A comparative thermoacoustic insulation study of silica aerogels reinforced wit...
Linhares, Teresa Conceição Amaral; Carneiro, Vítor Hugo Pimenta; Amorim, M. T. Pessoa de; Durães, LuisaSilica aerogels are highly porous materials with exceptional thermal insulation performance. They become even more attractive if combined thermal and acoustic insulation is achieved. Silica aerogel composites reinforced with fibres are an ingenious way to surpass the fragility stemmed from the aerogel’s intrinsic porosity, and textile fibres are good sound absorption materials. Reclaimed fibres are a relatively...
Enzymatic enhanced adhesion of cellulosic woven fabrics composites
Linhares, Teresa Conceição Amaral; Zille, Andrea; Soares, Graça M. B.The purpose of this work was to produce and characterize enzymatically treated fabric composites using different mixture of two commercial cellulase enzyme solutions in dosages of 0.1% and 0.5% in order to improve fabric’s adhesion. Three cellulosic taffeta plain weave fabrics of 100% flax, cotton and bamboo viscose were used in different combinations. The properties of the woven fabrics and produced composites...
Enzymatically enhanced adhesion of cellulosic woven fabrics composites
Linhares, Teresa Conceição Amaral; Zille, Andrea; Soares, Graça M. B.This work intended to study the production of composite using enzymatic modified woven cellulosic fabrics made up from fibres of cotton, linen and bamboo viscose. The adhesion of the fabric will be promoted using different mixture of cellulase enzymes. The properties of the woven fabrics and produced composites were characterized using several physical tests. The cotton & viscose composite appear to be the best...
