Weaving is a textile production method that uses a loom to interlace two sets of yarn at right angles. To create fabric, the lateral yarn, called the weft, repeatedly crosses with the longitudinal yarn, referred to as the warp, which is held taught by the loom.
The process of weaving can be summarized in three steps:
Shedding — The warp ends are separated to clear a space for a pick
Picking — The pick inserts the weft through the shed
Beating — The reed pushes the weft up against the fell of the cloth completing one weave cycle
Although the basic weaving process is the same, the specific method in which the yarn is interlaced and propelled through the shed can change the characteristics of the finished fabric. Popular methods of weaving include the use of:
This conventional loom type – which includes hand looms, non-automatic power looms, and automatic weaving machines – interlaces the weft and warp yarn using a shuttle (usually made of wood). This method can manufacture seamless fabrics and tubular materials, making it suitable for critical applications requiring uniformity. It is slower than shuttleless looms.
This is a loom type which includes needle looms, rapier looms, and water/air jet looms. Its highly efficient operation increases production capacities while reducing large run labor costs. Needle loom models produce material with one woven edge and one knitted edge.
A jacquard loom is a mechanical loom that simplifies the manufacture of complex patterns. Originally controlled by a sequence of hole-punched cards laced together, these looms now operate under CAD systems. They can be labor-intensive to set up initially. Jacquard weaving is a durable, high quality alternative to printed webbing, capable of producing a variety of weaves, designs, and logos from a single warp.

Webbing is a strong woven fabric distinguishable by its assorted material compositions, strength differences, and widths. Appearing across a broad range of applications and industries, webbing can be found in military gear, hiking and camping gear such as harnesses, and automotive safety features like seatbelts.
Once made of natural fibers such as cotton or flax, modern webbing is now usually made of fibers including strands of nylon or polyester woven on a loom to create flat strips. For extreme applications, webbing is even available in high-strength materials such as Dyneema® and Kevlar®.
Types and Properties of Webbing
There are two basic types of webbing, identifiable by their shape and distinct physical properties:
Properties: Available in different breaking strengths, this style can carry out a number of basic applications. While the flat shape is well suited for applications in which material is sewn directly into a larger product, it can be susceptible to abrasion due to its stiffer nature in comparison to tubular webbing.
Tubular webbing – Generally thicker, this type of webbing is known to be more flexible than flat webbing.
Properties: Soft and pliable, this style allows for a variety of uses in comparison to its flat counterpart. It is also less susceptible to wear and tear, and is able to handle dynamic functions, such as holding knots.
Webbing is an adaptable component that appears in a diverse range of applications. Examples of common industries and specific uses include:
Military – Specialized Mil-Spec and PIA-Spec (Parachute Industry Association) narrow webbing is manufactured as Class 1 (critical use, shuttle loom) or Class 1a (critical use, shuttleless / needle loom) to deliver payloads safely and reliably.
Aerospace – High strength specialty webbing appears in parachutes, flight suits, seat belts, cargo netting reinforcement, and crew safety components.
Safety webbing – Webbing enables civilian safety through applications such as chin and shoulder straps, lap belts, harnesses, binding tapes, and shock absorbing webbing.
Commercial webbing –Webbing is found in everyday commercial applications such as backpack straps and pet leashes.

3-D weaving is a cutting edge process that offers consumers joints and other parts with an optimal blend of strength, durability, and structural integrity.
Ideal for use within the aerospace industry, 3-D woven joints are considerably lighter than traditional metal joints without sacrificing exceptional strength and durability. This, unsurprisingly, results in a great deal of cost savings for the aerospace industry and the businesses involved within it.
Three-dimensional weaving offers a range of benefits for consumers, each of which saves cost and enhances product performance. Employing a 3-D woven composite in lieu of metallic structures will offer consumers a material that is lightweight, stronger than its metallic counterparts, and free of corrosion. In fact, the utilization of three-dimensional structures and fabrics may lead to a 30% reduction in aircraft weight and, subsequently, a reduction in total operational costs spent during an aircraft’s lifetime.
Employing a 3-D woven structure is the simplest and most efficient method of incorporating composite parts into future products. 3-D woven composites are produced near-net shape, meaning the composite requires minimal processing to be installation ready. 2-D laminated composites, on the other hand, require a lengthy and technically challenging lamination process. Cutting out the lengthy processes associated with 2-D composite methods means saving energy, time, and, subsequently, money.
3-D woven composites are completed as one piece — they do not require cutting, plying, or stitching, as 2-D laminated composites do, and require minimal machining. Without multiple layers laminated together, 3-D woven composites cannot become delaminated. The inherent inability of 3-D woven composite structures to delaminate is arguably one their greatest advantages. Design flexibility and the capacity to tailor composite properties to specific applications are also crucial 3-D weaving benefits.
Employment of 3-D woven joint technologies can provide enhancements in damage resistance without sacrificing weight. At Bally Ribbon Mills, our advanced products group has developed the technology to 3-D weave intricate net shapes, including pi (π), “T,” double “T,” “H,” and more.
Bally Ribbon Mills has played an essential role in the design, development, and manufacture of specialized products for a range of industries since 1923. We are committed to providing high quality materials with exemplary efficiency.
Discover how 3-D composites create product consistency in the aerospace industry.
Composite parts are specially engineered components made of two or more polymers with different physical and chemical properties. These compositions make up a broad range of aerospace components, including wings, tails, fuselages, and propellers. Though manufacturers have traditionally fabricated compositions with 2-D laminated composite parts, newer 3-D continuously woven structures are becoming the aerospace trend.
Conventional 2-D compositions can present a number of challenges, including structural delamination and cracking, lack of broad use from one project to the next, high costs, and a significant time investment to create the compositions. To remedy these common 2-D problems, manufacturers are now embracing 3-D woven composites, as an improvement to the traditional 2-D joints and a solution to their associated weaknesses.
2-D compositions typically fail manufacturers in two ways: cracking and delamination. In aerospace applications, repeated cyclic stress and impact causes separation and fraying of the composite layers. Unlike solid metals, compositions are weak and unable to contort to absorb kinetic energy. The inability to adjust to this impact creates fractures in the composition’s surface, known as matrix cracks.
Once a 2-D composite begins to develop small transverse matrix cracks, any additional impact will cause them to extend to neighboring plies with different fiber orientations, thus beginning the delamination process. The initial matrix crack that starts this process is called the critical matrix crack. Once this crack has developed, delamination will continue to spread and damage the other composition joints over time.
The higher damage resistance and greater fracture toughness of 3-D woven composites can reduce the prevalence of – or even entirely eliminate – many of these issues. The interlocking 3-D-woven reinforcement gives composite materials stronger out-of-plane properties to protect from warping and delamination.
In comparison to 2-D compositions, 3-D woven composites offer enhanced performance over 2-D alternatives, and the ability to rapidly produce materials using 3-D weaving compresses lead times and reduces overall labor and tooling costs.
Bally Ribbon Mills (BRM) creates these intricate composites using a 3-D continuous weaving technique. With our experience developing quasi-isotropic technology for the US Air Force Research Lab and recently completing a 3-D woven materials contract for NASA’s space flight applications, we are a trusted supplier on the cutting edge of high performance structural composite parts.
After 4 years of intensive collaboration in developing an innovative cryogenic upper interstage composite ring demonstrator for new space launchers, SONACA (Belgium) and BRM (USA) win the JEC 2016 world innovation award in the space category.
The development optimized the cross section of a circular 4.3 meter diameter ring. This resulted in an important weight saving at an affordable price.
The innovation consisted of making the best choice of composite materials and manufacturing processes (Weaving, Injection), validated by suitable simulations and tests, while ensuring the challenging industrial requirements were met (Net shape part, logistics, final assembly). The most advanced 3D orthogonal weaving process was used to produce a demonstrator ring with 90° segments based of carbon fiber dry preforms. Each segment was injected using Resin Transfer Molding process (RTM). The four segments were then assembled together by splicing.
SONACA and BRM signed a partnership agreement to consolidate the progress already achieved in the field of advanced structural composite parts, in order to offer high quality and competitive advanced composite structures to their customers.
