Description
Technical field
The present invention relates to the enhanced compound pre- orientation fabric of one kind, belong to fabric arts.
Background technology
With material science and technology continue to develop, for manufacture compound pre- directional material fibre reinforcement kind increasingly
It is many, the factors such as processing performance, performance, price and environmental protection are considered when selecting.The shape of compound pre- orientation Material reinforcement
Formula can be reinforcing fiber in itself or enhanced fabrics and cloth, fibrofelt, the fiber braid of two and three dimensions or
Stitch.
The pre- directional material of advanced composite of Aero-Space high-end applications must make reinforcement, high-performance using high-performance fiber
Fiber define Main Basiss be its excellent mechanical property, i.e. lightweight, high-strength and Gao Mo, that is, unit mass intensity and
Modulus, referred to as specific strength and specific modulus, the current main product of high-performance fiber is carbon fiber, in addition to aramid fiber and supra polymer
Polyethylene fibre, their mechanical property is than traditional structural material, the aluminium alloy of such as high-strength light, it is taller go out manyfold,
It is very suitable for the compound pre- orientation material components of manufacture Aero-Space, wind-powered electricity generation structure.
As shown in table 1, the mechanical property of different fibers has very big difference, and the advantage of glass fibre is good insulating, resistance to
It is hot, anticorrosive, high mechanical strength, but having the disadvantage property is crisp, and wearability is poor.Common glass fibre is combined pre- directional material, close
Degree will be higher by carbon fiber and be combined pre- directional material more than 1/3, and to be only carbon fiber be combined the 2/3 of pre- directional material to tensile strength,
Modulus is then lower, less than 1/3.Therefore study the reinforcing fiber of high-strength, Gao Mo and low-density and become fiber composite and orient material in advance
Expect a direction of development.And aramid fiber has the Optimality such as superhigh intensity, high-modulus and high temperature resistant, acidproof, alkaline-resisting, lightweight
Energy.Ultra high molecular polyethylene fiber impact resistance is good, and specific energy absorption is big, and protection dress material, helmet etc. can be made.In wind-powered electricity generation
The application aspects such as blade, automobile, more and more higher is required to the strength of materials, and glass fabric product is difficult in some component capabilities
Meet its requirement.Existing single high performance reinforcing fiber is difficult to meet design requirement in terms of partial properties, and considers into
This factor, it is therefore desirable to introduce the more preferably fiber fractionation incorporation of other types intensity and modulus in fabric construction to strengthen fabric
Performance.Carbon fiber and its be combined pre- directional material due to density is small, intensity is high, high-low temperature resistant the features such as.Carbon fiber is certainly
Since appearance, maturation and the decline of cost with technology, application field are used by Aero-Space, national defence and Leisure Sport
Product, expand to the emerging application fields such as reinforced plastics, pressure vessel, building reinforcing, wind-power electricity generation, drilling platforms.
The mechanical property of the different fibers of table 1
