This paper presents a computationally based methodology arising from the application of weaving techniques for the design and construction of an experimental architectural system, Weaving Enclosure. The research explores the close correspondence between material properties and assembly systems found in the traditional craft of weaving, studied through analytical and laboratory tests, and then implemented through computational design and digital fabrication. The workflow for the generation of specific geometries related to the elastic nature of the material results in the design and fabrication of a selfstanding interior partition with digitally conceived patterns, tuned parametrically to provide structural and screening performance.

Este artigo tem como intuito apresentar um trabalho baseado em uma metodologia computacional e os resultados decorrentes da aplicação de técnicas de tecelagem para a construção de um sistema arquitetônico experimental, o Weaving Enclosure. A pesquisa explora a correspondência entre as propriedades do material e a montagem de sistemas encontrados em cestos trançados tradicionais, estudados através de ensaios analíticos, de laboratório e, realizando análise de elementos finitos com processo de trabalho algorítmico. O objetivo é explorar como ampliar o conhecimento obtido através de uma relação milenar entre o homem e a tecelagem sob a perspectiva do design contemporâneo sob as técnicas de fabricação. Com essa finalidade, foi introduzida uma série de experimentos computacionais e simulações para destacar a integração da materialidade, morfogênese digital e fabricação. O artigo apresenta um processo de design para a geração de geometrias específicas relacionadas com a natureza flexível do material e a simulação do seu comportamento com base nas condições ambientais variáveis. Os resultados deste método mostram o projeto e a fabricação de uma divisória, que destaca as propriedades de padrões digitalmente concebidos, definidos parametricamente para oferecer resistência estrutural e anteparo visual. A interação entre técnicas digitais e artesanais para materiais naturais representa um campo promissor para diminuir o impacto ambiental da indústria da construção. No entanto, novos sistemas de montagem, tais como a tecelagem com madeira parecem ainda não ter sido explorados em termos de características performativas e tectônicas que destacam importantes descobertas quando abordadas como um processo de design e fabricação orientada ao material.
Weaving Methods in Architectural Design
ACADIA proceedings
In an effort to investigate surface logics consisting of highly porous, irregularly defined weaving systems a series of investigative strategies were employed. This paper discusses certain modes of research and their derivatives through a case study, Spülenkorb, as an entry into a digital fabrication competition by Texfab, in which the project received honorable mention. The initial form is conceived as a Möbius band, a geometrical variant of the pure mathematical "strip". The base mesh of the initial form is developed using the software TopMod3D and Maya. This base mesh is then processed into a woven object using internally developed weaving software. Knots and links are interesting structures that are widely used for tying objects together and for creating interesting shapes such as woven baskets. To topologists, a knot is a 3D embedding of a circle and a link is a 3D embedding of more than one circle. We prefer to use the general term link, since each component of a link is also a knot. Mathematical links can be used to represent weaving structures such as a fabric, a cloth, or a basket. While there are a wide variety of weaving methods, the most popular is plain-weaving, which consists of threads that are interlaced so that a traversal of each thread alternately goes over and under the other threads (or itself) as it crosses them.

Today’s possibility to design the performance of fabrics thanks to computational tools has broadened the application of knitting techniques to AEC. This paper will introduce a practical and computational trial to produce a knitted shading structure for a pavilion through a preliminary experimental process. The first part of this paper will focus on the practical knitting technique, in which the geometry and derived properties of a knitted stitch will be examined. A rule is defined within the knitted pattern to increase the number of stitches per course, resulting in diagonal outer edges with specific slope. Using this rule, three distinct geometric textile modules are defined where the relationship between the edges of each module provides the possibility for their combination into different patterns. The second part of this paper will introduce possible pattern simulations of the combination of textile modules. Varying degrees of enclosures can be produced through the pattern simul...

This paper outlines a methodology that enables the construction of complex surface forms resulting from computational design processes by manual means using non-industrial materials. The methodology is based on the craft process of weaving whereby a three-dimensional form can be pro- duced using a flexible, linear material. Construction information from a three-dimensional digital model is communicated to craftspersons through a set of two-dimensional drawings outlining the sequence of construction and requiring only linear dimensions.
Development of a finite element model for the weaving process
Due to advancements made in 3D weaving process and, in order to develop 3D textile structure as reinforcement of composite material for aeronautic application, a good prediction of the geometry and the mechanical properties of the 3D woven unit cell is required. The aim of the proposed study is to “numerically” mimic the motions of the main mechanical parts of the loom, including the reed and the heddles, that strongly influence the geometry of the textile architecture in order to produce virtual textile samples that match the real ones.
Force-Driven Weave Patterns for Shell Structures in Architectural Design, 2018
The use of lightweight carbon fiber reinforced polymers (CFRP) in the discipline of architecture opens new possibilities for the construction of architectural components. CFRP has been explored mainly in engineering fields, such as aeronautics, automotive, ballistic and marine engineering. CFRP has also been explored in the discipline of architecture in the construction of shell structures because of its high strength-to-weight ratio and low-cost. There is, however, limited research on how structural analysis can be used to inform weave patterns for shell structures using CFRP. Further, previous research in the field has not performed physical structural tests to validate which force driven weave patterns perform best. This thesis addresses this gap by contributing a methodology for the creation of CFRP weave patterns from structural analysis and their validation through physical testing. Specifically, this thesis addresses three main problems: Firstly, understanding and analyzing the structural behavior of a shell structure through computation; Secondly, the creation of a weaving pattern of carbon fiber optimized for structural performance; the third part seeks to translate the digital model into fabricated prototypes. The results of this research show that force-flow derived patterns perform best. Consequently, force-flow is the information we should implement to create a more efficient force-driven weave pattern in shell structures.
CAD/CAM of three-dimensional woven structures (preforms) for fibre-reinforced composites
Composites Part A: Applied Science and Manufacturing, 1996
The weaving of virtually endless three-dimensional preforms where the height and width are of similar magnitude (e.g. 50 x 50 cm) on a conventional loom is described. The term 'conventional loom' refers here to any kind of two-dimensional weaving machine, irrespective of whether it uses a shuttle or is shuttleless. A software package has been developed which enables complete weaving instructions to be generated that can automatically control the operation of an electronic Jacquard machine. The principles applied in developing the software are described under two broad headings, i.e. the flattening of the preform so as to make it weavable on a conventional loom and the selection of the shuttle paths on which the weaving instructions are based. Weaving experiments based on these principles are reported. Theoretical and practical work is also described for producing preforms where two sets of threads are inclined to each other by an acute angle so that they could be orientated in the direction of the anticipated maximum stress.
