Description
Technical field
The present invention relates to a kind of Bulletproof helmet body and preparation method thereof.
Background technology
From the antagonism of war, bulletproof equipment is the inevitable outcome of interpromoting relation in five elements of accompanying with bullet class weapon.At present, conventional weapon development rapidly, progressively improves the threat level of individual soldier, for improving shellproof survival ability and the battlefield locomotivity of individual soldier, must develop the ballistic composite system of efficient and light weight.
The shortcoming of metal bulletproof halmet is that the quality of helmet body is comparatively large, wears dumb, has had a strong impact on the performance of soldier's tactical operation.And adopt high-performance fiber, as aramid fiber or superhigh molecular weight polyethylene fibers, by bulletproof halmet prepared by machine knits acquisition fabric, it is larger that the mechanical property of fiber is subject to the impact that arrow shaft shuttles back and forth in weaving process, the intensity of fiber is some losses, thus affects the ballistic performance of helmet manufactured goods.
Multi-shaft warp knitting technology is a kind of Novel multi-bit inlaid thread knitting skill grown up in respective tricot machine type respectively by German LIBA company and KARL MAYER company in recent years.By the multi-axial tricot prepared by this technology, be all lined with enhancing yarn at 0 °, 90 ° and ± θ (30 °≤θ≤90 °), multilayer yarn sheet is strapped in together by warp plain stitch or pillar stitch.Therefore, multi-axial tricot is a kind of multiply cloth.Fleece-laying different directions (lining yarn system) and through-thickness (bondage system) in face form the three-dimensional network overall structure be made up of fibre bundle.Utilize this technology, stretched straight parallel, vertical or be introduced in fabric construction with required angle without curling yarn (i.e. fibre bundle), realize the pre-designed orientation of the most effective structure and strengthen.In structural stability, mechanical characteristic, economy, multi-axial tricot all has the unrivaled advantage of common machine fabric.
The distinguishing feature that multi-shaft warp knitting enhancing fabric is used for industrial field of compound material is: structural design is flexible, isotropic resistance to stress and strain property, higher tear-proof transitivity and good conformal performance.It mainly overcomes traditional ply angles interlayer without contact, and shear strength is poor, the defect of easy layering; It also avoid woven fabric yarn flexing, strength efficiency is low simultaneously, the shortcoming that fibre damage is large, and the mechanical property of enhancing yarn is fully used.In addition, it is high that multi-shaft warp knitting technology also has production efficiency, and technical matters is simple, mechanization degree advantages of higher.
