Abstract
The utility model relates to a toe cap, in particular to a safety toe cap made of new type composite material. The toe cap is composed of an upper surface, lateral surfaces and a bottom edge. The thickness of every part of the toe cap is different. The toe cap is produced integrally, and the toe cap is composed of a plurality of composite material layers. Every layer is made of continuous fibre fabric previously dipped in thermosetting resin, and every fibre layer is arranged in specific direction. Fibre adopts continuous fibre fabric, and the thermosetting resin adopts epoxy resin, ethylene resin, unsaturated polyester resin, etc. The adoption of the continuous fibre fabric mainly overcomes the shortage of staple fibre on mechanical property. A toe cap with high quality, light weight, strong press resisting and impact resisting performances and controllable mechanical property is provided.
Description
Technical field
The utility model relates to a kind of toe-cap, especially a kind of safety toes of advanced composite material (ACM).
Background technology
Current social labour protection has become the problem that each labourer is concerned about conscientiously, and thus, the labor protection facilities of each side are also corresponding a lot, and a kind of to be used to protect the safety toes of labourer's personal safety be exactly one of them.The safety toes security that metal is made is very high has also used a lot of years, but weight is heavier, makes wearer's action painstaking easily; In recent years terrorism is in vogue in addition, the airport, various countries, port and various momentous conference turnover sluice gate, all improve safety check and do not have metal detector, the steel toe-cap can cause alarm, causing much inconvenience of user, just arises at the historic moment to nonmetal safety shoe (Non-metallic shoes) demand in various countries, and fiber reinforced plastic also begins to be applied to make safety toes.In general, fiber reinforced plastic (abbreviation composite) can be divided into thermoplasticity and thermosetting two classes, and thermoplastic composite is poorer than the thermosetting composite on impact strength and the withstand voltage intensity that contracts, as described in No. the 352516th, Taiwan patent announcement, be composite material moulded the forming that mixes by indefinite direction chopped strand of multilayer and thermoplastic resin, because fiber is short, direction is indefinite, make intensity lower and unstable, can't make light mass and thin wall, the safety toes that the intensity height is stable again.
Summary of the invention
It is lighter that the utility model mainly provides a kind of weight, resistance to compression and strong shock resistance, the high-quality toe-cap that engineering properties is controlled, solve the heavier and use inconvenience of weight of the safety toes of existing in prior technology employing metal material making, reach general thermoplastic composite undercapacity and instability, can't make the technical problem of light mass and thin wall high strength safety toes.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: toe-cap is to be made of upper surface, side and base, toe-cap each several part thickness is variant, toe-cap is made into one, toe-cap is made of multilayer materials, the long fine woven cloth of continuity that each layer employing crossed through the thermosetting resin pre-preg is made, and each fibrage is arranged with specific direction.Fiber adopts long fine (continuous fiber) woven cloth, and thermosetting resin then can adopt and be not limited to epoxy resin, vinylite, unsaturated polyester resin etc.Adopt long fine woven cloth, mainly overcome the deficiency on the mechanical performance of short fiber.
As preferably, described ground floor is vertical with the machine direction of the second layer, and all the other each layers are identical with ground floor.
As preferably, described fibrage can adopt the long fine woven cloth of continuity, and material can be glass fibre, charcoal fiber, unsaturated polyester fiber and aromatic series polyamide fiber.Long fine woven cloth is arranged according to the number of plies that designs and machine direction lamination, wherein adopts the long fibre of continuity that the impact strength and the compression strength of composite safety toes maximum are provided, and machine direction and the arrangement fixed, then guarantees the high stability of its intensity.
As preferably, the width on described base is 8-12mm.
Therefore, it is lighter to the utlity model has weight, resistance to compression and strong shock resistance, the high-quality toe-cap that engineering properties is controlled.
Description of drawings:
Accompanying drawing 1 is the structural representation of the safety toes of advanced composite material (ACM).
Accompanying drawing 2 is cutaway views of the safety toes of advanced composite material (ACM).
The concrete example of implementing:
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: shown in attached Fig. 1 and 2, the safety toes of advanced composite material (ACM) is by the upper surface 1 that constitutes the vamp basis, and side 2 and base 3 constitute, and the toe-cap upper surface has certain gradient, and the width on base is 10mm.The material of toe-cap is to adopt the multilayer materials structure, form a kind of similar sandwich structure, each layer adopts specific fiber alignment direction, fibrous material can adopt glass fibre, charcoal fiber, the isometric fibre of aromatic series polyamide fiber, help providing the mechanical performance of toe-cap like this, alleviate the weight of toe-cap.After ground floor 4 selected directions, the fibrage direction of the second layer 5 and the machine direction of ground floor 4 are miter angle, and the 3rd layer direction is identical with the machine direction of ground floor 4.Choosing of different fiber specific directions, form a kind of multiaxis to and be the safety toes base material of many space structures, help improving the resistance to compression and the impact resistance of toe-cap like this.After cutting good material, it is piled up according to the design lamination, specifically be that the preimpregnation blank is cut into small pieces, then the moulding material after the pre-shape of lamination (pre-formed) is put into the moulding of mould HTHP, the direction that these small pieces are placed at different layers has nothing in common with each other, and the size of different layers fiber and orientation and formwork shape and required performance are complementary.The preimpregnation blank is that the resin with constant concentration is evenly distributed on the sheet stock of making appropriate viscosity in the long fine woven cloth.Sheet stock is by the continuous tow direction stacked in multi-layers of stipulating in advance in the technical process.Because fiber does not relatively move between every layer viscous layer.Interlayer has only resin to flow.Therefore can be fixed thickness and the controlled high-quality toe-cap of engineering properties.It is vinyl esters, unsaturated polyester (UP), epoxy or the polyurethane of 25-50% that resin system can adopt the resin quality percentage composition.
