1 ADVANCED COMPOSITES AND ORGANO SHEETS

2 GIVIDI FABRICS manufactures Technical Fabrics in one of the most advanced weaving facilities in the world; founded in 1962, today the company has a state-of-the-art technological production structure and has an installed annual capacity of more than 30 million square meters of fabrics. GIVIDI FABRICS produces the highest quality technical fabrics for your most demanding applications based on E glass, High Modulus R glass and High Strength S glass, Aramid fibers, other High-Strength/High-Performance fibers and Hybrids. Thanks to our long experience and knowledge of high performing fibers as well as to our extensive R&D facilities and capabilities, we are proud to provide the resources and expertise for innovative solutions to meet evolving customer needs. GIVIDI FABRICS produces also reinforcements treated with several weave-set types, including thermoplastic matrices, ideal for preforming and stabilisation as well as for emerging Organo-sheets applications. GIVIDI FABRICS is a serious, efficient, reliable and technologically advanced Italian company part of GIVIDI Group. The quality of its products, the quest for continuous improvement and a passion for innovation characterize GIVIDI FABRICS activity and have contributed to make GIVIDI FABRICS an undisputable reference point in its market segment by delivering high quality innovative solutions that maximize value for the customers. For more than 50 years GIVIDI FABRICS products have been used in composites application, from racing boats and cars to luxury yachts; today GIVIDI FABRICS reinforcements are used in several advanced composite applications in commercial Aerospace, Railway and Automotive programs. Technical reinforcements from GIVIDI FABRICS are available in a wide range of weights, weave patterns and fibers. They provide mechanical strength, stiffness and weight reduction possibilities compared to other materials. Depending on the technical requirements of the end product, GIVIDI FABRICS can develop reinforcements leveraging each fiber type unique characteristics as well as choosing the best weave construction and pattern to maximize the mechanical performance of the reinforcement in Customer s application. GIVIDI FABRICS unique knowhow and experience in surface chemistry, gathered in its long history as a leading producer of reinforcement for electronics applications, particularly for High Frequency resin matrices with the most stringent performance and quality requirements, has led to the development of Finish recipes and processes for high temperature resistance, excellent wet-out and best resin compatibility for the production of void-free prepregs and parts. Specific Finishes have been developed for Low Dk resin systems used in High Frequency applications like HF PCBs, Antennas and Radomes. GIVIDI FABRICS Fiber Spreading Technology can be applied to reinforcements to minimize porosity, enhance wet-out for more homogeneous, thinner composites. GIVIDI FABRICS products are intrinsically technical products and therefore all of our Sales Team members have a Technical background to be able to provide technical insight from the very beginning of any inquiry. This, together with our Technical and R&D teams, contributes to deliver unequalled sales and technical Service to our customers both before and after sales.

5 WEAVE-SETS Since many years, GIVIDI FABRICS has been developing several weave-sets to stabilize its fabrics and woven rovings to improve handling, adhesion properties and other functionalities as well as to reduce material waste and manufacturing cycles in customers processing. By selecting the most appropriate resin matrix and resin content (3-15%) for customers applications, GIVIDI FABRICS weave-set reinforcements significantly enhance the performance of the end product. sets can be based on Acrylic, PU, Epoxy, Polyester and several other types of polymers and copolymers; different colours are also available. * Resin Content** WEAVE SET FABRICS End Count [yarns/cm] Yarn Tex Final Weft [grams/sqm] 290 ST 290T 3%- 15% Twill 2/2 5,3 4,3 300 Tex Roving 300 Tex Roving VR 48 3%- 15% Twill 2/ x EC 9 68 EC VR 181P 3%- 15% 8H satin EC 9 68 EC ST 320 3%- 15% Plain or Twill 5,3 5,3 300 Tex Roving 300 Tex Roving VR 136 3%- 15% Plain or 4H Satin 19 9 EC EC VR 391 3%- 15% Twill 2/2 6 6,7 5 x EC 9 68 EC * these are main styles only but several other styles can be offered with weave-sets ** Resin Content varies depending on the requirement of customers application ORGANO SHEETS In recent years, continuous fiber reinforced thermoplastic semi-finished composites, commonly referred to as Organo Sheets, have quickly become of increasing interest in Advanced Composites applications due to their combined advantages in processing (shorter cycle times), good impact strength, possibility of high level functional integration and overall lower cost compared to thermoset parts. GIVIDI FABRICS has recently developed Organo Sheets based on PA, PP, TPU and other thermoplastic resin systems both for direct forming or for the increasingly popular forming with back injection molding; choosing the right reinforcement and thermoplastic resin in conjunction with back injection molding may enable the integration of details like localized targeted reinforcement, mounting holes or other features further reducing the overall cost of the finished part.
