 for accommodating the specimen to be prepared. The position of the second molding member 400 in the first direction is adjusted, thereby adjusting the length of the receiving groove 300 to match the length of the specimen to be prepared. This includes: Adjust the spacing between adjacent first molded parts to match the width of the T-shaped sample.

[0068] Adjust the position of the second molded parts located at both ends of the receiving groove in the first direction to adjust the length of the receiving groove and match the length of the T-shaped sample.

[0069] In this embodiment, the positions of the first molded part 200 and the second molded part 400 can be adjusted specifically according to the type I specimen 700, the single-joint specimen 800 and the type T specimen 900.

[0070] This invention can prepare three types of specimens, namely I-type specimens 700, single-joint specimens 800, and T-type specimens 900, by combining different positions of the first molding part 200 with different positions of the second molding part 400, which provides high flexibility in use.
