Abstract
The invention belongs to the technical field of armor protection materials, relates to a human protection material technology, and in particular relates to a composite material for a bulletproof helmet. According to the modified phenolic resin semi-impregnation aramid fiber prepreg, the bonding strength and toughness of the phenolic resin are adjusted through a modifier, and the matrix resin part is impregnated with aramid fiber. The modified phenolic resin semi-impregnation aramid fiber prepreg consists of a modified phenolic resin and an aramid fiber fabric, wherein the matrix resin part is impregnated with aramid fiber; the impregnation rate is between 5 and 20 percent; and the mass percentage of the resin is between 8 and 18 percent. The prepreg has high glue content uniformity and high flexibility and is convenient to use, and a bulletproof aramid composite material product prepared by the prepreg is low in porosity, light in weight, high in structural strength and excellent in bulletproof performance and is applied to the field of human protection and armor protection.
Description
Technical field
The invention belongs to armor facing material technology field, relate to half infiltration prepreg and dependency structure composite, relate to the physical protection material technology, particularly the bulletproof halmet composite.
Background technology
In the physical protection field, particularly bulletproof halmet not only has requirement to bulletproof performance, and the applicability under weight, structural strength and the high and low temperature environment is also had very high requirement, therefore, need to use the high performance composites that has safeguard function and structural strength concurrently.
Aramid fiber has the characteristics such as high strength, high-modulus, thus the high-performance fiber ballistic composite to adopt aramid fiber be to strengthen body more.Phenolic resins has good mechanical property, heat resistance and electrical insulating property, and shaping speed is fast, and cost is low, is desirable thermoset substrate resin.But also there is the defective of poor toughness, easy embrittlement in phenolic resins, can not give full play to high strength and the high-modulus characteristic of aramid fiber, thereby the composite bulletproof performance is reduced.Therefore phenolic resins is carried out toughening modifying extremely important, by adjusting the toughness of phenolic resins, adjust the interface cohesive force between resin and the aramid fiber, improve the ballistic performance of aramid fiber composite material.A lot of to phenolic resin modified research, but particularly the helmet is with the study on the modification of ballistic composite seldom for ballistic composite.
Partly infiltrate prepreg as a kind of special prepreg, with the main difference of common prepreg be that cure stage forward part fiber keeps that do and untreated state.At present for the research of semi-prepreg with use seldom, CN 101492573A relates to the prepreg that partly infiltrates of aathermoset resin system, the impregnation rate of matrix resin surpasses 20%, because the resin-dipping rate is high, can not satisfy the demand with the aramid fiber composite material bulletproof performance of the method preparation.
