Diolen Polyester Fibre is a low density (1.3g/cm3), high tenacity fibre which has good impact characteristics due to it's very high elongation and break, however, the young modulus is very low. It is used in applications where high stiffness is not a requirement, but where low weight, high impact resistance and high abrasion resistance is important.
Diolen is commonly used in the manufacture of Canoes and Kayak's and many more applications where high impact strength is important.
Diolen can be between layers of chopped strand matting to achieve a rigid structure which has very high impact resistance, as an example Diolen has been incorporated in the manufacture of lifesaving equipment, what tends to happen is the glass fibre will break, but the Diolen will absorb this impact and more or less spring back into shape. It is essential it is sandwiched between layers of glassfibre matting for maximum strength, or effectively laid on the reverse of a laminate, which is usually apparent in canoe/kayak construction.
With a Resin: Diolen ratio of 1:1 , i.e 1 mt of 265g Diolen will use 265g of Resin.
