  • Improve the locally manufactured billets after homogenizing to match with imported billets 
    Sankalpa, PVG; Welathanthri, SL; Guluwita, SP [Conference-Abstract]
    6xxx series aluminum alloys have a combination of medium strength, good corrosion resistance, excellent formability, good weldability, easy recycling and especially good heat treatability. AA 6063 alloy is the most widely ...
  • Investigation of applicability of coconut shell powder as a filler in natural rubber composites 
    Athauda, AARS; Chathuranga, G; Liyanage, NMVK [Conference-Abstract]
    Applicability of coconut shell powder(CSP) as a filller in natural rubber(NR) based composites was investigated. Incorporation of CSP into NR composites was done in two different forms; crude CSP, purified CSP, either ...
  • Investigation of laser scribing technique for graphite oxide reduction and patterning 
    Prasath, M; Jayasinghe, JGDSD; Attygalle, D [Conference-Abstract]
    Engineering a low cost graphene-based electronic device has proven difficult to accomplish via a single-step fabrication process. An infrared laser assisted technique to reduce graphite oxide (GO) to graphene, at ambient ...
  • Microcrystalline cellulose based polymer composite for engineering applications 
    Rajapaksha, LD; Saumyadi, HAD; Samarasekara, AMPB; Amarasinghe, DAS [Conference-Abstract]
    In the last several years, polymer composites have been used heavily in aerospace, automotive and other engineering applications. Polymer matrix composites (PMCs) are comprised of a variety of short or continuous fibers ...
  • Nondestructive evaluation of corrosion damage in concrete reinforcement bars 
    Maddumahewa, KK; Madusanka, NPA; Sivahar, V [Conference-Abstract]
    Corrosion of reinforcement bars which are embedded in concrete is one of the significant problems encountered in reinforced concrete structures. Despite the fact that concrete gives protection against corrosion, ...
  • Preparation of wood-plastic composite using teak saw dust and high density polyethylene 
    Wimalaratne, BAPM; Madushan, WKR; Udayakumara, SV [Conference-Abstract]
    Wood-Plastic composites are materials made out of wood (Fibers, particles. dust, etc..) and thermoplastic materials (PP, LDPE, HDPE, etc...). From Recent history wood-plastic composites have an increase in popularity due ...
  • Removal of mercury from dental wastewater 
    Abeysiri, NKDS; Kumarasinghe, KAMM [Conference-Abstract]
    Industrial waste, especially heavy metals such as mercury, have generated a significant threat to public health due to their toxicity and persistence in the environment. These effluents should be treated well before ...
  • Rubber based strain sensor for detection of tyre and road conditions 
    Karunarathna, NPM [Conference-Abstract]
    Detection and measuring of larger strains as those exist in rubber components has long been a requirement that had met with limited success. Compared to traditional metallic strain gauge, elsatomer based strain sensors ...
  • Solar powered mini air conditioner for automobiles 
    Gunawardhana, HPB; Chamath, LG; Galhenage, AS [Conference-Abstract]
    As a tropical country, Sri Lanka experiences sunny conditions throughout the year. Most of the time vehicle users find it difficult to obtain shady places for their parking purposes. The temperature rise of the automobiles ...
  • Study of the dielectric behavior of graphite oxide upon exposure to chlorine 
    Silva, SM; Kulathilake, PHD; Attygalle, D; Amarasinghe, DAS [Conference-Abstract]
    Graphite Oxide (GO) was synthesized using the Improved Hummer’s Method. After the successful synthesis of GO, it was characterized and its dielectric properties were investigated. The change of dielectric behavior of GO ...
  • Thermoplastic polymer modified bitumen 
    Ranasinghe, HMLU; Madushanka, RD; Liyanage, NMVK [Conference-Abstract]
    Performance of Bitumen modified with thermoplastics based on natural rubber(NR) and Low density polyethylene(LDPE) was investigated. Blending of NR and LDPE in different ratios was done by using a plastic extruder at ...
