preparation example Construction

[0050] 1) Preparation of continuous rolls of single-oriented prepreg tape without liner

[0051] The high-strength and high-modulus fibers are placed on the parallel wire frame, and the fiber tows are evenly spaced under the drag of the tractor. The high-strength and high-modulus fibers are synchronously fed into the friction roller device, and the high-voltage static electricity is carried by the static friction fibers. Under the action of electrostatic force, they repel each other and achieve a uniform arrangement state; the fibers are dipped and scraped, and the adhesive is cured and formed, so that the single orientation of the high-strength and high-modulus fibers is maintained in a uniform state, and the single orientation of the unlined film fiber is obtained under further drying. Continuous rolls of prepreg tape;

Embodiment 1

[0081] Production of continuous rolls of mono-oriented prepreg tape without liner

[0082] Place ZTX99 about 600d (240f) high-strength high-modulus polyethylene (HSHM-PE) fibers (breaking strength ≥ 35cN / dtex, modulus ≥ 1100cN / dtex, elongation at break ≈ 3%) on parallel wire racks. The fiber tow is dragged by a seven-roller tractor, passes through a reed of 5 reeds / cm, and is evenly spaced within a width of 1.20M, and the fibers are synchronously fed into the friction roller device. Under the drag of the rear tractor, the fibers carry high-voltage static electricity through static friction, and the monofilaments in the bundle of fibers repel each other under the action of electrostatic force to achieve uniform arrangement, and then dipped in glue through the dipping roller (adhesive is styrene-ethylene-butylene) -Styrene polymer (SEBS), styrene-ethylene-ethylene-propylene-styrene polymer (SEEPS) or a mixture of the two as the main solvent-based adhesive, the adhesive content i...

Embodiment 2

[0084] Preparation of Continuous Coil of Two-layer Orthogonal Composite Mono-Oriented Prepreg Tape Without Liner Film

[0085] The continuous roll of the single-oriented prepreg tape without liner film in the embodiment was cut into a 1.20M square sheet for subsequent orthogonal compounding.

[0086] Repeat the operation of Example 1. After the single-oriented fiber is dipped, the adhesive is not yet dry. The 1.20M square sheet is superimposed and bonded in the form of adjacent two-layer fiber orientation orthogonal, and then pressurized in the rolling compound machine. Composite, achieve [0 / 90] orthogonal online composite, become [0 / 90] two-layer orthogonal composite single-oriented prepreg tape continuous coil without liner film.

Abstract

A soft stabproof bulletproof material is in a sandwich structure formed by intersecting and compounding a plurality of layers of fiber unidirectionally-orientated prepregs, wherein one of at least one bulletproof stabproof layer comprises three basic units, each basic unit is formed by orthogonally compounding high-strength high-modulus fiber unidirectionally-oriented prepregs, intersection angles 0-90 degrees of adjustment units are superposed and compounded, and organic films are adhered to two sides of each layer through block adhesive. The invention further discloses a method of preparing the soft stabproof bulletproof material. Favorable stab proofing of the soft stabproof bulletproof material is maintained while bullet proofing of the soft stabproof bulletproof material is improved. The soft stabproof bulletproof material can be used independently or used with other materials to apply to making of multi-specification bulletproof stabproof garments. The soft stabproof bulletproof material light in weight and fine in defensive performance can be continuously rolled on a large scale.

Description

technical field [0001] The invention relates to a soft stab-proof and bullet-proof material. [0002] The invention also relates to a preparation method of the soft stab-proof and bullet-proof material. Background technique [0003] Gunshots and knife stabs are two major threats to human injury. Gunshots or knife stabs are often unpredictable for individual defenders. Therefore, it is very necessary for individual equipment to have both stab-proof and bullet-proof functions. However, the mechanisms of stab resistance and bullet resistance are very different, and it is very difficult for materials to take into account both functions at the same time. [0004] People have made some discussions on the puncture of the protective P knife (see Textile Research Journal vol76 (8) 607-613 for details), pointing out that the sharp knife tip has a great puncture ability and the sharp knife edge has a great cutting effect on the material. Research has been carried out around the follo...
