This chapter gives an overview of Quickstep processing method, which is relatively a new technique for manufacturing composites. In this chapter, different aspects of Quickstep processing are highlighted. Since Quickstep processing is an Out-Of-Autoclave (OOA) technique, a brief description of autoclave processing is provided. Basic principle of Quickstep processing and functionality of typical Quickstep plant are also explained. Due to changed chemo-rheology, methodology for cure optimization of different prepregs and composites are discussed with examples. This chapter also includes the literature survey of different aerospace materials being investigated in Quickstep, the potential of new materials development for this process, the melding technique, in service capabilities of Quickstep cured samples and journey of Quickstep from patent to commercialization. Although the technique is commercialized now, few suggestions in the end are provided for the improvement of process.

Hydrolysis Of

A new technique is described which allows the quantitative exchange of copper(II) into ZSM-5 zeolites. The sequence consists of two steps: (i) impregnation of the zeolite with copper(II) in amounts higher than the exchange capacity; (ii) leaching of the copper in excess with respect to the exchange capacity with a chlorobenzene-water mixture at high temperature. The performances of the new materials in the hydrolysis of chlorobenzene, as well as preliminary informations on the nature of the catalyst and the type of mechanism are presented.

Gradient Variation

This work deals with a novel processing method that combined extrude with laminate molding for preparing polymeric graded material (PGM). The variations of inhomogeneous property were generated by altering the feeding speed and/or weight ratio of the components as well as changing the order or numbers of the folded layers. Three modes of polypropylene (PP)/ talcum powder (talc) flat PGM (signed with T1, T2, T3) are fabricated successfully by using this new technique. The preparation, structure and property of the resultant PP/talc graded composite were investigated. Results indicate that the composition, morphology and properties show a gradient variation along their thickness direction of the flat PGMs.
