This paper focuses on the development and the validation of flexural modulus and flexural strength predictive models of long glass fibre reinforced polyamide 6.6 (PA66). Based on previous injection moulding optimization of 40 wt% long glass fibre PA66, a microstructure analysis was investigated on glass fibre reinforced PA66 by varying the parameters of the material (fibre length, fibre content, fibre diameter). In a first phase, analytical models established within the framework of the processing condition limits previously determined have been elaborated. These models lead to a good experimental/calculation correlation but remain limited to a mould and part design. In a second phase the flexural modulus and maximal flexural stress have been then estimated from structural models based on a five layer morphological description of the composites (local residual fibre length, local fibre content and fibre orientations). The long glass fibre PA66 composites were characterized in terms of fibre content distribution model and fibre orientation model through the part thickness. The experimental/model correlation was achieved whatever the process variability is (mould, material and processing conditions) both for the flexural modulus or flexural strength. The models have been then validated with an industrial part. Finally, a correlation between the two studied properties has been revealed depending on the nature of the composite matrix (PA66, PA6 or PP).

Fibre heating can be employed to optimise composite fabrication in hand lamination. In order to show the fibre heating effect on the properties of hand laminated composites, dynamical and mechanical tests were performed on simply cured glass fibre reinforced laminates and on treated ones. In this second case the fibre content was heated before composite lamination by means of a hot parallel plate press. All the specimens were room temperature cured. A significant increase in storage modulus was observed as an effect of fibre heating as well as a data dispersion reduction. Additionally a lower thickness was measured due to the higher resin fluidity.
