An innovative application of high performance fiber, honeycomb structure? Bulletproof composite material?

In the field of composite materials , para-aramid fibers (P-ARF) are mainly used in the form of fabrics and slings, and meta-aramid fibers (m-ARF) are used in honeycomb structures and the like.

1 fabric

Italy G.ANGELONI company specializes in the production of high modulus P-ARF, high strength carbon fiber (HS-CF), high modulus carbon fiber (HM-CF), polyarylate "Vectran" fiber (LCPF), GF and hybrid fabric and unidirectional tape Manufacturer.

There are 62 varieties of P-ARF fabrics and hybrid fabrics, 100 kinds of PAN-CF and hybrid fabrics, 11 kinds of LCPF and hybrid fabrics, and 3 kinds of MP-CF. These fabrics and unidirectional belts can be processed into A variety of beautiful composite products. These fibers can also be interwoven into various innovative fabrics with titanium, stainless steel, copper, pure gold, silver, and the like.

American A&P Technology produces a variety of P-ARF, CF, GF and hybrid fiber woven sleeves, unidirectional fabrics, nonwovens , woven fabrics, woven flat ribbons, preforms, etc., of which P-ARF sleeve braid There are 21 kinds of specifications, 15 kinds of ARF and CF hybrid braided sleeves, 19 kinds of CF braided sleeves, and 22 kinds of CF and other fiber braided sleeves. The product can be used in composite parts such as airplanes, bicycles, yachts, wind turbine blades and the like.

The United States Saint-Gobain ADFORS produces a variety of angle-reinforced plain weave fabrics, including ARF, CF, GF, UHMWPEF, LCP, PBO, PET and other fibers. Applications include composite structural members, three-dimensional laminated components, reinforcements, architectural structures, engineered composites and laminates, and sails.

2 non-woven fabric

AFN Advanced Fiber Nonwovens Company of the United States is a subsidiary of Hollingsworth & Vose, specializing in the production of P-ARF and nickel-plated carbon fiber and CF/GF absorbing nonwoven fabrics, with 5, 8 and 4 varieties. The main applications are lightweight absorbing concealers, large tank and pipe composites, pultrusion pipe surface layers, EMI shielding materials, composite surface materials, honeycomb structure surfaces, integrated circuit board stabilization layers, thermal insulation materials, fuel cells. Component and adhesive substrate.

3 bulletproof composite

The Clemson University and the Army Research Laboratory Weapons and Materials Research Council study the formation mechanism of high specific strength, high specific rigidity continuous P-ARF reinforced resin-based composites, including process parameters including molecular chains, microfibers, and fibers. , yarns, fabrics/layers, single laminates, overlay laminates and laminates (Figure 30). Find the best molding process parameters by simplifying the analysis of the non-linear dynamic/fixed components of the bullet impact scheme.

The US Army Research Laboratory has been engaged in research on the threat of soldiers' protective weapons, including the characterization of dynamic properties of P-ARF and UHMWPEF materials, material dynamics modeling and simulation, synthesis and characterization of nanomaterials, configuration and characterization of polymer matrix materials, and brain. Characterization of neuropathy affected by embossing and blasting, high-performance computational simulation of bone and soft tissue in high-speed damage mechanisms by weapons, physical characterization of bone and soft tissue. In addition, 10 related application studies have been carried out with the aim of further reducing weight, improving protection, reducing costs and expanding application areas. Fibrf lex is a manufacturer of composite materials such as P-ARF, CF, GF, reinforced N-6, N-66, PPS, PEEK, ABS/PC, PEI, PP, FEP, etc., used in drones and weapon parts. Wait.

It is worth mentioning that the basic and applied research on the bulletproof and high-pressure vessels of the series of high-performance aromatic heterocyclic amide copolymer fibers of Russia SVM, ARMOS, RUSAR, ARTEC, etc. have also achieved significant results, in order to promote the development of aerospace and defense military. Contribute.

China's aramid III has been produced in small batches with a total capacity of 450 t/a, contributing to the work of the National Defence Force, but the product replacement is not as good as Russia.
