WOVEN MULTI-LAYER FABRICS FOR USE WITH NON-BALLISTIC THREATS
A multi-layer woven fabric, including an upper woven layer having upper warp yarns and upper weft yarns that are interwoven together to form the upper woven layer. The cover factor of at least one of the layers is selected so as to inhibit penetration by non-ballistic threats
Reformable Resin Filaments and Materials Formed Therewith
The present teachings contemplate forming a reformable epoxy resin material into a monofilament having a denier of from about 50 to about 5000 and a glass transition temperature of less than about 200° C.; loading one or more monofilaments onto a spool; co-weaving the one or more monofilaments with a reinforcing fiber to form a woven material, the reinforcing fiber having a glass transition temperature of greater than 200° C.; heating the woven material to form a composite to a temperature so that only the one or more monofilaments soften but the reinforcing fiber does not.
FIBER TEXTURE FOR A CASING MADE OF COMPOSITE MATERIAL WITH IMPROVED IMPACT RESISTANCE
A strip-shaped fibrous texture has a three-dimensional or multi-layered weaving between a plurality of layers of warp yarns or strands and a plurality of layers of weft yarns or strands extending in the lateral direction. The fibrous texture includes a first section extending along the longitudinal direction from a proximal portion of the texture and in which one or more layers of the plurality of layers of weft yarns or strands consist of a plurality of groups of yarns or strands each including at least one carbon fiber yarn or strand and one glass fiber yarn or strand. The carbon fiber yarn or strand and the glass fiber yarn or strand of each group of yarns being woven together according to the same weaving pattern or weave. The fibrous texture further includes a second section present between the first section and a distal portion of the fibrous texture.
Ballistic resistant thermoplastic sheet, process of making and its applications
Woven fabrics are formed from high tenacity fibers or tapes that are loosely interwoven with adhesive coated filaments, to composite articles formed therefrom, and to a continuous process for forming the composite articles.
Material sheet and process for its preparation
Material sheets are provided which include at least one monolayer, wherein the at least one monolayer has a plurality of drawn unidirectional polymer fibers having a strength of greater than 1.2 GPa and a thickness of less than 100 μm, and wherein the material sheet includes a bonding agent of less than 13 wt % relative to the total weight of the material sheet.
Rigid ballistic composites having large denier per filament yarns
A rigid ballistic-resistant composite includes large denier per filament (dpf) yarns. The yarns are held in place by a resin to form a rigid composite panel with improved ballistic performance. The large dpf yarns may be selected from aromatic heterocyclic co-polyamide fibers, polyester-polyarylate fibers, high modulus polypropylene (HMPP) fibers, ultra high molecular weight polyethylene (UHMWPE) fibers, poly(p-phenylene-2,6-benzobisoxazole) (PBO) fibers, poly-diimidazo pyridinylene (dihydroxy) phenylene (PIPD) fibers, carbon fibers, and polyolefin fibers.
High lap shear strength, low back face signature UD composite and the process of making
Fabrication of ballistic resistant fibrous composites having improved ballistic resistance properties. More particularly, ballistic resistant fibrous composites having high interlaminar lap shear strength between component fiber plies or fiber layers, which correlates to low composite backface signature. The high lap shear strength, low backface signature composites are useful for the production of hard armor articles, including helmet armor.
FIBER TEXTURE FOR A CASING MADE OF COMPOSITE MATERIAL WITH IMPROVED SHEAR RESISTANCE
A fibrous texture in the form of a web includes a first portion extending in a longitudinal direction between a proximal part and an intermediate part. One or more layers of warp threads or strands present on the side of an inner face of the fibrous texture include threads or strands of glass fibers, the threads or strands of the other layers of warp threads or strands including threads or strands of carbon fibers. The fibrous texture further includes a second portion extending in the longitudinal direction between the intermediate part and a distal part of the fibrous texture. One or more of the plurality of layers of warp threads or strands present on the side of an outer face of the fibrous texture include threads or strands of glass fibers. The warp threads or strands are continuous over the entire length of the fibrous texture.
Protective mid-cover textiles
A new class of protective fabrics having good ballistic and fragmentary protection also provide wearable drape, softness, and moisture transport, as well as good UV and abrasion resistance and color acceptance, making them comfortable to wear as garment fabrics. The protective fabrics are constructed from yarns having at least 20% ballistic fibers with greater than 12 gpd tenacity. A combined cover factor of between 55% and 80% avoids added stiffness due to yarn distortion at the crossing points. In embodiments, a long-float weave such as twill or satin with reduced crossing point density improves the hand of the fabric, and in some embodiments provides a different character on each face so that a predominantly staple fabric face is in contact with skin of a user, thereby providing better wearing comfort than a plain weave.
RIGID AND SEMI-RIGID COMPOSITES INCORPORATING WOVEN MULTI-LAYER FABRICS
Woven multi-layer fabrics and/or rigid or semi-rigid composite panels incorporating one of more woven multi-layer fabrics all as generally and specifically described herein.
