Liquid composite moulding of Lactam 12 monomer and activating system (APLC12) into satin weave carbon fabrics is investigated, with emphasis on minimising the void content in the final part. The main sources for void formation are identified. The solidific ...
The aim of this work is to integrate polypropylene/montmorillonite (MMT) nanocomposite matrices into conventional fibre-reinforced composites. Two types of composite have been considered: long fibre-reinforced composites from co-woven glass fibre and nanoc ...
A process for making hollow composite structures or vessels which includes the steps of: A) heating a mixture of thermoplastic matrix and reinforcing fibres wrapped over a rigid or semi-rigid thermoplastic liner or bladder above the melting point of the th ...
The influence of the initial configuration of glass mat and polypropylene on the deconsolidation during post-processing of the resulting composite is investigated. Deconsolidation experiments of a classic type of glass mat reinforced thermoplastic (GMT) pr ...
During reheating and post-processing of thermoplastic-based composites, deconsolidation is often observed: the volume fraction fibre decreases and the void content increases. In this article, the phenomena leading to deconsolidation are investigated, with ...
Chiral esters and amides (I) of pyrrolidine-2-carboxylic acid are new. - Chiral esters and amides of pyrrolidine-2-carboxylic acid, having formula (I), are new. - A = groups F1 or F2; - R' and R'' = 1-20C hydrocarbyl, i.e. acyclic, linear or branched, satu ...
Although biopolymers and synthetic polymers share many common features, each of these two classes of materials is also characterized by a distinct and very specific set of advantages and disadvantages. Combining biopolymer elements with synthetic polymers ...
The low-pressure cold microwave (MW) plasma is shown as an efficient method to increase acidity of the ACF within less than 1 min treatment without affecting the fiber morphol. and strength. The ion-exchange capacity was 1.6 times higher compared to the no ...
Unsaturated Polyester (UP) resins are extensively used as a matrix for the production of composites due to their low cost and versatility. Their significant polymerization shrinkage has however a negative impact on the dimensional stability of the molded p ...
The ionic liquid 1-dodecyl-3-methylimidazole chloride ([C12- mim]Cl) is doped with 1 mol-% of the lanthanide ternary complexes [Ln(tta)3(phen)] (tta = thenoyltrifluoroacetonate, phen = 1,10-phenanthroline, Ln = Nd, Eu, Er, Yb), resulting in luminescent mes ...
