Thermal Rheological Analysis of Cure Process of Epoxy Prepreg
The cure process of epoxy prepreg used as composite pipe joints was studied by means of differential scanning calorimetry (DSC), Bohlin Rheometer and other techniques. Isothermal DSC measurements were conducted between 110 and 220 C, at 10 C intervals. The results show that the complete cure reaction could be achieved at 220 C. The isothermal cure process was simulated with the four-parameter a...
متن کاملComparison of Compressive Properties Between Va-cuum Infusion and Hand Lay-Up Method Toward Bal-sa Core Sandwich Composites
The aim of this work is to evaluate the influence of fabrication methods on the com-pressive properties of sandwich composites using both experimental work and numerical simulations. Two types of sandwich composites with E-glass/Kevlar/polyester resin facings and End-grain balsa wood as core have been produced by vacuum infusion processing (VIP) and hand-lay up (HL) method. Compression tests on...
متن کاملCharacterisation and Control of Fibre Alignment during Prepreg Manufacture
A procedure is presented for characterisation of fibre misalignment in composites. It is based on analysis of low magnification images in which the local fibre direction can be inferred from the orientation of elongated features in the image. Specimen preparation and image analysis procedures are presented and their usage is illustrated by application to a carbon fibre composite. Factors affect...

متن کاملOpening Up the Policy Process
The tax debate has placed the Senate in an unfamiliar relationship with the executive. On the one hand, there are the habits and practices of governance of roughly the past 80 years. Throughout this period, the executive has enjoyed almost unchallenged power. The rituals of Parliament have positioned the Opposition as an alternative government rather than as legislators. This is implicit in the...
