Technical field
The present invention relates to the method for a kind of polyparaphenylene's benzo-dioxazole (hereinafter to be referred as PBO) fiber surface modification.
Background technology
In recent years, conflict and war all over the world is continuous, and war industry obtains fast development, and various countries more and more come into one's own to the research and development of high performance material.Composite is an important branch in material field, is bringing into play the effect that becomes more and more important in war industry, has occupied critical role.Along with the continuous development of high-tech level, also more and more higher to the requirement of composite property, not only require higher specific strength, specific modulus, but also to have more excellent weatherability, heat endurance, anti-ablation, anti-erosion, damping, suction ripple, saturating ripple, etc.Fiber is the basic composition of composite, and the quality of its performance has determined performance of composites to a great extent.Pbo fiber because of its outstanding physicochemical property by various countries researcher extensive concern, reach 5.8GPa as its intensity, modulus is up to 280GPa, limited oxygen index (LOI) is 68, maximum operation (service) temperature and decomposition temperature are respectively 350 ℃ and 650 ℃, these characteristics are much better than existing organic fiber, and are enough to make it and high-performance carbon fibre to compare favourably, so be described as the super fiber of 21 century.
Yet, because of pbo fiber surface-activity and self structure characteristics, the cementability of fiber and resin matrix is very poor, often have low layer with pbo fiber reinforced composite materials goods and cut intensity, compressive strength, and cut performance and compression performance by the layer that the method for introducing hydrogen bond can not improve the pbo fiber reinforced composite because of resin content is low.Therefore, by pbo fiber is carried out surface treatment,, may be layer effective way of cutting performance and compression performance that improves the pbo fiber reinforced composite to improve the cementability of pbo fiber and resin matrix.
The surface modifying method of fiber is more, flame method, chemical pretreatment solution oxidizing process, Low Temperature Plasma Treating,, surperficial high-energy radiation grafting method, surface heat gaseous cyaniding and top layer cladding process or the like, also have the compound use of several method.These methods are all at the surface property that has improved fiber in varying degrees, but are cost with the mechanical property or the hot property of loss fiber mostly.Therefore, the new surface modifying method of research and development has great importance.
Summary of the invention
In order to overcome the problem that background technology exists, the object of the present invention is to provide a kind of method of polyparaphenylene's benzo-dioxazole fiber surface modification.
The technical solution adopted for the present invention to solve the technical problems is that the step of this method is as follows:
