  1. 1. Processing and properties of glass mat thermoplastics

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Greger Nilsson; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Abstract : The rapid processing of glass mat thermoplastics (GMT) is well known, large complex parts can be processed in less than one minute. It is however important that the material is produced properly to avoid a reduction in mechanical properties. There are some underlying industrial questions for this work. READ MORE

  2. 2. Fibre orientation and rheological behaviour in compression moulding

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Fredrik C Vahlund; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Compression moulding is a common manufacturing process for composite materials. In order to better predict the processing and performance of components, simulation tools are becoming more important. In this thesis the behaviour of the compression moulding raw material has been studied to provide a platform for better simulations. READ MORE

  3. 3. Glass mat reinforced thermoplastics - material, process and selected applications

    University dissertation from Div. of Production and Materials Eng., Box 118, S-221 00 LUND, Sweden

    Author : Jan Wahlberg; Lund University.; Lunds universitet.; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material technology; recycling; sound absorption; energy absorption; vibrational energy; microtension; processing; Glass fibre; thermoplastics; Materiallära; materialteknik;

    Abstract : The work presented in this thesis covers the processing of glass mat reinforced thermoplastics, GMT, and the mechanical properties of this material group. The thesis evaluates the possibilities of the material group from a processing and mechanical properties point of view. READ MORE

  4. 4. Time-dependent behaviour of fiber reinforced polymeric composites

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Modris Megnis; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Abstract : The presented thesis contains results of experimental and theoretical studies of the time dependent processes in fiber composites. The first part of the thesis is dedicated to unidirectional fiber reinforced composites. Glass fiber laminates are tested and analyzed. READ MORE
