Abstract

The invention discloses a manufacturing process for a safety shoe toecap and the manufactured safety shoe toecap. The manufacturing process comprises the steps that carbon fiber prepreg and glass fiber prepreg are cut into required shapes through an automatic cutting machine, the cut carbon fiber prepreg and the cut glass fiber prepreg are laid on the surface of a core mold to form a preformed body, the preformed body containing the core mold is placed in an outer toecap mold and integrally packaged through a vacuum bag, and the safety shoe toecap is obtained through curing molding by means of a drying oven. According to the manufacturing process for the safety shoe toecap and the manufactured safety shoe toecap, the prepreg composed of the carbon fiber prepreg and the glass fiber prepreg are selected and used, carbon fiber cloth provides main strength, rigidity and smooth appearance, glass fiber cloth can provide enough impact performance, and compared with traditional steel toecaps and plastic toecaps, the safety shoe toecap has the characteristics of being low in weight, high in strength, good in corrosion resistance, high in impact performance and good in fire resistance.

Description

technical field [0001] The invention relates to the field of preparation of toe caps for safety shoes, in particular to a manufacturing process of toe caps for safety shoes and the produced toe caps for safety shoes. Background technique [0002] Safety shoes are footwear that protect feet and legs from foreseeable injuries and are worn in different workplaces. They are high-tech and high-value-added footwear products and are widely used in machinery, metallurgy, construction, chemical, Pharmaceutical, mining, oil field, electric power and other industries. In the toe protection safety shoes, there are five protective performance levels: An1, An2, An3, An4 and An5, with An1 being the highest and An5 being the lowest. The high-level toe protection safety shoes have high technical indicators of pressure resistance and impact resistance at the front end, and the protection of the toes is good. The more easily the toes are smashed or crushed, the more serious the injury is. Ch...
