Term 2 Week 9

On Thursday last week I was on Solidworks continuing to create my longboard design. On Monday we had double period and spent both periods doing practical on our moulds. I had already finished my mould so helped Anand with his by trimming each piece down. On Monday I also spent some time on the computer to update my calender and start my research on R180 expoxy and also double bias roving fibreglass. On Wednesday I updated my blog and calender and then worked on my solidworks design. On Thursday I may start putting together my board as Terry has bought the needed supplies. Next week I will probably have a mixture of practical and computer work. On the computer I need to finish my solidworks design and also my research on materials. For practical I need to put my board together clamped to my mould.

Fibreglass Research Chop Strand Double Bias Roving

Chop Strand Mat is a general purpose reinforcement material. It is composed of chopped fiberglass of various lengths randomly dispersed to provide equal distribution in all directions, held together with a chemical binder. The end result is a material that creates good stiffness in products when used alone or in conjuction with other fiberglass fabrics. Chop Strand Mat is commonly used because of its low cost and the good bond provided between layers of Woven Roving or fiberglass cloth. It is also commonly used by itself for a wide variety of glassing applications where a thick, heavy, durable, coarse finish is required. Chop Strand Mat is usually categorized by weight per square foot.In most cases the materials are usually a Woven Material or Cloth for high tensile strength along with Chop Strand Mat to reduce labor cost.

The resulting DOUBLE BIAS product is extremely conformable with high strength offering fast wet out. Ideal for hand lay up molding, resin infusion, SRIM, RRIM, and SCRIMP processes. Compatible with polyester, Vinyl Ester, Epoxy, and Polyurethane resin systems. Great for fiberglassing stringers and bulk heads because it will lay down nicely. Heavy duty fiberglass reinforcement common in marine construction. Used where high strength and fast build-up are necessary.

Research Epoxy R180/K180

Nuplex R180 is a modified, low viscosity epoxy resin and is used in conjunction with Nuplex H180 hardener for the construction of reinforced laminates in the Marine environment.

This epoxy system was especially developed for the production of articles where thin film cure is of particular importance. Particular emphasis has been placed on deferral toughness and strength of the cure system. As well as offering high mechanical properties, its low viscosity facilitates wet out of difficult fabrics.

Term 2 Week 8

On Monday I was doing practical work in the workshop. I managed to complete my mould for my longboard with the help from Anand and Sam. Anand and Sam helped by holding my mould together while I screwed the pieces together using a drill. It was quite challenge to align and hold the pieces but the mould looked good at the end. On Wednesday I updated my blog by posting reflections and pictures of my mould. I also continued to work on my final design on solidworks. On Thursday I will probably help Sam out along with Anand to finish his mould as three people are needed to assemble each mould. Next week I may start building up my board on my mould. I will also spend time on the computer to update my blog and work on my solidworks design.

Term 2 Week 7

On Monday I continued to work on my longboard mould. I had to sand down each piece to be ready to put together to make the full mould. On Wednesday I updated my blog my typing up another reflection post and also updated my calender. On Wednesday I also worked on solidworks. On Thursday I started my final longboard design on solidworks. My board is curved two ways so is quite hard for me to create it on the solidworks program. I am gaining experience on solidworks and am now able to create a simple board shape by myself but will need some assistance for making my final design. Next week I will finish my mould by assembling the separate pieces. I will also update my blog by posting reflections, posting pictures and updating my calender.

Term 2 Week 6

This week we had a public holiday so I didn't have DTM on Monday. On Wednesday I updated my blog by posted reflections. I also worked on my longboard design on the solidworks program. On Thursday I was planning to do practical work on my mould but instead we were in the Com labs working on solidworks. On solidworks I started to create my own longboard design which is quite hard as I am not experienced with the program. Next week I will probably work on solidworks and may also work on finishing my mould.

Term 2 Week 5

On Monday P3 I worked on the computer to update my blog, I posted another reflection and also posted a few pictures. P4 I worked on my mould, I continued cutting and sanding out the curveture on each mould piece. Wednesday we had a home learning day so didn't have DTM. On Thursday we had a solidworks tutorial and created a simple skateboard shape. I found it easy to follow along with the tutorial but found it hard to remember the diffferent techniques for the solidworks program. I also posted the end result of the skateboard. Next week I will work on creating my own longboard design on solidworks and may also do practical work on my mould.
