  1. 1. Framework for cost and weight efficient conceptual design of automotive composite body structures

    University dissertation from KTH Royal Institute of Technology

    Author : Per Mårtensson; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; composites automotive cost weight body structure; Aerospace Engineering; Flyg- och rymdteknik; Fiber- och polymervetenskap; Fibre and Polymer Science; Transportvetenskap; Transport Science;

    Abstract : The automotive industry is facing a great challenge - reducing the weight of their vehicles. Carbon fibre composites are regarded by many as the only real option as traditional engineering materials are now running out of potential for further weight reduction. READ MORE

  2. 2. Assessment of Aircraft Radar Cross-Section for Detection Analysis

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Björn Persson; KTH.; Försvarshögskolan.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerospace Engineering; Flyg- och rymdteknik; Försvarssystem; Military Technology;

    Abstract : Att kunna gömma sig för att sedan överaska sin motståndare är en taktik som har använts inom krigsföring genom historien, detta var också en möjlighet flygplan erbjöd när de började användas i militära samanhang. Utveckling av teknik för militära ändamål är emellertid en ständigt pågående kamp mellan framsteg inom det befintliga teknikfältet och utveckling för att kunna motverka sådan teknik. READ MORE

  3. 3. Damage Tolerance of Impacted Composite Sandwich Structures

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Moeen ud din Saeed Rajput; KTH.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; composite sandwich; cellular; polymer; material characterization; modulus; non-crimp fabric; low velocity impact; vibration; uncertainty analysis; drop-weight impact; fractography; barely visible impact damage; X-ray microtomography; compression-after-impact; bending-after-impact; high speed image processing; damage resistance; damage tolerance; Aerospace Engineering; Flyg- och rymdteknik;

    Abstract : This thesis deals with damage tolerance of impacted sandwich structures for load bearing applications. Composite sandwich structures find wide application as lightweight solutions in aerospace components, since weight reduction and less fuel emissions are primary concerns for aircraft manufactures.

  4. 4. Contributions to Variable Fidelity MDO Framework for Collaborative and Integrated Aircraft Design

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Zhang Mengmeng; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerospace Engineering; Flyg- och rymdteknik;

    Abstract : The thesis develops computational tools for early stages of the aircraft design process. The work focuses on a framework which allows several design teams concurrently to develop a baseline concept into a configuration which meets requirements and whose aerodynamics has been assessed by flight simulation.

  5. 5. Towards defect free forming of multi-stacked composite aerospace components using tailored interlayer properties

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Per Hallander; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon Fibre; Composites; Prepreg; Forming; Aerospace Engineering; Flyg- och rymdteknik;

    Abstract : Use of lightweight materials is an important part of reduction of fuel consumption by commercial aircraft. A considerable number of structural aircraft parts are therefore built of thin layers of epoxy pre-impregnated carbon fibres stacked to laminates. READ MORE
