It is expected that the use of renewable raw materials can give a substantial impulse for a sustainable society. Natural Fiber Composites can provide an alternative for increasingly scarce raw materials.
Product designers play an important role in setting new aesthetic values, presenting materials in different contexts and forms, with different properties. Design research can facilitate this process by providing insights about the user-material-product interrelationships in the attribution of the desired meanings to materials.
Natural Fibre Composites
There are a number of plant fibres in the world (such as abacá, bamboo, cane, coir, corn, cotton, flax, etc.) processed into long continuous threads mainly for weaving and textile production; or chopped as a filler material and combined with a resin to create Natural Fibre Composites (NFCs).
The use of natural fibres particularly within composite materials is predicted to be a growth market as the technical and environmental properties of NFCs, their cost, formability with low investment and straightforward technology make these materials suitable for various applications.
“The use of natural fibres particularly within composite materials is predicted to be a growth market”
In addition to that, NFC materials have unique aesthetic properties which might facilitate the creation of particular user experiences aimed by designers.
In order to give an impulse to the use of Natural Fibre Composites in product design, The Faculty of Industrial Design Engineering (TU Delft) has initiated the foundation of a knowledge platform supported by The Dutch Government (AgentSchap NL): NFC Design Platform.
The platform organized two successful events with high interest from material suppliers, manufacturers and product designers. The 3rd NFC Design Event was held on 16 May2012. Below, the approach of the platform to create awareness on NFC materials among product designers is shortly explained. Snapshots from the organized events and results of a master graduation project conducted with the support of NFC Design Platform are presented.
1st NFC Design Event (April 2011): DESIGN IT !!
The 1st NFC Design Event aimed to introduce the knowledge platform linking material scientists-, manufacturers and designers. After presentations on the NFC potential for design applications in the morning session, participants attended to the ‘Meanings of Materials’ Workshop facilitated by Dr. Elvin Karana in the afternoon.
In the workshop, designers were provided with basic information regarding the varieties of NFC materials through material samples and applications. Provided samples presented a diversity of sensorial and technical properties and exemplified different manufacturing processes to assure that designers get an overview of possible manufacturing processes applicable to NFC materials. The workshop was given in a creative game format encouraging designers to think about different applications for NFC materials. At the end of the workshop, around 100 product ideas for NFC materials were created by participants.
2nd NFC Design Event (April 2011): MAKE IT !!
The focus of the 2nd Event was to experience the NFC materials with different manufacturing processes. After presentations on various production techniques and on technical properties of NFC materials, in the afternoon, participants attended to the ‘Make It Workshop’ where they made simple products by injection moulding, resin transfer moulding and compression moulding.
Layer Chair by Jorrit Taekema
Jorrit Taekema is a recent graduate from Industrial Design Engineering, TU Delft. He completed his master project on ‘NFC Materials in Design’. His main aim was to design a NFC product which shows the properties and potential of the material, which creates awareness on NFC among Dutch Designers. Inspired by Cocolok®, which is a resilient material based on natural cocos fibre bonded with 100% natural latex, developed by Enkev, Jorrit designed his Layer Chair referring to the different layers in nature.
While experimenting with the Cocolok® material, Jorrit came up with the idea of using the same material both as a ‘hard structural/inner element’ and soft ‘outer cushion’ by compressing the material in different degrees. After making a number of tests concerning the strength and durability of the material, he developed his chair. Following pictures shows steps in the process.
