Description
Technical field
The utility model belongs to polymer matrix composites technical field of mold, particularly relates to a kind of mould of preparing felt/upright fibres three-dimensional structure polymer matrix composites.
Background technology
Along with the development of current composite, merely two-dimentional functive is embedded to matrix and can not meet application demand, more and more adopt three-dimensional functive to build composite, thus the performance of reinforced composite.Felt/upright fibres polymer matrix composites, as a kind of composite with 3 d function body, are more and more studied.When in this composite of research, the parameter of felt is on the affecting of some performance, due to the whether smooth test result that can affect these performances of felt, so need to keep the smooth of felt in preparing felt/upright fibres three-dimensional structure polymer matrix composites.On the other hand, the shape of upright fibres in the three-dimensional structure polymer matrix composites of felt/upright fibres, size, uprightly whether, and the spacing of fibre bundle also all can affect the test result of its performance, the spacing of shape, size, erectility and the fibre bundle of the fibre bundle that therefore needs to be kept upright.And in flowing liquid, felt is not easy to keep its smooth state, the upright fibres bundle that the little quality of volume is light is also not easy to keep the parameter of above design, thereby affects the performance that it will be studied, and the impact of performance that test is obtained does not reach the theoretical impact of performance.Therefore in scientific research process, need to optimize the Design of Dies of felt/upright fibres three-dimensional structure polymer matrix composites.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of mould of preparing felt/upright fibres three-dimensional structure polymer matrix composites, can improve and easily bend or concavo-convex situation preparing felt in felt/upright fibres polymer matrix composites process, and the spacing of the shape of the fibre bundle of being kept upright, size, erectility and fibre bundle.
The utility model solves the technical scheme that its technical problem adopts: a kind of mould of preparing felt/upright fibres three-dimensional structure polymer matrix composites is provided, comprise substrate and cover plate, described substrate central interior is provided with rectangular recess, 4 corresponding U-shaped steel are housed on described substrate edges, described U-shaped steel outward opening, bottom surface flush with the edge of groove, on described 4 U-shaped steel, cover plate is housed, the part that described cover plate covers groove top is provided with through hole.
Described substrate is fixedly connected with two sides of U-shaped steel with nut by screw respectively with cover plate.
Described groove length and width are all that 200 millimeters, the degree of depth are 1 millimeter.
Described through hole on the cover board forms square array with 25 × 25 and arranges.
Described through hole radius is 2 millimeters.
The length of described substrate and cover plate and width are all that 240 millimeters, thickness are 10 millimeters.
Described U-shaped steel is divided into two groups, positioned opposite be one group, wherein a group leader is 240mm, another group leader is 200mm, the height of U-shaped steel is 15 millimeters.
Beneficial effect
The utility model compared with prior art, there is following advantage and good effect: while utilizing the utility model mould to prepare felt/upright fibres polymer matrix composites, felt can be fixed, therefore be difficult for bending or concavo-convex situation, upright fibres bundle can keep shape, size, erectility and the fibre bundle spacing of its original design.Utilize the utility model mould to prepare felt/upright fibres three-dimensional structure polymer matrix composites, in the composite obtaining, felt keeps smooth, felt/upright fibres three-dimensional structure polymer matrix composites that its research performance test value is prepared by traditional moulds are more scientific rationally, can predict comparatively accurately the parameter of felt to the relation that affects of its performance.While utilizing the utility model mould to prepare felt/upright fibres three-dimensional structure polymer matrix composites, due to the dark pit of the 1mm digging out make smooth below felt, be difficult for producing bubble; The fibre bundle being inserted by the through hole on cover plate can keep design shape, size, erectility and the fibre bundle spacing of fibre bundle, is of value to the science of experiment.

Detailed description of the invention
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Fig. 1 to 5, a kind of mould of preparing felt/upright fibres three-dimensional structure polymer matrix composites, comprise substrate 1 and cover plate 6, described substrate 1 central interior is provided with rectangular recess 2,4 corresponding U-shaped steel 3 are housed on described substrate 1 edge, described U-shaped steel 3 outward openings, bottom surface flush with the edge of groove 2, on described 4 U-shaped steel 3, cover plate 6 are housed, and the part that described cover plate 6 covers groove 2 tops is provided with through hole 7.
Described substrate 1 is fixedly connected with two sides of U-shaped steel 3 with nut 5 by screw 4 respectively with cover plate 6.
